Meeting Minutes
April 19, 2005


The meeting was held at the Wyoming Fish and Game Building in Green River, WY (351 Astle Avenue, 307-875-3223). Attendees are listed below.

Purpose of Meeting:

The purpose of operation meetings (held in April, and August) is to inform the public and other interested parties of Reclamation's current and future operational plans and to gather information from the public regarding specific resources associated with Fontenelle Reservoir. In addition, the meetings are used to coordinate activities and exchange information among agencies, water users, and other interested parties concerning the Green River.


Meeting began at 10:00 a.m.

Fontenelle Hydrology

Presentation by Greg Smith, Green River Basin River Forecaster for the Colorado Basin River Forecast Center. Greg described the process used by the CBRFC for estimating inflows to reservoirs. Data used for Fontenelle forecasts range from 1973 to 2002 which gives a limited view of possible inflows to Fontenelle. Fontenelle forecasts are particularly challenging due to a lack of data. Upstream private reservoirs do not provide adequate operational data. High elevation snowpacks are not gauged. Diversions and depletions from river for agriculture are not adequately measured.

Presentation by Rick Clayton: Hydraulic Engineer for Fontenelle and Flaming Gorge for the Bureau of Reclamation. Rick described the current conditions of Fontenelle. Current space in Fontenelle is 204,900 acre-feet and the reservoir is 31.32 feet from full. Releases have been increased to powerplant capacity. Based on the forecasted inflows for this year Fontenelle will likely fill this year and bypass releases will be necessary to manage reservoir elevations. Current release plans show a total release in mid to late June and early July that could reach 4500 cfs as a maximum. Fontenelle Reservoir should be very nearly full by early August of 2005.

General Discussion

R. Keith of WFG is concerned about sediment build up in river channel resulting for no high flows for 5 years. R. Keith requests that flows higher than 4500 cfs be made this year based on some test flow results he has seen on the Platt River. C. Damberg from Seedskadee Wildlife Refuge agreed with R. Keith on the need for high flows. B. Seppie for JPWB indicates that high flows increase turbidity of water and makes their operation more difficult and expensive but can agree to the high flows as long as notice can be given to JPWB.

R. Keith wants summer, fall flows at 1000 cfs if possible. Discussion of kayak flows did occur. Reclamation stated that it would not lower flows during spring runoff to accommodate kayak events. E. O’Neall from GR Chamber did not indicate that a reduction would be requested in the spring. Reclamation indicated that the fall event may be able to be taken care of by maintaining powerplant capacity to the end of August. Reclamation will try to do this if water is available.
