Washoe County Clean Water

Source Water Protection & Non-Point Source Management


The 2020 Integrated Source Water and 319(h) Watershed Protection Plan for Public Water Systems and the Truckee River in the Truckee Meadows (Plan) is a tool developed by our community to help preserve and improve the quality of groundwater, lakes, rivers, springs, and streams that supply drinking water to the general public. This voluntary multi-jurisdictional planning effort is organized on a watershed basis for the Truckee River through the Truckee Meadows. Because the river and local aquifers comprise the drinking water sources for most of the population of Washoe County, watershed management of non-point source pollution goes hand in hand in with protecting source water quality.

This website provides interactive maps and PDF documents, which together comprise the county-wide plan information.

Project Profiles

How to protect and improve water quality now and into the future?

See a summary of on-going and proposed actions!

These Project Profiles include the information needed, to the extent practical, as identified in the EPA guidance for the nine critical elements for an endorsable watershed management plan.

Strategies to protect and improve water quality were developed for watersheds and source water protection areas (SWPAs) to address water quality concerns. These strategies are combined in this section from the Watershed Profiles and the Watershed Management and Protection Plan for Tributaries to the Truckee River by the Truckee Meadows Stormwater Permit Coordinating Committee for ease of reference.

Watershed Committee

Truckee Meadows Stormwater Permit Coordinating Committee – The interlocal agreement between the Cities of Reno, Sparks, and Washoe County, updated in 2004, concluded that it was appropriate to expand the purview of the Truckee Meadows Storm Water Permit Coordinating Committee to include consideration of watershed management for the benefit of water quality in the Truckee River tributaries.
