Re: The City of Bozeman Unified Development Code Update - Agricultural Water User Facilities
Dear Commissioners,
Thank you for your continued work updating the Unified Development Code, as this is one of the
most consequential opportunities to protect the irrigation ditch infrastructure that passes through
Bozeman.
The Open Channels Working Group is a collaboration of people with technical expertise and
hands-on experience at the intersection of water and agriculture in the Gallatin Valley.
Throughout the UDC revision process, our group has provided recommendations to strengthen
the City’s regulatory framework so that it supports water users and aligns with state law.
Unfortunately, most of these recommendations are not reflected in the latest draft. The rights of
irrigators are simple, though our code is nuanced.
We are resubmitting our previous recommendations (with one additional recommendation for
managing stormwater discharge) to make the development review process more consistent,
clear, and enforceable when it comes to protecting irrigation facilities (Appendix A).
Additionally, we’ve provided examples of strong subdivision language from other municipalities
or counties in Montana (Appendix B).
We appreciate the recent meeting we had with City staff and Commissioners so we could
understand how our comments were viewed. We understand the need to consider potential
overreach, project timelines, case law, property rights, and growth in the development code.
But the reality on the ground is clear: the current code is not working the way it’s intended.
Applicants don’t always obtain written consent to discharge stormwater or dewatering water into
a ditch. Partial abandonments decided through ditch agreements are routinely misinterpreted as
abandonment system-wide. Ditch companies and water right holders are absorbing the
consequences of development, including water quality impacts, ditch interference and increased
maintenance, and blame for downstream flooding.
At a time of rapid growth and limited capacity in the agricultural community, weakening and
obscuring these protections is a disservice to our neighbors, putting water conveyance, flood
control, infrastructure, aquifer recharge, instream flows, and local trust at risk.
Thank you for your attention to this, and we urge you to amend the code before adoption to
address these discrepancies.
Sincerely,
The Open Channels Working Group

APPENDIX A. Recommendations
Agricultural water user facilities (Sec. 38.310.010.)
RECOMMENDATION 1: Clearly state that Montana State Law prohibits interference with
canal or ditch easements without written consent.
HOW: Explicitly state that consent from the easement holder is required for any proposed
activity, such as realignment, relocation, crossing, diversion, discharge, or other impacts.
Relocate A. Purpose. 2. to B. Notice requirements concerning agricultural water user facilities.
WHY: Our biggest concern stems from on-the-ground experiences: developers are failing to
obtain the proper written consent before moving, abandoning, or discharging water—such as
stormwater or dewatering water—into a ditch.
City staff note their hesitancy to mandate written consent in the code because state law is
constantly evolving, and that making reference to MCA, § 70-17-112 is sufficient. However, our
code, both the existing version and present draft, includes written consent requirements for
certain impacts in Sec. 38.410.060 - Easements. For applicants, city staff, and irrigators alike,
this inconsistency makes the code unclear and confusing to follow.
State law makes protection clear: A person may not encroach upon or otherwise impair any
easement for a canal or ditch unless the holder of the canal or ditch easement consents in
writing. Written consent should be stated clearly in each section of the code that regulates
agricultural water user facilities, particularly Sec. 38.310.010 - Agricultural water user facilities,
to reduce conflicts and ensure compliance with state law. Many municipalities and counties
across Montana explicitly require written consent to interfere with a ditch. Examples have been
compiled in Appendix B.
Most of the language in A. Purpose. 2. was originally located under Sec. 38.410.060 -
Easements. While a purpose statement provides important clarity about intent, it does not
function as a procedural requirement. The paragraph explicitly includes the statement that,
“Relocation or realignment must be approved by the facility owner.” This language belongs in
the section where it can be implemented.
Easements (Sec. 38.410.060.)
RECOMMENDATION 2: Clarify that all agricultural water user facilities are associated with an
existing easement established and maintained by the ditch company or authorized
representative.
HOW: Strengthen the code with clear, directive terms such as “must provide” or “are required to
submit” to further reduce ambiguity and ensure consistent application.
Remove the minimum 10-foot easement width and any language implying that developers are
responsible for establishing new easements on agricultural water user facilities.
WHY: Generally, ditch companies and water right owners hold water rights, a prescriptive
easement to convey water through a ditch itself, and a secondary easement for access and
maintenance under state law. An easement on a ditch is worked out between the ditch’s
authorized representative and the developer based on what is needed and reasonable on-site
due to access points, topography, maintenance, conveyance capability, and more.
Current language around the establishment or existence of easements is ambiguous, using
terms such as “may be required” or “may be subject to,” which imply uncertainty about existing
rights. It also suggests that developers are responsible for establishing the ditch easement
themself, which is inaccurate and inconsistent with state law. Removing the minimum easement
and clarifying ditch users’ rights underscores the importance of coordination with ditch
companies and sets expectations for both parties from the get-go.
RECOMMENDATION 3: Clearly state that written consent is required from a ditch company if
the applicant is proposing to discharge stormwater or dewatering water into a ditch.
HOW: In the November 18th City Commission meeting, City staff recommended reverting back
to the original language in Sec. 38.410.060 - Easements where written consent is required for a
developer to discharge stormwater into a ditch.
Extend the same requirement for construction dewatering water. For example, the paragraph
could be edited to read, “Stormwater and construction dewatering water must not be discharged
to an agricultural water user facility without written approval from the owner of the facility and
corresponding stormwater conveyance easements.”
WHY: We appreciate the City’s willingness to address concerns about replacing the written
consent requirement with a standard that discharge must not “unreasonably impair” a ditch
easement. Applying the same written consent requirement to construction dewatering would
clearly establish that any discharge must occur in coordination with, and with approval from,
authorized ditch users.
Irrigators report that developers are increasingly obtaining DEQ permits for stormwater or
construction dewatering discharges, but are not obtaining permission from authorized users to
discharge into the ditch. Stormwater or groundwater dewatering discharge, especially when not
planned for in coordination with a ditch’s authorized user, is an inherent impairment under MCA
70-17-112. The quality of water entering a ditch directly affects downstream users, and added
volume can exceed the ditch’s capacity, leading to flooding, erosion, and infrastructure damage.
Municipalities and counties across Montana explicitly include written consent requirements for
discharging stormwater (Appendix B), and Gallatin County’s language includes stormwater,
snowmelt runoff, and water from dewatering activities.
Submittal Materials and Requirements. (Division 38.710.)
RECOMMENDATION 4: Require written consent from the ditch company or authorized
representative when a developer proposes to encroach or impact it in any way. (See #1)
RECOMMENDATION 5: Require the submission of written consent to discharge stormwater
or dewatering water into a ditch. Include a dewatering permit in Sec. 38.710.020. (See #3)
APPENDIX B. Written Consent Requirements: Relocation, alteration, and
stormwater discharge in Subdivision Regulations.
