Summary

The information contained in this report and the associated instream flow file folder for Second
Anvil Creek forms the basis for staff s in stream flow recommendation to be considered by the
Board. It is staffs opinion that the information contained is this report is sufficient to support
the findings required in Rule 5.40.

Colorado's Instream Flow Program was created in 1973 when the Colorado State Legislature
recognized "the need to correlate the activities of mankind with some reasonable preservation of
the natural environment" (see ~ 37-92-102 (3) c.R.S.). The statue vests the CWCB with the
exclusive to appropriate and acquire instream flow and natura1lak.e-Ievel water rights. In order
to encourage other entities to participate in Colorado's Instream Flow Program, the statue directs
the CWCB to request instream flow recommendations from other state and federal agencies. The
Bureau of Land Management (BLM) recommended this segment of Second Anvil Creek to the
CWCB for inclusion into the Instream Flow Program. Second Anvil Creek is being considered
for inclusion into the Instream Flow Program because it has a natural environment that can be
preserved to a reasonable degree with an in stream flow water right. The BLM is very interested
in protecting the streamflows in this area because in November of 1997, the U.S. Congress
transferred management of the Navel Oil Shale Reserve from the Department of Energy to the
BLM. Congress directed the BLM to manage the area for multiple uses, while simultaneously
protecting the area's unique resource values.

Second Anvil Creek is a tributary of East Fork Parachute Creek and is approximately 2.0 miles
long. It begins West of the Roan Cliffs, at an elevation of approximately 8860 feet, and
terminates at the confluence with the East Fork Parachute Creek, near Rifle, at an elevation of
approximately 8260 feet. It is located completely on federal lands (the Naval Oil Shale Reserve
which is managed by the Bureau of Land Management). It is located in Garfield County. The
total drainage area of Second Anvil Creek is approximately 1.8 square miles. Second Anvil
Creek generally flows in a northwest direction.

The subject of this report is a 2.0 mile segment of Second Anvil Creek beginning at its
headwaters and extending downstream to the confluence with East Fork Parachute Creek (see
Figure 1). This segment is located northwest of the City of Rifle. To date, staff has received and
considered only one flow recommendation for Second Anvil Creek. That recommendation is
discussed in detail below.
