Geological Survey Water Data Reporls Major Water Rights Calls Water rights calls in the White and Yampa Basins occur only on internally controlled tributaries where irrigation demands can exceed stream flows, such as Bear River; Piceance Creek; Fortification Creek; and North, Middle and South Hunt Creeks. On the mainstems there historically has not been administration of water right calls and water has been available for appropriation. Groundwater use is minimal and there is no administra- tion of wells in the basins. Future administration of the Yampa and White may be affected by activities and projects in the Recovery Program for Endangered Fish. Source: Office of the Division 6 Engineer Stream and Lake Protection There are 132 instream flow segments totalling approxi- mately 704 stream miles in these basins. There are also 14 lakes with decreed natural lake levels. These decreed water rights are held by the CWCB to "protect the natural environment to a reasonable degree." The decreed flow or lake level for each of these instream flow segments and natural lakes is based on the flow or lake level required to maintain the water-dependent natural environment.
