1 Introduction
1.1 Project Overview
River Design Group, Inc. (RDG) was retained by The Trust for Public Land (TPL) to perform a
wetland delineation encompassing approximately 75 acres in Bozeman, MT, at the Story Mill
project site (Figure 1). The purpose for the delineation of wetlands at the site is to provide
baseline information to support future potential restorative measures, designed to increase
wetland functions and values as well as stream channel and aquatic habitat functions. Wetland
delineation fieldwork was performed July 9-13, 2012 by RDG, in accordance with the Army
Corps of Engineers Wetland Delineation Manual (1987) and the appropriate Regional
Supplement (2010). Wetland delineation results will be utilized in appropriate permit
applications In compliance with Section 404 of the federal Clean Water Act (CWA).

1.2 Geographic Jurisdiction
Discharge of dredged or fill material into Waters of the U.S. is regulated by Section 404 of the
CWA. The U.S. Army Corps of Engineers (USACE) retains jurisdiction over Waters of the U.S.
which include traditional navigable waters, their tributaries, and all other waters including
wetlands that are adjacent to Waters of the U.S. Following various court decisions, the term
‘adjacent’ refers to wetlands that are bordering, contiguous, or neighboring a Traditional
Navigable Water of the U.S., or a tributary to one. Wetlands, as ‘Special Aquatic Sites’, receive
special treatment under CWA Section 404, and are defined as the following:
Those areas that are inundated or saturated by surface or ground water at a frequency
and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands
generally include swamps, marshes, bogs, and similar areas. (USACE 1987).
In 2001 in the case of Solid Waste Agency of Northern Cook County (SWANCC) v. United States
Army Corps of Engineers, the Supreme Court ruled the USACE does not have the authority to
regulate isolated, intrastate waters based solely on the Migratory Bird Rule. This rule previously
granted jurisdiction as migratory bird species traveled between isolated wetlands and
Traditional Navigable Waters. Current regulatory standing, which includes the Rapanos Case
Decision (case decision in 2006, and EPA/Army Corps memorandum in 2008), states the USACE
will assert jurisdiction in areas of Traditional Navigable Waters (TNW), wetlands adjacent to
TNW, non-navigable tributaries of TNW (relatively permanent and those that are not relatively
permanent), and wetlands adjacent to any TNW or tributary even if they do not directly abut a
relatively permanent water, granted they have a ‘significant nexus’ to a TNW or interstate
water (547 U.S. 715).
Both streams on the Story Mill project site (Bozeman Creek and East Gallatin River) are
perennial and fall under USACE jurisdiction. Wetland types found on the project site by RDG
include wetlands directly abutting the streams (Freshwater Emergent Wetlands - Streambank),
wetlands neighboring but not directly adjacent to the streams (Freshwater Emergent Wetlands
– Depressional), an open water wetland, and a small ditch (Story Mill Ditch) that empties into
East Gallatin River when flowing. All three wetland types and the ditch will likely be subject to
USACE regulation under the Clean Water Act and recent court rulings; however the USACE
maintains full authority for jurisdictional determinations.
2 Methods
Wetland delineation methods employed by RDG comply with the Corps of Engineers Wetlands
Delineation Manual (1987) and the Regional Supplement to the Corps of Engineers Wetland
Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (2010), for
onsite routine determinations for areas greater than five acres in size. As outlined in the 1987
manual and 2010 regional supplement, an area is determined a wetland only if it meets all
three wetland criteria with at least one primary indicator in each (USACE 1987):
Story Mill Wetland Delineation
-3- July 2012
1. Wetland Hydrology: “All hydrologic characteristics of areas that are periodically
inundated or have soils saturated to or near the surface during a portion of the growing
season.”
2. Hydric Soil: “A soil that formed under conditions of saturation, flooding, or ponding long
enough during the growing season to develop anaerobic conditions in the upper part.”
3. Hydrophytic Vegetation: “The sum total of macrophytic plant life that occurs in areas
where the frequency and duration of inundation or soil saturation produce permanently
or periodically saturated soils of sufficient duration to exert a controlling influence on
the plant species present.”
Four transects were located on the project site, approximately 400-feet to 700-feet apart
depending on the location. In general, sampling plots were established along transects where a
distinct break in vegetation and/or hydrology was observed. A USACE Wetland Determination
Data Form was filled out for each plot (Appendix B), and a determination of wetland status was
made based on the presence or absence of the three wetland criteria (hydrology, soil,
vegetation). Soil pits were excavated to at least 16-inches below the surface where not
restricted by an impermeable layer. Soil color in each soil horizon was characterized with the
use of a Munsell soil-color chart, and texture was determined by hand. Presence of redox
features was observed, and their color, percent, type, and location was recorded on data forms.
Vegetation was sampled by stratum, with a 30-foot radius circular plot used for a tree stratum,
a 15-foot radius circular plot used for a sapling/herb stratum, and a 5-foot radius circular plot
utilized for an herb stratum. Photos of the soil and vegetation were obtained for each plot
(Appendix A), and a GPS point was collected using a Trimble GeoXT mapping-grade GPS
receiver. All GPS data is characterized by sub-meter accuracy after differential correction.
Following the plot-scale wetland/upland classification along transects, wetland boundaries
were determined by walking the area between transects and making adjustments based on
observed vegetation and soil. Wetlands were mapped with GPS as complete polygons or lines
demarking the wetland/upland boundary. Points along wetland boundaries in the Freshwater
Emergent Wetland – Depressional type were staked with survey lathe, marked with orange
flagging, and numbered sequentially starting from the southwest corner of the wetland area
and proceeding in a clockwise direction. Survey lathe was also installed on the boundary of the
Freshwater Emergent Wetland - Streambank type along East Gallatin River, numbered
sequentially going downstream on river left, and upstream on river right. Wetland area on
Bozeman Creek was limited to three small streambank sites and is not lathed. Land adjacent to
Story Mill Ditch was determined not to exhibit all three USACE wetland criteria, thus only the
immediate ditch is mapped as a Water of the U.S.
Existing data and information used to complement field data collection efforts include the
following sources: Gallatin County Soil Survey (Soil Survey Staff 2012), National Wetlands
Inventory (USFWS 2012), and National Agricultural Imagery Program 2009 aerial imagery (US
Farm Service 2009).

3 Site Description
3.1 Project Site Overview The Story Mill project site is located in Bozeman, MT, at approximately 45°41ꞌ55ꞌꞌ N, 111°1ꞌ21ꞌꞌW in Gallatin County (Figure 1). It encompasses portions of SE ¼ of Section 31 and SW ¼ of Section 32 in Township 1S, Range 6E, as well as portions of NE ¼ of Section 6 and NW ¼ of Section 5 in Township 2S, Range 6E, P.M.,M. Six parcels of interest are located within the wetland assessment area (Figure 2), and wetland findings are presented both cumulatively for the entire area, as well as by parcel. For the period of record of 1981 to 2010, average temperature ranged between 14°F (January) to 83°F (July), with average annual total precipitation of 19.7 inches (WRCC 2012). For the month of June (1981-2010), mean precipitation was 3.1 inches, while temperature ranged between 41 and 74°F. In June 2012 (month prior to the wetland delineation field effort), precipitation totaled 1.5-inches while temperature fluctuated between 33 and 92°F.
3.2 Hydrology Two perennial streams flow through the project area, the East Gallatin River and Bozeman Creek (Figure 2). Bozeman Creek, with headwaters approximately 15 miles southeast of the project site in the Gallatin Range, flows south to north and into the East Gallatin River on the northwest border of the project site. East Gallatin River originates at the confluence of Rocky Creek and Bear Creek roughly 5 miles southeast of the project site. It flows to the northwest for 42 miles before its confluence with the Gallatin River. Annual discharge in the East Gallatin River ranged between 67 and 212 cfs (USGS gage site 06048700, below Bridger Creek), for water years 2002 - 2011 (USGS NWIS 2012). Common primary indicators of wetland hydrology documented by RDG at wetland sites include soil saturation within 12-inches of the surface and a hydrogen sulfide odor. Some wetland plots exhibited high water tables and oxidized rhizospheres along living roots. A common secondary wetland hydrology indicator was Geomorphic Position in the landscape.
3.3 Soils The NRCS Soils database lists five major soil units in the Story Mill project area (Figure 3, and Appendix C). The major units within the study site (407A, 512B, 606A, 523A, and 542A) are classified as loams occurring on floodplains and stream terraces. Parent material is alluvium, loamy alluvium, or sandy alluvium, with slope gradients of 0 to 4 percent. Of the major soil units in the project area, only 407A, Sudworth-Nesda loams, does not exhibit hydric soil characteristics. In units 512B and 523A, the Nythar and similar soils are hydric, 542A Blossberg loam is hydric, and in soil unit 606A, Bandy and similar soils as well as Bonebasin and similar soils are listed as hydric. The Riverwash portion of soil unit 606A is unranked. Appendix C includes a characterization of all NRCS-defined soils at the site.
Story Mill Wetland Delineation
-5- July 2012
Wetland soils documented by RDG during the routine wetland delineation include soils with textures of loam, sandy loam, sandy clay loam, silt loam and silty clay loam. Matrix colors of very dark gray, black, and very dark brown occurred frequently, and dark gray depleted matrices and gleyed matrices were less common. Redoximorphic features within profiles commonly consisted of concentrations of dark yellowish-brown, strong brown and gleyed colors, mostly located within the soil matrix but sometimes occurring along pore linings. All redox features used in hydric soil determinations were distinct or prominent.
3.4 Vegetation
The Montana Land Cover Atlas, a product of the Montana Gap Analysis project (Fisher et al.
1998), is a broad-scale (90x90m pixel resolution) vegetation classification system developed at
the Wildlife Spatial Analysis Lab at the University of Montana. Five GAP-Analysis cover types
occur within the Story Mill project site. The majority (74%) is classified as Urban or Developed
lands (Table 3-1).
Table 3-1. GAP Analysis Land Cover Classification, Story Mill project site
Classification Acres Percent of Total
Urban or Developed Lands 55.3 74%
Low/Moderate Cover Grasslands
6.6 9%
Agricultural Lands - Irrigated 6.3 8%
Agricultural Lands - Dry 3.2 4%
Douglas-Fir Forest Lands 2.5 3%
Graminoid & Forb Riparian 0.8 1%
TOTAL 74.7 Hydrophytic vegetation determinations were made using the 2012 Wetland Plant List, effective June 21, 2012 (Lichvar and Kartesz 2012). Vegetation classes characterized by RDG included wetland and upland grasslands, wetland sedge/rush/cattail communities, riparian shrub and riparian forested communities. Common grassland species include
Bromus inermis (smooth brome), Phalaris arundinacea (reed canary grass), Elymus repens (quackgrass/creeping wild rye), Poa spp., and Agrostis stolonifera (spreading bent/redtop). Riparian shrub and forested communities were commonly characterized by species such as Salix exigua (sandbar willow), Salix fragilis (crack willow), Populus tremuloides (quaking aspen), Populus balsamifera ssp. trichocarpa (black cottomowood), and Symphoricarpos albus (common snowberry). Carex utriculata and juncus articus often occurred alongside Equisetum spp. (horsetail) and Typha latifolia (cattail) plants in some depressional wetlands.

3.5 National Wetlands Inventory
The U.S. Fish and Wildlife Service published National Wetlands Inventory is designed to provide
coarse-resolution baseline data for wetland types across the United States. Two major types of
Freshwater Emergent Wetlands occur on the project site, code PEMA and PEMC, and Riverine
and Freshwater Ponds are present in smaller proportions (Figure 4). The list below is adapted
from USFWS 2012, Branch of Resource and Mapping Support:
1. Code PEMA: Palustrine System, Emergent Class, with a Temporary Flooded Water
Regime. Surface water in this water regime is present for brief periods during growing
season, but the water table usually lies well below the soil surface for most of the
growing season.
2. Code PEMC: Palustrine System, Emergent Class, with a Seasonally Flooded Water
Regime. Surface water here is present for extended periods especially early in the
growing season, but is absent by the end of the growing season in most years. The
water table after flooding ceases is variable, extending from saturated to the surface to
a water table well below the ground surface.
3. Code R3UBH: Riverine System, Upper Perennial Subsystem, Unconsolidated Bottom
Class, Permanently Flooded Water Regime (water covers the land surface throughout
the year in all years).
4. Code PABFx/h: Palustrine System, Aquatic Bed Class, Semipermanently Flooded Water
Regime, x: Excavated (artificially created by man), h: Diked/impounded (created by a
man-made barrier). Surface water persists throughout the growing season in most
years, and when absent, the water table is usually at or very near the land’s surface.
National Wetlands Inventory data is based primarily on aerial photo interpretation, 1:24,000
topographic maps and county soil surveys, with field reconnaissance on representative wetland
types (USFWS 2012). It therefore serves as good baseline data, but does not preclude
performing a wetland delineation. Wetlands documented by RDG include Depressional
Freshwater Emergent Wetlands in and around the vicinity of the NWI PEMA and PEMC types, as
well as Streambank Freshwater Emergent Wetlands (not documented in NWI) along riverine
corridors, one open water wetland (a man-made pond), as well as two perennial streams
(Bozeman Creek and East Gallatin River) and the Story Mill Ditch, all described in detail in the
following section.

Of the total 74.7 acres in the wetland assessment area, 10 acres (13%) were determined to be
wetland or a Water of the U.S. Depressional Freshwater Emergent Wetland comprised the
majority (60%) of the wetlands found at the project site, with Streambank Freshwater
Emergent Wetlands at 16% of the total wetland area. The one man-made pond on the
Turner/Griffen property is 0.51 acres (5%), and other Waters of the U.S., including East Gallatin
River, Bozeman Creek, and Story Mill Ditch comprise 19% of the total wetland area on the Story
Mill project site.
Wetland distribution has been impacted by recent human activity. The pond at the
Turner/Griffen property is man-made, and excavated material was placed around the pond
creating bermed upland conditions. A narrow wetland fringe currently defines the pond
perimeter. The pond outlet and large ditch to the north which drains the pond contributes to
the wetland conditions found around the ditch, which include a wide swath of wetland
dominated by cattail (See Plot 19 photo). This ditch extends all the way down to East Gallatin
River; however a beaver dam restricts flow close to the outlet and has created backwater
conditions conducive of wetland development to the south and east of the dam (Figure 5). Two
other major drain ditches exist within the project area, one to the west of the man-made pond
which drains wetland area into the pond outlet ditch, and one toward the middle of the area
around Plot 18.
A distinct break in riparian forest and wetland exists on the Turner/Griffen parcel, as shown on
the aerial photograph of the parcel in Figure 2. This line break is indicative of land conversion
for agriculture or livestock operations. Other major anthropogenic disturbances include berms
created on the East Gallatin River river right floodplain area, and placement of concrete riprap
on banks, most of which are currently slumping into the river.

-8- July 2012
4.1 Freshwater Emergent Wetland, Depressional
A total of 5.95 acres of Depressional Freshwater Emergent Wetlands were found in the Story
Mill wetland assessment area, with 81% of this wetland type occurring on the Turner/Griffen
parcel. Some of this area had standing surface water during wetland delineation field work,
mainly in the center of the wetland areas (northeast of Plot 11, southwest of Plot 8, and
throughout the ditch south of the beaver dam). Nine sampling plots were located throughout
this wetland type (Figure 5).
The most common primary indicator of wetland hydrology at the sampling plots within the
Depressional Freshwater Emergent Wetlands was soil saturation within 12-inches of the soil
surface. Most plots exhibited saturation between 9 and 11-inches, the relatively deep
saturation is likely due to the unseasonably hot and dry June and early July prior to field work.
The wetland pond fringe soil distinctly smelled of hydrogen sulfide and saturation was present
at the soil surface. The water table was present at 9-inches, and soil saturation was at the
surface at the large L Street parcel wetland site (Plot 3A). Plot 3, a depressional anomaly at L
Street parcel, exhibited saturation at 2-inches as well as a hydrogen sulfide odor.
Hydric soil indicators at this wetland type consisted of indicators A11 (Depleted Below Dark
Surface), F6 (Redox Dark Surface), F3 (Depleted Matrix), and A4 (Hydrogen Sulfide). Common
soil matrix colors were black (7.5YR 2.5/1), very dark gray (7.5YR 3/1), dark gray (10YR 4/1),
very dark grayish brown (10YR 3/2), and very dark brown (10YR 2/2). Redox features ranged in
color from pink (7.5YR 7/3) depletions to black (10 YR 2/1), gleyed (GLEY1 2.5/N), and strong
brown (7.5YR 4/6) concentrations, and mostly occurred in the matrix. Textures consisted of
sandy clay loam, loam, and silt loam, and Plot 3A had peaty muck throughout the excavated
profile.
All wetland plots passed the Dominance Test for hydrophytic vegetation (>50% of dominant
species across all strata are OBL, FACW, or FAC). Tree species were not observed in this wetland
type. Vegetation in the sampling/shrub stratum included only one species, Salix exigua
(sandbar willow). Dominant vegetation in the herb stratum consisted of Phalaris arundinacea
(reed canary grass), Typha latifolia (broad leaf cattail), Phleum pratense (common timothy
grass), Deschampsia caespitosa (tufted hairgrass), Bromus inermis (smooth brome), Carex
utriculata (Northwest Territory/beaked sedge), Juncus articus (arctic/baltic rush), and
Alopecurus pratensis (field meadow-foxtail).
Other non-dominant vegetation observed in the herb stratum at Depressional Freshwater
Emergent Wetland sites include Cirsium arvense (Canadian thistle), Hordeum jubatum (fox-tail
barley), Elymus trachycaulus (slender wild rye), Agrostis stolonifera (spreading bent/redtop),
Equisetum laevigatum (smooth scouring-rush), Taraxacum officinale (common dandelion),
Elymus repens (quackgrass/creeping wild rye), Rumex occidentalis (Western dock), and Mentha
arvensis (American wild mint).

-9- July 2012
4.2 Freshwater Emergent Wetland, Streambank
Large floodplain areas on both banks of East Gallatin River, as well as three small areas adjacent
to Bozeman Creek were characterized as Streambank Freshwater Emergent Wetland (1.59
acres total). All three parcels with East Gallatin River flow exhibited this wetland type, with the
Henderson parcel having the most (0.74 acres, 47%), followed by the Wake Up, Inc. parcel (0.67
acres, 42%), and L Street parcel (0.16, 10%). The Turner parcel with Bozeman Creek flow had a
minimal 0.02 acres (1%) of this wetland type. Six sampling plots were located throughout
Streambank Freshwater Emergent Wetland areas (Figure 5).
Soil saturation (indicator A3) was the most common primary indicator of wetland hydrology in
this wetland type, and was found between 3 and 8 inches from soil surface. A hydrogen sulfide
odor was detected at Plot 21B. Plot 23 on the Henderson parcel exhibited sediment and drift
deposits, as well as the secondary indicators of drainage patters and geomorphic position in the
landscape.
Hydric soil indicators at streambank wetland sampling plots included Sandy Redox (indicator S5)
and Hydrogen Sulfide (indicator A4). Plots 2, 14, and 23 exhibited problematic hydric soils. Soil
profiles in the three plots displayed dark surfaces and redox features, but did not qualify for
indicator F6 (redox dark surface) as the concentrations were not entirely contained within the
upper 12-inches of the profiles. These plots were, however located on active floodplain surfaces
and fall into the ‘recently developed wetland’ category. The floodplain location of these plots is
indicative of periodic flooding events during high river stage, as well as fluctuating groundwater
levels. The definition of hydric soils, “a soil that formed under conditions of saturation, flooding,
or ponding long enough during the growing season to develop anaerobic conditions in the
upper part" (USACE 1987), therefore should be met at these sites. Moreover, Plot 14 had large
woody roots in the lower horizon between 7-16 inches, which exhibited a strong hydrogen
sulfide odor.
Common soil matrix colors included very dark gray, dark brown (7.5YR 3/1 and 3/2), very dark
grayish brown and dark gray (10YR 3/2 and 4/1). Redoximorphic features consisted of
concentrations located mostly in the soil matrix, commonly exhibiting colors of strong brown
(7.5YR 4/6), yellowish red (5YR 4/6), or gley (GLEY 1 3/N). Observed soil textures in the
Streambank Wetlands included sand, loamy sand, sandy loam and loam.
All plots in this wetland type passed the Dominance Test for hydrophytic vegetation. Dominant
species observed in the tree stratum at these sites included Populus balsamifera ssp.
trichocarpa (black cottonwood), Alnus incana (speckled alder), Salix bebbiana (grey willow), and
Salix boothii (Booth’s willow). Prunus virginiana (choke cherry) was present in Plot 15 with non-
dominant cover. In the sapling/shrub stratum, dominant species encountered included Salix
fragilis (crack willow), Salix exigua (sandbar willow), A. incana, S. bebbiana, Rosa woodsii
(Woods’ rose), and Cornus alba (Red-osier dogwood). Non-dominant species documented in
Story Mill Wetland Delineation
-10- July 2012
the sapling/shrub stratum were Ribes triste (swamp red currant), Ribes hudsonianum (Northern
black currant), and C. alba.
In the herb stratum, dominant species included P. arundinacea (reed canary grass), B.inermis
(smooth brome), Tanacetum vulgare (common tansy), M. arvensis (American wild mint), D.
caespitosa (tufted hairgrass), E. repens (quack grass), and C. arvense (Canadian thistle). Species
present in non-dominant cover in the herb stratum are C. arvense, P. pratense (common
timothy grass), Dactylis glomerata (orchard grass), T. officinale (common dandelion), P.
arundinacea, E. repens, Conium maculatum (poison hemlock), Urtica dioica (stinging nettle),
Equisetum pratense (meadow horsetail), T. vulgare, B. inermis, and Poa pratensis (Kentucky
blue grass).
4.3 Other Wetland Sites and Waters of the U.S.
4.3.1 Open Water Wetland
One open water wetland was found on the Story Mill project site, the 0.51-acre man-made
pond on the Turner/Griffen parcel. A very narrow wetland fringe (classified as Depressional
Freshwater Emergent Wetland) is present around the pond. Boundaries between open water
wetland and the wetland pond fringe are demarcated by the water’s edge and a shift from
either no vegetation or an aquatic bed, to rooted hydrophytic vegetation.
4.3.2 Perennial Rivers and Streams, and Story Mill Ditch
Both East Gallatin River and Bozeman Creek are classified as Waters of the U.S., as they both
are perennially flowing streams. East Gallatin River bankfull width averages around 30 feet with
a total area of 1.6 acres throughout the Story Mill project area, while the smaller Bozeman
Creek averages roughly 20-feet in bankfull width (0.2 acres total) through the project site. Story
Mill Ditch empties into East Gallatin River when flowing; however at the time of wetland
delineation field work the entire ditch was very dry. Emergent wetland was not found on the
banks of the ditch (see Plot B data form and pictures). The total area of Story Mill Ditch on the
project site is estimated at 0.2 acres.
4.4 Upland
Most of the Story Mill wetland assessment area was found to be upland, with a total of 64.7
acres or 87% of the total land area. Much of this upland area is concentrated in the Mill and
Wake Up, Inc. parcels, with significant development on these lands (the old Story Mill and
associated buildings). The northern portion of the Henderson parcel is also all upland, as is the
eastern half of the L Street parcel. Seventeen sampling plots were located on upland areas
throughout the project area (Figure 5).
No indicators of wetland hydrology were found on upland sampling plots, other than a
secondary indicator of Geomorphic Position at Plots B (adjacent to Story Mill Ditch) and 21A
Story Mill Wetland Delineation
-11- July 2012
(high floodplain terrace on Bozeman Creek). No surface water, high water tables, or saturation
were present in upland plots.
Upland soils exhibited dark colors, e.g. black (10YR 2/1), very dark brown (10 YR 2/2), and very
dark grayish brown (10YR 3/2). Some redox concentrations were present, e.g. Plot 20 exhibited
2% dark yellowish brown (10YR 4/4) concentrations in the matrix. One plot (Plot 22 on the
Henderson parcel) exhibited hydric soil, with indicator A11 (Depleted below Dark Surface) and
5% distinct redox concentrations and depletions, which is indicative of historically wetter
conditions at that upland site. Soil textures were comprised of loam, sandy loam, clay loam,
silty clay loam, and silt loam.
Most upland sites (71%) passed the Dominance Test and exhibited hydrophytic vegetation.
However many of these sites were dominated by B.inermis (smooth brome), with a new 2012
wetland indicator status of FAC, and therefore lumped with hydrophytic vegetation when it
often occurs in very dry upland sites (e.g. Plot A). Other dominant vegetation in upland plots in
the herb stratum included P. arundinacea (reed canary grass) E. repens (quackgrass), C. arvense
(Canadian thistle), P. pratense (common timothy grass), H. jubatum (foxtail barley), A.
stolonifera (redtop), and T. vulgare (common tansy). All aforementioned species besides P.
arundinacea (FACW), and T. vulgare (FACU) have a 2012 wetland indicator status of FAC. The
tree stratum in upland plots was dominated by species such as P. virginiana (choke cherry),
Lonicera utahensis (rocky Mountain honeysuckle), Populus tremuloides (quaking aspen), P.
balsamifera (black cottonwood), and Salix fragilis (crack willow). The sapling/shrub stratum was
often dominated by R. woodsii (woods’ rose), S. exigua (sandbar willow), Symphoricarpos albus
(common snowberry), and P. tremuloides.
5 Conclusion
Ten acres of wetlands and perennial streams were found at the Story Mill project site by RDG.
These include both Depressional and Streambank Freshwater Emergent Wetlands, one Open
Water Wetland, two perennially flowing streams (Bozeman Creek and East Gallatin River), and
Story Mill Ditch. All wetland and stream areas should fall within USACE regulation, however the
USACE will make the final jurisdictional determination, especially with regard to Story Mill
Ditch.
