Truckee Meadows Regional Storm Water Management Program

The City of Reno, Washoe County, and City of Sparks share a Municipal Separate Storm Sewer System (MS4) discharge permit for the Truckee Meadows region. These three entities also have an Interlocal Agreement for watershed protection throughout the region. City of Reno acts as coordinator and administrator for the Truckee Meadows Regional Storm Water Permit Coordinating Committee, which has been dubbed the "Truckee Meadows Watershed Committee" (TMWC). On the Data Collection Sites map, data points are called out as the responsibility of the Truckee Meadows Watershed Committee.

The TMWC meets monthly, and monitors surface water quality in streams throughout the region quarterly per the Sample Analysis Plan. Storm events are monitored annually, to better understand water quality effects of urbanization and monitor first flush of pollutants leaving the land surfaces. See SAPs attached below.

Data collected under the various Sampling and Analysis Plans (SAPs) may be found here: http://www.truckeeriverinfo.org/resource/740.

The TMWC has also funded and contracted surveys for reporting as the "Tributaries to the Truckee River Watershed Assessment Reports" from 2005 to 2012, using Proper Functioning Condition evaluations to measure stream conditions.

The TMWC agencies also participated in the Truckee Meadows Coordinated Monitoring program, managed contracts and the grant providing assistance, and provided sampling maps, editing, and other activities.
The 2012 Sampling & Analysis Plan and 2013 Addenda include outfall locations which are not called out on the Sample Collection Sites Map above. The specific map for all TMWC sampling sites, including the outfall locations along the river, are mapped on the attachment below (OF and TRIB sites). More recently, Balance Hydrologics updated and authored a Truckee Meadows Sampling and Analysis Plan for the 2015 year beginning January 1, 2015 and ending September 30, 2015. While the TMWC were granted approval of changing from a calendar year monitoring basis to a water year basis, this 2015 year was shortened to transition to water year schedule. The 2016 water year SAP took affect October 1, 2015 through September 30, 2016, and is attached below.
