Turnitin: Prosiding DFC 2017 - Can Treated Waswater Reestablish Aquatic Communities in Desert Rivers?

Abstract

The California Department of Fish and Wildlife (CDFS) conducted drought monitoring (stream flow and temperature) in three Redband Trout streams in the Goose Lake basin (Lassen, Cold, and Willow Creeks) that provide habitat for Goose Lake Redband Trout, Goose Lake Sucker, Goose Lake Lamprey, and Pit Sculpin) and six tributaries that provide habitat for Modoc sucker (Turner, Washington, Coffee Mill, Hulbert, Dutch Flat, and Johnson Creeks). Given a better water year, all streams appeared to be in good condition following the extreme drought conditions observed in 2014-2015. CDFW also collected tissue samples for genetic analysis of Eagle Lake Rainbow Trout (ELRT) to evaluate genetic diversity and inbreeding related to the effects of artificial propagation of this native strain and to evaluate genetic uniqueness of extant “resident” upper Pine Creek populations. Assessed spawning movements of 119 pit-tagged ELRT in Pine Creek and documented movement of two fish to the headwater spawning area. Conducted an assessment of Pine Creek headwaters for Brook Trout distribution and (planning) and ongoing removal efforts.
