Habitat Comments:The Meadow Valley Wash desert sucker occurs in suitable habitat in Meadow Valley Wash, Clover Creek, and portions of Condor Canyon. In Clover Creek and Meadow Valley Wash below the Clover Creek confluence, suitable habitat is dynamic because of frequent flood events and populations can be isolated because of ephemeral summer flows and water diversions. Sucker growth was measured in the Condor Canyon section of Meadow Valley Wash, with lengths ranging from 20-39mm in June. By September and into early October, fork lengths ranged from 31-39 mm. Desert sucker movement was, in one instance, shown to be over 1km in Condor Canyon (Jezorek 2011). Spawning related movement was detected in late March to early May.
