Water Availability. BLM is not aware of any decreed surface diversions in this reach. This
stream has never been gauged. BLM recommends using the Badger Creek lower station near
Howard for water availability calculations, with adjustments made to reflect the different sizes of
the watersheds.

Relationship to Management Plans. BLM has acquired significant acreage for public access
along Thirtyone Mile Creek as part of plan to block up public lands in this area. In addition,
BLM has implemented actions to improve fishery and riparian habitat along the creek. Because
the creek has public access at several points, it has the potential to become a more heavily used
recreational fishery as stream conditions improve and fish populations expand.

The BLM requests that the Board recognize that this recommendation is based only upon the
minimum flows necessary to support cold-water fishery values. BLM may wish to work with the
Board and/or through the Colorado water rights system to appropriate flows to optimally protect
fish values and to protect other water-dependent values specified in BLM resource management
plans.

Data sheets, R2Cross output, fishery survey information, and photographs of the cross section are
enclosed to support this recommendation. We thank both the Division of Wildlife and the Water
Conservation Board for their cooperation in this effort.

If you have any questions regarding our instream flow recommendation, please contact Roy
Smith at 303-239-3940.

Sincerely,
