Green River Basin Advisory Group
Meeting Record
Rock Springs, WY
March 25, 2003

Facilitator Sherri Gregory welcomed the group and the meeting was called to order at 10:04 a.m. All attendees introduced themselves, followed by a review of the overall meeting agenda. A sign-in sheet was passed around to record attendance. The next meeting is scheduled for July 8 at the Seedskadee National Wildlife Refuge.

Water Development Commission Report
Barry Lawrence updated the BAG on the status of the plans for the other basins. The BAG for the Snake/Salt Basins will be meeting March 26 in Alpine, whereas the BAGS for the Wind/Bighorn, Powder/Tongue and Northeast Wyoming Basins will be meeting April 1 in Cody, April 2 in Buffalo and April 3 in Newcastle. The Bear River Basin met March 24 in Cokeville. Open houses for the Platte River Basin will be held this spring. Barry discussed the status of all basin studies, and agenda for future meetings.

John Jackson indicated that four new commissioners had been appointed, including Dan Budd in Division IV. Nineteen new projects were authorized in the Omnibus Water Bill – Planning, including the Bridger Valley Reservoir project study. Twenty-seven projects were authorized in the Omnibus Water Bill – Construction. The two in this basin included the Big Piney Water Supply project, which will add new storage, and a connecting pipeline to Marbleton and the rehabilitation of the Jon’s Drop and Four Mile Flume in the Little Snake River drainage. The Groundwater Exploration Grant Program, which was amended in 2002, was appropriated an additional budget of $1,500,000. Eligibility for the Small Water Project Program was amended to include the entire state.

Upper Green River Joint Powers Board Update
Randy Bolgiano, Green River BAG member, indicated that Sweetwater, Sublette and Lincoln Counties have signed the joint powers water board formation paperwork. Carbon County has withdrawn and Uinta County has not signed at this time. The document has been submitted to the State of Wyoming Attorney General’s Office for review. Each of the three counties will appoint three members to the joint powers board. Discussion followed.

Instream Flow Issues (1320kb PDF) & Filings in Green River Basin(Part 1 - 1580kb PDF)
                                                                (Part 2 - 4303kb PDF)
Tom Annear, Wyoming Game and Fish Department (WGFD), indicated that instream flow is beneficial in that it maintains a quality of life, is an important economic factor in tourism and is a legal tool for the State of Wyoming to protect a beneficial use of water. The goals are to either maintain existing flow patterns and habitat on public lands or to restore or improve flow patterns and fishery habitat on private property. The process to obtain an instream flow right has science, public involvement and legal/institutional components. These involve various state agencies, the public, and various state and federal laws.

Paul Dey, WGFD, indicated that of the 83 statewide Instream flow segments filings, 35 segments, covering 145 miles, were located in the Green River basin. Priority dates range from 1989 to 2002. The State Engineer has approved 2 of the basin’s instream flow rights. Paul described each segment’s habitat. Discussion followed.

Wyoming’s Drought
Jan Curtis, State Climatologist, introduced the drought website and drought related links, which included the palmer index, soil moisture and Snotel maps. Most of the state is in an exceptional drought, but due to recent snowstorms, most of the state, has been upgraded to an extreme drought. As of March 24, 2003, the average snowpack in the Bear River basin was 85%. He emphasized the importance of precipitation in April for the basin. A brief discussion followed

Instream Flow Issues and Filings in the Green River Basin (Cont’d)
The Green River Basin BAG asked to continue the discussion with Wyoming Game and Fish representatives regarding the methodology utilized to review Instream flow applications before being submitted to the WWDC. Discussion centered on Wyoming Game and Fish Department staff versus Wyoming Game and Fish Commissioner roles.

Tree-Ring Based Reconstructions of Precipitation Variability in Southwest Wyoming over the Past 750 Years (413kb PDF)
Steve Gray, University of Wyoming, indicated that almost all water-resources planning is based on the climate of the past 100 years due to the instrumental records only covering that timeframe. This timeframe may not adequately reflect long-term trends and cycles. However, tree-ring archives provide long duration records. In this area, 174 trees were used in the study, which included pinon and limber pines. The reconstructed precipitation from the tree ring samples indicated that past centuries point to droughts being more pronounced and longer in length. In assessing the instrumental record for the 20th century, it appears that droughts were relatively short with unusually wet conditions in contrast to earlier timeframes. A lengthy discussion followed.

State Engineer's Office Report (Part 1 - 1445kb PDF)     (Part 2 - 1055kb PDF)
Pat Tyrrell and John Shields provided an update on Colorado River programs and issues. These included:

Discussion followed.

CBM Water Quality Applications to Surface Use
Mickey Steward, Coalbed Methane Coordination Coalition, indicated that the Atlantic Rim, Hanna and Seminoe areas had the most potential for coalbed methane (CBM) development in the basin. The coal is deeper in southwest Wyoming than in the Powder River basin and there will be different issues with the development of CBM in this area, including wildlife management issues, snow and wind related impacts in the winter, and more extensive road development and related dust control issues. Mickey discussed some of the concerns that evolved from CBM development in northeast Wyoming, including the various types of discharges, infrastructure needs, and water quality. Mickey noted that CBM water should be seen as a resource, to be used potentially as a source for stock watering and irrigation, or potentially for a controlled grazing system. A lengthy discussion followed.

The meeting adjourned at 3:44 p.m.
