Lakes, Streams & Wetlands

Program Overview

The Water Quality Planning Bureau is responsible for administering four vital functions related to the Clean Water Act. 

Visit the Clean Water Act Information Center on the Resources page to find information about the quality of Montana's rivers, streams, and lakes in relation to Montana's water quality assessments. These assessments are based on available statewide water monitoring data and information. The Clean Water Act Information Center also provides access to Montana's Water Quality Reports and List of Impaired Surface Waters, as well as online search and mapping tools.

Clean Water Act Information Center


Water quality standards consist of several parts:

  • Beneficial uses — Identify how people, aquatic communities, and wildlife use our waters
  • Numeric standards — Amounts of specific pollutants allowed in a body of water and still protects it for the beneficial uses
  • Narrative standards — Statements of unacceptable conditions in and on the water
  • Nondegradation protections — Extra protection for high-quality or unique waters and existing uses

Together, the beneficial uses, numeric and narrative standards, and nondegration protections provide the framework for achieving Federal Clean Water Act and Montana Water Quality Act goals and protecting Montana water resources.

Monitoring & Assessment

DEQ’s Water Quality Monitoring and Assessment Section assesses whether state waters meet water quality standards and support beneficial uses. Beneficial use assessment is one step in the water quality planning process; it requires monitoring and informs Total Maximum Daily Loads (TMDLs) and water quality protection and restoration. Tracking changes in water quality may also be important to determine if conditions are improving or deteriorating over time. DEQ supports numerous professional and volunteer monitoring partnerships across Montana that align with our vision.

Watershed Protection

Watershed Protection section is responsible for administering the Nonpoint Source Program and TMDL program

Total Maximum Daily Load (TMDL) Program

The Total Maximum Daily Load (TMDL) Program identifies sources of pollution to streams, rivers, and lakes within Montana and determines how much pollution those waters can sustain and still fully support beneficial uses. Plans are then written that outline how to reduce pollution to those waters while offering ways to assist local communities with finding solutions to restore and maintain clean water.

Nonpoint Source Program

Nonpoint source pollution typically comes from diffuse sources, such as grazing, timber harvest, abandoned mine lands, irrigation, recreation, and septic systems. It includes a wide range of pollutants and conditions, including nutrients (nitrogen and phosphorus), heavy metals, sediment, loss of riparian habitat, streamflow alteration, and temperature changes. Montana’s goal is to provide a clean and healthy environment by protecting and restoring water quality from the harmful effects of nonpoint source pollution. We believe this can best be achieved through voluntary implementation of land, soil, and water conservation practices.

Harmful Algal Blooms

Nonpoint source pollution can cause harmful effects such as harmful algal blooms (HABs), which are an overgrowth of cyanobacteria. Some types of cyanobacteria can produce toxins that can pose serious health risks to humans and animals if toxins are contacted or ingested. HABs typically occur on lakes and reservoirs when water conditions (e.g., light, temperature, and nutrient levels) promote growth; typically, in summer and fall in Montana. If in doubt, stay out.

Wetlands are valuable for providing flood and erosion control, enhancing water quality, and providing wildlife and fish habitat. Wetlands continue to be impacted and lost as roads are expanded, land is developed, and due to cumulative impacts from numerous activities such as draining, changes in land management, and landowner preference for open water ponds. DEQ's Water Quality Planning Bureau is responsible for coordinating and providing leadership to wetland conservation activities statewide. These projects range from an Evaluation of Wetland Impacts in the State of Montana, to Developing Education and Information about Montana Wetlands, to a Local Partnership composed of local government, wetland ecologist, and community volunteers to inventory wetlands for restoration and management needs.

Submit Data

DEQ provides detailed guidance to organizations, individuals, and laboratories on how to submit ambient water quality data to DEQ. Montana uses a system called the Montana EquIS Water Quality Exchange (MT-eWQX) to store water quality monitoring data, including physical, chemical, biological and habitat data, from locations across the state. Once verified, these data are submitted to EPA's Water Quality Portal, where they are publicly available.

The steps below are provided to help organizations and volunteers submit their data through DEQ's data portal.

Step 1: Prepare Your EDD

Data must be submitted to MT-eWQX in a specific electronic format known as an Electronic Data Deliverable (EDD). Data providers are required to download the MT-eWQX EDD and populate it with the project data to be submitted. Detailed guidance for populating the MT-eWQX EDD can be found in the MT-eWQX Guidance Manual.

MT-eWQX EDD MT-eWQX Guidance Manual


Step 2: Validate Your EDD

After the MT-eWQX EDD is populated, all data must be validated using the EQuIS Data Processor (EDP). The EDP is a standalone application that allows data providers to check their EDD files prior to submission to ensure they are formatted correctly. The EDD must have a clean validation from the EDP prior to data submission to DEQ. Refer to the EDP Guidance Manual for detailed instructions.

EDP Guidance Manual Download EDP

Step 3: Submit Your EDD

In order to submit an EDD, the following are required:

  • Completed MT-eWQX Data Submittal Form
  • Final MT-eWQX EDD
  • Associated project QAPP and/or SAPs and any other attached documents referenced in the EDD

Information about all the above requirements can be found within the MT-eWQX Guidance Manual.

Why Water Quality Standards

  • Protect water resources for uses such as fishing, swimming and other recreation, and sustaining fish, bugs, plants, and other aquatic life
  • Are a measure to identify polluted waters or healthy waters in need of protection
  • Guide the limits set on what regulated facilities can discharge to surface water

The federal Clean Water Act requires states to designate beneficial uses for all waters and develop water quality standards to protect each use.

States either develop their own criteria or implement federal criteria for evaluating water quality. These criteria must accurately reflect the latest scientific knowledge. They are based solely on data and scientific judgments about pollutant concentrations and their effects on the environment, aquatic life, and human health. Montana water quality criteria include both numeric and narrative criteria. Water quality criteria for each use class are detailed in the Montana Code Annotated. Additionally, a detailed map of Montana's use classes can be found HERE. (Please note that this map is data intensive, for mobile user or slow internet connections a pdf map is provided HERE) (Note: Montana does not designate use classes for Tribal Nations). Additionally, a map detailing Montana’s Outstanding Resource Waters can be found HERE.

Numeric Criteria

Most of Montana’s water quality criteria are numeric; that is, the criteria define precise, measurable concentrations of pollutants that if exceeded would harm the use. Montana’s numeric water quality criteria are published in Circular DEQ-7 and Circular DEQ-12A.

Montana also has Nutrient Standards Variances which are published in Circular DEQ-12B.

Narrative Criteria

Some pollutants have narrative water quality criteria, which are statements (instead of specific quantities) that describe the desired water quality condition in terms of allowable ranges and maximums (e.g., water pH and temperature) or in terms of specific variation from natural conditions (e.g., water turbidity and color). Each use class defined in the rule has narrative criteria, and some narratives define an allowable change from naturally-occurring conditions. Naturally-occurring conditions are determined by reviewing historical data for a waterbody, if available, or by comparing conditions with a reference waterbody, an unaltered or otherwise in its most natural condition.

Montana’s water quality standards and details of how water quality standards are implemented in point-source discharge permitting are contained in Montana Administrative Rules. All current state water rules and Montana water quality standards are available on the Water Quality Regulations and Forms page.


Nondegradation protections maintain high quality waters from deterioration. Montana’s Nondegradation policy provides three levels of protection for surface waters:

  1. Existing uses of the water body must be maintained and protected.
  2. High water quality (water quality better than the applicable water quality standard) must be maintained unless a lowering of water quality is necessary to accommodate important economic and social development.
  3. Exceptional characteristics of specific waters designated as outstanding, very sensitive, or unique resources -- called outstanding resource value water -- must be maintained and protected.

Monitoring & Assessment

DEQ monitors chemical, physical, and biological properties of our state’s rivers, streams, lakes, and wetlands. High quality data is necessary to support decision-making. DEQ monitors water quality to:

  • Educate people about water quality;
  • Inform watershed restoration and protection plans;
  • Track trends in water quality;
  • Investigate water quality problems, threats, and improvements;
  • Assess whether waters meet water quality standards and support beneficial uses;
  • Evaluate sources of pollution;
  • Support studies that determine total maximum daily load (TMDL) development;
  • Establish baseline conditions;
  • Develop water quality standards.

Across Montana, trained volunteers monitor water quality in our rivers, streams, lakes, and wetlands. Volunteer monitoring is a fun and effective tool to educate people about protecting water quality and to engage communities in pollution prevention and restoration. Volunteer monitoring programs are administered by watershed groups, conservation districts, water quality protection districts, non-profit organizations, schools, and other entities. DEQ also provides volunteer monitoring opportunities.

Each volunteer monitoring program is driven by a unique set of monitoring objectives. Volunteers may collect chemical, physical, or biological parameters to evaluate water quality, aquatic habitat, and streamflow. Whether they collect high-quality data for decision-making, or monitor solely for educational purposes, DEQ values the contribution of volunteer monitoring programs.

DEQ’s Volunteer Monitoring Support Program supports volunteer monitoring in several ways:

  • Financial support, such as our Volunteer Monitoring Lab Analysis Program;
  • Technical support, such as trainings and guidance documents;
  • Administering volunteer monitoring opportunities; and
  • Forming partnerships with other entities in the state that also support volunteer monitoring.


Volunteer Monitoring Lab Analysis Support Program

Each year, DEQ seeks applications for up to $5,000 from volunteer monitoring programs seeking financial assistance with laboratory sample analysis and shipping costs associated with water quality monitoring projects. Applicants are required to submit an application, a Sampling and Analysis Plan (SAP), and an analytical budget which matches their funding request. This program is for laboratory analysis and sample shipping costs only and does not include funding for Sampling and Analysis Plan (SAP) development, travel, monitoring time, purchasing and maintaining field equipment, or other operational costs. All data that is collected using these funds must be uploaded by the awardee to DEQ’s water quality database (MT-eWQX).

Beneficial use assessment of Montana's rivers, streams, and lakes is tied to goals of the federal Clean Water Act and the Montana Water Quality Act which require states to:

  • Assign designated uses to waters and develop water quality standards to protect those uses;
  • Monitor and assess water quality;
  • List impaired waters that do not meet standards;
  • Identify pollutant sources and set pollutant-reduction goals needed to achieve standards.

DEQ uses available data to assess water quality based on established water quality standards and reports on the status and trends of water quality every two years in Montana’s Water Quality Report and List of Impaired Surface Waters.

319 Project Funding

Through the 319 Project Program, DEQ provides approximately $1,000,000 each year to local watershed groups, conservation districts, educational institutions, and government entities to design and implement on-the-ground projects that reduce and prevent nonpoint source pollution. Increasingly, DEQ is focusing funding on projects that will restore natural processes (e.g., stream channel migration, floodplain connectivity, native riparian revegetation) and are likely to result in measurable improvements in water quality.

Check out the Interactive Projects Map to find out what we’ve been funding.

Applicant Eligibility:

Applicants must meet the following criteria:

  • Be a governmental entity or a nonprofit organization. A governmental entity is a local, state, or federal organization that has been established and authorized by law. Nonprofit organizations are identified as having a tax-exempt declaration of 501(c)(3) from the Internal Revenue Service.
  • Be registered with the Montana Secretary of State to do business in the state of Montana.
  • Have the necessary liability insurance, and be in compliance with the Workers Compensation Act.

Project Eligibility

Projects must meet the following minimum requirements:

  • Address nonpoint source pollution.
  • Implement actions consistent with recommendations in the current Montana Nonpoint Source Management Plan.
  • Implement activities or practices identified in a DEQ-accepted Watershed Restoration Plan
  • Address impairments identified on Montana’s 2020 List of Impaired Waters. In some instances, projects on streams that are not listed as impaired may be acceptable. These projects must reduce pollutant loading to an impaired, downstream receiving water OR protect existing uses from becoming impaired.
  • Be completable within three years. (Note: In some instances, sponsors may be encouraged to apply for funding for design and permitting, and then come back and apply for funding for actual construction in a subsequent year.)
  • Projects addressing stream flow through improved water use efficiency must include reasonable assurance that unused water will remain in the stream (e.g., through a change of use to instream flow, or a signed commitment from the water right holder).
  • Projects involving grazing management (e.g., riparian fencing, creation of riparian pastures) must include a grazing management plan as a task deliverable.
  • Projects involving riparian or wetland buffer creation must have a minimum buffer width of 35 feet, as measured from the water’s edge. If the buffer must be less than 35 feet in some places to accommodate bridges, water gaps or other infrastructure, the buffer should be made proportionately wider in other areas.
