Idaho §305(b) Lakes, Lakes Designated with Waterbody IDs, Beneficial Uses, Support status for the Current Clean Water Act (CWA) reporting year. Based upon 100k NHD Hydrography and DEQ's WBIDs. Idaho 2016 305(b) & 303(d) Integrated Report - Water Quality. Every two years, DEQ is required by the federal Clean Water Act to conduct a comprehensive analysis of Idaho's water bodies to determine whether they meet state water quality standards and support beneficial uses or if additional pollution controls are needed. This analysis is summarized in an "Integrated Water Quality Monitoring and Assessment Report" (Integrated Report), which is submitted to the U.S. Environmental Protection Agency (EPA) for approval. The report serves as a guide for developing and implementing water quality improvement plans (total maximum daily loads, or TMDLs) to protect water quality and achieve federal and state water quality standards. The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that comprise the nations surface water drainage system. It is based initially on the content of the U.S. Geological Survey 1:100,000-scale Digital Line Graph (DLG) hydrography data, integrated with reach-related information from the U.S. Environmental Protection Agency Reach File Version 3.0 (RF3). More specifically, it contains reach codes for networked features and isolated lakes, flow direction, names, stream level, and centerline representations for areal water bodies. Reaches are also defined to represent waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans, and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria set out by the Federal Geographic Data Committee.
Sections 305(b) and 314 of the Clean Water Act (CWA) require states, territories, and authorized tribes to provide biennial reports to EPA on the condition of waters within their boundaries. EPA regulations at 40 CFR 130.7 require states to provide biennial submissions of impaired waters lists. EPA provides guidance on these reports in a way that supports the Agency's strategy for achieving a broad-scale, national inventory of water quality conditions. The guidance is from EPA to states, territories, authorized tribes, and interstate commissions ("jurisdictions") to help states prepare and submit Section 305(b) reports to EPA. Use of the integrated report (IR) format provides jurisdictions a recommended reporting format and suggested content to be used in developing a single document that integrates the reporting requirements of Sections 303(d), 305(b), and 314. This format allows jurisdictions to report on the water quality standards attained for all waters, document the availability of data and information for each segment, identify certain trends in water quality conditions, and set priorities for protecting and restoring the health of the nation's aquatic resources. Section 305(b) of the Clean Water Act requires each state to conduct water quality surveys to determine a water body's overall health, including whether or not basic uses are being met. States, tribes, and other jurisdictions define appropriate uses for a waterbody and incorporate these uses into water quality standards that are approved by EPA. Water body uses include aquatic life protection, fish and shellfish production, drinking water supply, swimming, boating, fishing, and agricultural irrigation, among others.

This dataset contains Montana’s rivers that have been identified for monitoring and assessment by the Montana Department of Environmental Quality’s Water Quality Planning Bureau. Rivers are assessed for water quality per the federal Clean Water Act and the Montana Water Quality Act (MCA 75-5-702). Pollutants and pollution identified as impairing Montana’s assessed rivers are contained in in the dataset and listed in Montana’s 303(d) list.
The IR and the 303(d) list may be viewed at: http://deq.mt.gov/Water/WQPB/cwaic/reports.
The geometry of the rivers is based on the 1:24,000, High Resolution NHD, v. 2.2.
