Powder/Tongue River Basin Advisory Group
July 17, 2002
River Basin Planner Barry Lawrence welcomed the group and the meeting was
called to order at 5:58 p.m. Facilitators Cathy Lujan and Sherri Gregory-
Schreiner of Counterpoise were re-introduced to the group. 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 November 20 in Sheridan.
Water Development Commission Report
Barry Lawrence updated the BAG on the status of the plans for the other basins.
The BAGs for the Northeast Wyoming Basin will be meeting July 18 in Lusk, the
Wind/Bighorn Basin will be meeting August 13 in Worland and the Snake/Salt
Basin will be meeting August 14 in Moran. The Bear and Green River Basins
BAGs met July 15 and July 16 in Kemmerer. Barry discussed the status of all
basin studies, and schedule for future meetings.
Water Resources Data System Report
Robin Gray discussed the current drought situation. She indicated that weekly
drought e-mail updates are available, and can be requested via
email@example.com The Wyoming climate atlas is being updated and will be
available spring 2004. The 2002 Municipal Water Supply Survey has recently
been placed on-line. September 1, 2002 is the target date for the State
Engineer’s Office (SEO) groundwater rights database in queryable format to be
Goose Creek Watershed Awareness Project
Milar Stender explained that the project is an interactive information and
educational program, focused initially on youth, which utilizes informal field
settings combined with hands-on activities to investigate sources, impacts and
mitigation of non-point source pollution. For more information, a website is
available at www.gcwc.org
Aquatic Wildlife Resources in Northeast Wyoming (PDF Format - 4,793kb)
Bob McDowell, Wyoming Game and Fish Department, discussed the watershed
management plans in the Powder, Tongue, and Little Bighorn
basins. Sport fishing contributes $11.7 million annually to the area’s economy.
Bob indicated that fish management concepts include basic yield, trophy,
catchables, wild, and unique categories. 3,000 miles and 235 streams are
managed in the Sheridan region, of which 737 stream miles are located in
northeast Wyoming. He discussed the various non-game and game fish in the 4
basin drainages. The Yellowstone Cutthroat trout is the only species native to
the region. He discussed problems associated with nuisance fish introductions.
Other topics of discussion included habitat enhancement, access development,
amphibians, and aquatic habitat challenges.
Ranchester Level I Study/Dayton Water System Improvements (PDF Format - 4,038kb)
Dave Engels of EnTech, Inc. presented water supply project updates for
Ranchester and Dayton. He indicated problem areas with the current water
system for Dayton include low pressure, undersized town mains, raw water
quality from the Tongue River, a manually operated and monitored system, and
an existing 10” pipeline from the water treatment plant to town is located under
the IXL Ranch reservoir. A Level I study, which was completed in 2000,
recommended the construction of new transmission pipelines, a new pump
station, and miscellaneous town mains to improve fire flows. The Level II study,
which was completed in 2001, recommended construction of a new infiltration
gallery beneath Tongue River, installation of variable speed drives on raw water
pumps through the water treatment plant, and installation of a SCADA system.
In 2002, the WWDC recommended the drilling of a Madison Formation well as an
alternative water supply and a feasibility study of a regional water system for
Ranchester and Dayton be conducted. The recommendations from the Level II
study are on hold pending the deep well study results.
Potential problems with the current system in Ranchester include raw water
quality from Tongue River, additional distribution storage needs, and emergency
power generation needs. A Level I study is currently underway, which should be
completed in the fall of 2002.
State Engineer’s Office Report
Pat Tyrrell, State Engineer, discussed the agency’s change in public water right
search policy and related training available during the summer and early fall. He
discussed the June 2002 Yellowstone River Compact tour. Additional discussion
topics included coal bed methane, drought issues, and instream flow.
Coal Bed Methane (CBM) Update
Mickey Steward, Coalbed Methane Coordination Coalition, discussed dust
abatement on roads impacted by CBM development in the five county area. The
Coalition has been assisting with an application to the Wyoming Department of
Transportation for funding of $1.5M to resurface critical stretches of county
roads, primarily in Campbell County, with gravel producing less dust.
The finalization of an Environmental Impact Statement for CBM development has
been delayed by 2-3 months due to public comment.
Modeling CBM Surface Water Impacts Using the Erosion Potential Modeler
Greg Wilkerson, University of Wyoming, described the research project. He
stated the objectives were to establish an erosion index for drainages in
Northeast Wyoming and produce an erosion index map compatible with ArcView
GIS. An equation was developed to estimate the change in the channel due to
the addition of coal bed methane discharge water. Study reaches included
Deadhorse Creek and Burger Draw in the Powder River basin. Greg stepped
through an EP Modeler demonstration. The results indicated the potential for
accelerated erosion in the Powder River basin.
Oil and Gas Commission Report
Don Likwartz, Director, indicated water production from coal bed methane wells
has gone from 8 million barrels of water/year in 1993 to 516 million barrels of
water/year in 2001. However, the total number of active drilling rigs has declined
30% in the last year. There are four agencies involved in CBM development:
State Engineer’s Office, Department of Environmental Quality, Oil and Gas
Commission, and the Bureau of Land Management. He went on to indicate that
types of discharge within the basin vary due to topography and water quality.
Coordination and education issues were also discussed. To date, 14,700 CBM
wells have been drilled. It is anticipated that the well development will be last 10-
15 years, utilize 250-325 drilling employees, and create a total of 1000-1300
There being no further business, the meeting adjourned at 9:25 p.m.
