     Lahontan Dam and Reservoir
              Newlands Irrigation Project




•   Dam - 120 feet high by 1,300 feet wide
•   Reservoir 23 miles long, covers 100,000 acres
•   Provides water for farming in Churchill and Lyon Counties
•   Largest structure of the Newlands Project

  Current Water Situation
• River is fully appropriated
  – 95 %+ of the river water is used for Ag
• Groundwater basins over appropriated
• Balancing water needs between Ag,
  environmental & domestic use
• No large upstream storage
• Water quality problems
• Growth

                  Drought



• Defined as 70% or less of average annual precipitation
• Affects water quality and habitat
• Multi-year droughts occur about every 10-15 years
  in the Carson River Watershed
• Drought occurred in the years of 1981, 1987, 1988,
    1990, 1991, 1992, 1994 and 2001

  U.S. EPA Watershed Framework
• Hydrologically defined
• Involves all stakeholders
   – Includes public and private sector
   – Community based
   – Includes coordinating framework
• Strategically addresses priority water resource goals
  (e.g. water quality, habitat, industrial & municipal)
   – Integrates multiple programs (regulatory & voluntary)
   – Based on sound science
   – Aided by strategic watershed plans
   – Uses adaptive management
        EPA Seven-Step Process
• Build partnerships       •   Develop Watershed
• Characterize the             Plan
  Watershed                •   Implement the
• Set goals and identify       Watershed Plan
  solutions                •   Measure Progress and
• Design an implementation     Make Adjustments

 Benefits of Integrated
Watershed Management
      Approach

•   Shared vision & goals
•   Connects groups
•   Support and direction for on-the-ground projects
•   Consistency throughout watershed - planning & projects
•   Additional resources for everyone
•   Leverage funding
•   Increase in overall stewardship of resources
            Regional Programs




Formally adopted in 2008 by            Meets EPA 319 criteria for

River Rehabilitation
Bio-Engineering techniques to reduce erosion
Native plant materials, very little rock, natural
recruitment
Use willow bundles,
erosion control
mattresses etc., to
stabilize banks.
Incised banks are laid
back and re-connected
to floodplain
  Regional Floodplain Management Plan
• Suggested Actions Categories
  – Protect Floodplain Natural Functions & Values
  – Higher Regulatory Standards
  – Flood Data Information and Management
  – Channel Migration and Bank Erosion Monitoring
  – Floodplain & Flood Hazard Outreach and Education
  – Reduce Infrastructure Impacts

               Management Program
               – Protect and restore

               – Control sediment and
                 other non-point source

               – Outreach and
                 Education
        What Have We Learned?
• Watershed approach works-involve community
  members, reduce conflict
• The river is the resource
• Use non-structural approach
• Need consistent source of funding
• Regional cooperation is critical
Thank You!!!
