exclusive to appropriate and acquire instream Ilow and natural lake-level water rights. In order
to encourage olher entities 10 participate in Colorado's Instream Flow Program. the statue directs
Ihe CWCB to requesl im.lream llow recommendations from other state and federal agencies. The
Bureau of Land Management (BLM) recommended this scgmelll of First Anvil Creek to the
eweB for inclusion into Ihe Inslream Flow Program. First Anvil Creek is being considered for
inclusion into the Instream Flow Program because it has a natural environment that can be
presen.ed to a reasonable degree with an instream !low water right. The BL~1 is very interested
in protecling the streamJlows in this area because in November of 1997. the U.S. Congress
Iransferred management of Ihe Navel Oil Shale Reserve from the Departmenl of Energy 10 the
BL~1. Congress directed the BlM 10 manage the area for multiple uses. while simultaneously
protecting the area's unique resource values.
