  • SJRIP & PRRIP have similar partnerships.
  • Overview of the UCREFRP as an example.
  • SJRIP & PRRIP have similar partnerships.
  • Here are the four beautiful long-lived, big-river, warmwater endangered fish The Colorado pikeminnow , is the largest “minnow” in North America. Historically, reached 6 feet long They were sometimes called “Colorado River salmon,” of the Colorado river. The razorback sucker 3 feet, and living up to 40 years or more. The humpback chub with pronounced hump can grow up to 19 inches long and is typically found in canyon-bound reaches. The bonytail can grow up to 20 inches long and live as long as 50 years. Historically, these fishes occurred throughout the warmwater reaches of the basin from Wyoming to Mexico
  • The threats to the endangered fish populations are the many changes to their habitat: Hundreds of dams river flows have been cut by about a third Introduced nonnative fish
  • The recovery programs continue to demonstrate tangible, on-the-ground success in providing river flows, restoring habitat, constructing and operating fish ladders and screens, producing and stocking endangered fish, and monitoring results.

      • Choices
      • Enforce the ESA and escalate the conflict
      • File lawsuits
      • Seek amendment to the Endangered Species Act
      • Seek exemptions from the ESA
      • Identify the facts and negotiate a solution
      Upper Colorado River Basin: In the mid 1970s, U.S. Fish and Wildlife Service determined that any further depletion of water from the upper basin would result in jeopardy to endangered fish.

    • 7. Flow protection
      • Modified operation of Federal dams/ reservoirs
      • Leases & contracts
      • Improved efficiency of irrigation systems
      • Cooperative reservoir operations
      • Partnered in a new water storage project (Elkhead)

    • 8. Year-round protection of flows in Reach 2
    • 9. The Green River Reaches
    • 10. ESA Compliance on the Green River
      • In Utah some 200 water projects depleting nearly 600KAF/year have received ESA compliance under the Recovery Program.
      • 54 of those projects have been small depletions averaging less than 100 af/year. Some larger depletions include oil and gas projects, Green River Farms (currently under consultation) and some on the Duchesne River
    • 11. Some one here could have a depletion that the Recovery Program is covering
    • 12. Green River Policy 1994
      • Flows protected Reach 2 from FG to the Duchesne
      • Post Nov 1994 WR Approvals subordinate to bypass of fish flows – Summer and Fall
      • Annually select target 1,800-1,100 cfs for Summer
      • Annually select target 2,400-1,100 cfs for Fall
      • Measure targets at Jensen UT
      • 20 cfs set aside for critical needs with priority over fish flows

    • 16. Reach 2: Spring Peak Flows
      • Accomplish: in-channel maintenance
      • Green River synchronized to Yampa River Peak
      • Inundate floodplain in Ouray area for 2 weeks in 4 of 10 years
      • Greater than 18,600 cfs connects to backwater
      • Bankfull flows in 1 of 2 years
    • 17. Maintenance of Channel Complexity and connectivity
    • 18. Backwaters provide warm, food-rich areas to grow and condition young Razorback suckers and Colorado pikeminnow
    • 19. High flows remove algae and silt, rework spawning substrates, prevent channel narrowing
    • 20. Reach 2: Winter Flows
      • Accomplish: a stable environment for young fish, it is assumed that native fish (old or young) feed when the water is near freezing, therefore it's best if they expend as little energy as possible, i.e. don't have to go searching for a different habitat due to fluctuating flows.
    • 21. Reach 3: measured at USGS gage near Green River, Utah
      • Spring Peaks ≥ 39,400cfs to 8,300 cfs
      • Summer through Winter base flow 4,700 cfs to 1,300 cfs
      • Flooded off-channel habitats will benefit young Colorado pikeminnow and razorback suckers in lower Reach 3 and humpback chub in Desolation and Gray Canyons.
