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