  • Regional Water Planning Commission Washoe County Department of Water Resources 4930 Energy Way Reno, NV 89502 Tel: 775-954-4665 Fax: 775-954-4610 Purpose: The purpose of the Comprehensive Regional Water Management Plan (Regional Water Plan) is to provide the region with an outline of how water will be managed to meet the needs of the citizens into the future. Major components of the plan are identification of future water supply and wastewater facilities, regional flood control and drainage projects, and development of a water conservation program.
  • The Truckee River watershed consists of several named and unnamed tributaries that flow through urbanized areas within the Truckee Meadows. Detailed assessments of these tributaries were first performed in 2002 to support development of a Watershed Management and Protection Plan, which was prepared jointly by the Washoe County Department of Water Resources, the University of Nevada Cooperative Extension, and the Washoe‐Storey Conservation District. The initial watershed assessments provided a broad range of valuable information, and it was determined that they should be performed annually to evaluate impacts from development and track trends in stream condition and overall stream health. Since 2005, The Truckee Meadows Storm Water Permit Coordinating Committee (SWPCC) has implemented a Watershed Assessment Program for tributaries to the Truckee River. Funding for the program is provided by the City of Reno, City of Sparks, Washoe County, the Nevada Department of Transportation (NDOT), and the Western Regional Water Commission (WRWC). Tributary assessments were performed annually from 2005 to 2012 under direction of the SWPCC, but did not occur during 2013 or 2014 due to budgetary constraints. Tributary assessments were again performed in 2015, and the results of these assessments are presented in this report. The organization and approach, stream assessment procedures, Geographic Information System (GIS) database, and a summary of impaired waters are discussed in this section. Assessment results for the Peavine, North Carson Range, Southwest Truckee Meadows, and North Truckee Drain Watersheds are presented in Sections 2‐5, respectively.
  • This is a Technical Memo produced in February 2013 by Jeff Curtis, Ph.D. at Stantec's Reno office. Associated with the Truckee Meadows storm water permit coordinating committee. This report addresses fundamental questions in background vs. storm water influences on water quality in regional tributaries, as a method of focusing monitoring efforts in the most proper direction possible. This report was funded by the SWPCC and the Western Regional Water Commission.
  • The objective of this project is two-fold; to develop a benthic macroinvertebrate multimetric index using existing data to apply to the main stems of the rivers of west central Nevada (the Truckee River, the Carson River, and the Walker River) and to evaluate physical habitat measurements for the main stem of the Truckee River as a potential assessment tool
  • This document describes a fish assemblage IBI for western Nevada rivers, and how it is applied it to the Truckee River.
  • The objectives of the current activities were to determine if sufficient data was available to derive preliminary periphyton-based metrics that could be used in a periphyton-based indices of ecological condition for the Lower Truckee River, which could in turn be used to derive more comprehensive indices of biological integrity (IBI) based on fish, macroinvertebrates and periphyton populations. Derivation of metrics and indices was made possible through the use of relatively recent (2000 to 2004) seasonal periphyton data that was collected from 11 to 15 locations from California-Nevada border to Pyramid Lake. Although, the levels of taxonomic information from the different data sets were not always comparable, several candidate metrics and indices encompassing information from both the species level and the genera level were identified, calculated and evaluated.
  • The objective of our analysis was to develop a biological index for benthic macroinvertebrates for the Nevada portion of the mainstem of the Truckee River using preexisting data. We analyzed data collected by four separate entities, Nevada Division of Environmental Protection (NDEP), Pyramid Lake Paiute Tribe (PLPT), Truckee Meadows Water Reclamation Facility (TMWRF), and Desert Research Institute (DRI).
  • The scope of the current study involved collecting another set of aquatic food web samples in March 2004 on the Truckee River for carbon and nitrogen stable isotope analysis. This report presents the methods and results of this sampling.
  • Amended by City of Reno in 2008. This plan is divided into nine sections: Introduction, Truckee River, Drainageways, Wetlands/Stream Environments, Geology and Soils, Geologic Hazards, Air Quality, Archaeological Resources and Historic Resources. The Introduction describes the boundary, time frame, relationship to other plans and why this plan is needed. Additional sections generally describe the conservation, development, and utilization of the natural resources identified. This Conservation Plan covers all of the City of Reno and its sphere of influence at the time this plan was prepared. This Conservation Plan horizon is to the year 2030. This plan is an element of the City of Reno Master Plan prepared in accordance with Nevada Revised Statutes (NRS) 278.150 through 278.170. Policies of the Truckee Meadows Regional Plan are applicable regionwide. The City of Reno Master Plan has three different levels of applicability; Citywide, Center and Corridor, and Neighborhood. Citywide plans include this Conservation Plan and other plans that apply to the entire City and its sphere of influence. Center and Corridor plans are for the eight centers and five transit oriented development corridors in the City and its sphere of influence. Neighborhood plans cover other areas, not in centers or corridors, which have been designated as appropriate for more detailed planning. Policies in center, corridor and neighborhood plans elaborate, with greater detail, upon general policies contained in the citywide and regional plans. Center, corridor and neighborhood plans must conform with and not be in conflict with policy direction of the citywide plans and the Truckee Meadows Regional Plan. Similarly, Title 18 of the Reno Municipal Code applies at the citywide, center and corridor, and neighborhood levels and must be consistent with these plans.

  • US EPA Method for determining physical habitat conditions using method for assessments. This method is being used by PLPT in tandem with benthic macroinvertebrate sampling, to further describe the watershed and potential causes for impaired results in bmi populations.
  • This project is in progress through DRI, with Alan McKay as one of the PIs. This project was described as an exploration of watershed-specific nuances in algal growth/uptake that may differ significantly from previously held scientific beliefs based on growth in other river systems. Better science will make for more accurate modeling on these systems.
  • The factors controlling nitrogen availability, and hence algal productivity, in Pyramid Lake differ from those in the Truckee River, and therefore, an assessment of the impacts of water management strategies must reflect those differences. As a lake, algal production in Pyramid is affected by total available nitrogen from external sources, internal sources, and the nitrogen concentration of lake waters.
  • A hydrogeologic investigation was undertaken to characterize the groundwater system in the Fernley Basin and to determine the total dissolved solids (TDS) loading to the Truckee River between the towns of Wadsworth and Nixon. A groundwater flow and transport model was constructed to integrate all of the available data and to predict the potential loadings under various management alternatives.
  • Numerical models that simulate river temperature have come into common use by managers concerned with water quality (pollutant loading) as well as biological communities.
  • The major streams in Nevada have had TMDLs (Total Maximum Daily Loads) established for several years. While these TMDLs seem to satisfy the requirements of the Clean Water Act, they have contributed little to any watershed/waterbody assessment and restoration plans.
  • This document provides a description of data available to support water quality modeling in the Truckee River Basin (DSAMMt model). Conditions within the Truckee Basin have changed considerably throughout the 19th century (beaver importation, riparian tree removal, channelization, flow diversion for agriculture, flood control, Marble Bluff Dam, grazing, flow augmentation, riparian restoration, etc.). Future changes are expected associated with river operations, flood control, and channel restoration. Although it is one of the better studied rivers in the world, there are significant gaps in our knowledge of the system.
  • The Nevada Division of Environmental Protection is required by the Clean Water Act to conduct a comprehensive analysis of water quality data associated with Nevada's surface waters to determine whether state water quality standards are being met and designated uses are being supported. This integrated report provides snapshot conditions of all waters in the state of Nevada, impaired or otherwise.
