Slide 4

Colorado pikeminnow Ptychocheilus lucius Razorback sucker Xyrauchen texanus Humpback chub Gila cypha Green River is imperative stream for recuperation on account of the surge plain living space, there are 2 bringing forth populaces of Co pikeminnow and most obvious opportunity for razorbacks Bonytail Gila elegans

Slide 5

Threats: Large Water exhaustion supplies Fish hindrances Nonnative fish

Slide 6

Managing Nonnative Fish Research and Monitoring Stocking Endangered Fish Recovery Elements Habitat Development Habitat-Flow Management

Slide 7

Flow security Modified operation of Federal dams/repositories Leases & contracts Improved proficiency of water system frameworks Cooperative repository operations Partnered in another water stockpiling venture (Elkhead) Elkhead Reservoir

Slide 8

Year-round assurance of streams in Reach 2

Slide 9

The Green River Reaches

Slide 10

ESA Compliance on the Green River In Utah about 200 water ventures draining almost 600KAF/year have gotten ESA consistence under the Recovery Program. 54 of those tasks have been little exhaustions averaging under 100 af/year. Some bigger exhaustions incorporate oil and gas ventures, Green River Farms (at present under conference) and some on the Duchesne River

Slide 11

Some one here could have a consumption that the Recovery Program is covering

Slide 12

Green River Policy 1994 Flows shielded Reach 2 from FG to the Duchesne Post Nov 1994 WR Approvals subordinate to sidestep of fish streams – Summer and Fall Annually select target 1,800-1,100 cfs for Summer Annually select target 2,400-1,100 cfs for Fall Measure focuses at Jensen UT 20 cfs put aside for basic needs with need over fish streams

Slide 13

Table 5.5.— Flow and temperature suggestions by hydrologic condition for Reach 2 (Yampa River to White River) to profit imperiled angles in the Green River downstream of Flaming Gorge Dam. a

Slide 16

Reach 2: Spring Peak Flows Accomplish: in-channel support Green River synchronized to Yampa River Peak Inundate floodplain in Ouray range for 2 weeks in 4 of 10 years Greater than 18,600 cfs associates with backwater Bankfull streams in 1 of 2 years

Slide 17

Maintenance of Channel Complexity and network

Slide 18

Backwaters give warm, nourishment rich territories to develop and condition youthful Razorback suckers and Colorado pikeminnow

Slide 19

High streams expel green growth and sediment, revise producing substrates, avoid channel narrowing

Slide 20

Reach 2: Winter Flows Accomplish: a steady domain for youthful fish, it is accepted that local fish (old or youthful) bolster when the water is close cold, subsequently it\'s ideal on the off chance that they exhaust as meager vitality as would be prudent, i.e. try not to need to go scanning for an alternate living space because of fluctuating streams.

Slide 21

Reach 3: measured at USGS gage close Green River, Utah Spring Peaks ≥ 39,400cfs to 8,300 cfs Summer through Winter base stream 4,700 cfs to 1,300 cfs Flooded off-channel natural surroundings will profit youthful Colorado pikeminnow and razorback suckers in lower Reach 3 and humpback chub in Desolation and Gray Canyons.
