Vernal Instream Flow

Instream flow recommendations have been either completed, or are in some stage of approval, for all mainstem reaches and major tributaries of the Upper Colorado River Basin that support the ‘large river’ endangered fishes. Flow recommendations developed by the Vernal CRFP are being used by Fish and Wildlife Service Ecological Services staff to update biological opinions for the Yampa and Duchesne rivers. Data collected by the Vernal CRFP also contributed to the flow recommendations in the Green River and operation of Flaming Gorge Dam. Habitat enhancement in the Green River subbasin has emphasized instream flow needs and floodplain restoration. All flow recommendations are subject to state law and existing water rights.
