Trout Creek Restoration (Truckee River watershed)

Trout Creek; channelized reach

Page 7: Tahoe Sierra Integrated Regional Water Management Plan (IRWMP) Presentation and Overview:

Water Conservation Program: Water Conservation Program: Turf Buy Back/Native Landscape Turf Buy Back/Native Landscape ProjectProject

Before: Property with lawn and inefficient landscape irrigation

After: Property with native plant, low water landscape installation

Decrease in water usage

Decrease pumping, treatment and transporting water supply

Decrease in stormwater runoff, fertilizer and energy usage

Project is a BMP under the California Urban Water Conservation Council

TMDL Water Quality Monitoring for Truckee River (TR)

Truckee River watershed 303(d) listed Targets suspended sediment Monitoring needed to prioritize TMDL

implementation 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

Page 9: Tahoe Sierra Integrated Regional Water Management Plan (IRWMP) Presentation and Overview:

Lake Tahoe Unified School District BMP Implementation

School District located in disadvantaged community

Mitigation of large developed areas and installation of best management practices that will mimic natural hydrologic processes

Assists in preservation of 303d Impaired Water body through reduction in pollutant loading, specifically fine sediments and nutrients

Benefits and Technical Feasibility

Community members and school childrenparticipate in BMP presentation to increase awareness on local naturalresource issues.

Benefits and Technical Feasibility

Lake Tahoe TMDL BMP Implementation

Current focus on Large Multi-family and Commercial Properties New Phases: Single Family Residential Enforcement, Expanded Outreach Campaign New Project: Update Real Estate Community BMP Status Disclosure

Asphalt removal on MFR Installation of a rock/veg infiltration swale

Truckee River (TR) Voluntary BMP Retrofit

Need and Consequences

TR is 303(d) listed for suspended sediment TMDL lists stormwater and legacy issues as

priority sediment sources Tahoe Donner and Donner Lake

subdivisions: erosive soils, steep slopes, high % lot coverage; high density building

Poor infiltration and source control from residential sites

Example from another program:

Increased infiltration, source control, via vegetation, and runoff and drip line capture

Page 12: Tahoe Sierra Integrated Regional Water Management Plan (IRWMP) Presentation and Overview:

Water Supply Pipeline Replacement:Water Supply Pipeline Replacement:

Before: Aged, deteriorating lines

After: Replacement water lines and main lines

Decrease in water loss through leakageIncrease in fire protection, water pressure and availabilityProject is a BMP under CUWCC

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

Page 14: Tahoe Sierra Integrated Regional Water Management Plan (IRWMP) Presentation and Overview:

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

Benefits for Implementation of Project Components
