Tahoe Sierra Integrated Regional Water Management Plan IRWMP

Tahoe Sierra Integrated Regional Water Management Plan (IRWMP) Presentation and Overview: June 2013

Tahoe Sierra IRWM Overview: who does group represent? Location and boundaries of Tahoe Sierra IRWM Status of prop 50 projects Legend Major Roads Regional Boundary Project Watersheds: East Fork Carson River Lake Tahoe Little Truckee River West Fork Carson River Lake Tahoe **Disadvantaged Communities: Miles Kings Beach South Lake Tahoe

Tahoe Sierra Integrated Regional Water Management Goals: • Foster a collaborative water management planning • • • environment; Promote integration of water management across geographies of the region; Recommend priorities for implementation projects; Cooperatively apply for and obtain funding for implementation projects; Revise and update the Tahoe Sierra IRWM Plan as needed; and, Communicate the best available information to decision makers, stakeholders and the public.

Trout Creek Restoration (Truckee River watershed) Trout Creek; channelized reach

Water Conservation Program: Turf Buy Back/Native Landscape Project ØDecrease in water usage ØDecrease pumping, treatment and transporting water supply ØDecrease in stormwater runoff, fertilizer and energy usage ØProject is a BMP under the California Urban Water Conservation Council Before: Property with lawn and inefficient landscape irrigation After: Property with native plant, low water landscape installation

TMDL Water Quality Monitoring for Truckee River (TR) Ø Truckee River watershed 303(d) listed Ø Targets suspended sediment Ø Monitoring needed to prioritize TMDL implementation Ø Monitoring required to assess effectivness of TMDL Coldstream Canyon: Severely eroded streambank sending tons of fine sediment into the TR each year; no monitorig Negro Canyon: road capture of Gregory Creek, Dec 2006; high turbidity loads, no monitoring of this event

Lake Tahoe Unified School District BMP Implementation Benefits and Technical Feasibility ØSchool District located in disadvantaged community ØMitigation of large developed areas and installation of best management practices that will mimic natural hydrologic processes ØAssists in preservation of 303 d Impaired Water body through reduction in pollutant loading, specifically fine sediments and nutrients Community members and school children participate in BMP presentation to increase awareness on local natural resource issues.

Lake Tahoe TMDL BMP Implementation Benefits and Technical Feasibility Asphalt removal on MFR Ø Current focus on Large Multi-family and Commercial Properties Ø New Phases: Single Family Residential Enforcement, Expanded Outreach Campaign Ø New Project: Update Real Estate Community BMP Status Disclosure Installation of a rock/veg infiltration swale

Truckee River (TR) Voluntary BMP Retrofit Need and Consequences Ø TR is 303(d) listed for suspended sediment Ø TMDL lists stormwater and legacy issues as priority sediment sources Ø Tahoe Donner and Donner Lake subdivisions: erosive soils, steep slopes, high % lot coverage; high density building Example from another program: Increased infiltration, source control, via vegetation, and runoff and drip line capture Poor infiltration and source control from residential sites

Water Supply Pipeline Replacement: ØDecrease in water loss through leakage ØIncrease in fire protection, water pressure and availability ØProject is a BMP under CUWCC Before: Aged, deteriorating lines After: Replacement water lines and main lines

Benefits for Implementation of Project Components – Tahoe Sierra IRWM Water Quality - addresses non-point source pollutant loading from urban areas - necessary component related to TMDL development and requirements - helps to meets standards for Safe Drinking Water Act Ecosystem Restoration - restores historic stream channel and hydrologic conditions for benefits of human populations and fish/wildlife - serves as a natural filter to decrease pollutant loading into local waterbodies

Benefits for Implementation of Project Components – Tahoe Sierra IRWM Water Conservation & Water Supply - builds reliable infrastructure to supply water to urban and dis-advantaged communities - promotes water conservation measures and practices specifically related to AB 1420 Flood Control - reduces potential for property damage and health risks - retains and manages stormwater runoff for other beneficial uses Disadvantaged Communities - increases economic viability though implementation of project components - improves environmental degradation within disadvantaged community
