Maximum monthly summer water temperatures before (2001) and after (2003) miles of rhannel ;:tnirtinn The habitat survey on Nevada Spring Creek focused on measuring pools, riffles, and substrate composition on the restored sections of the spring creek. The survey began at the spring source (mile ) and proceeded downstream to mile , randomly selecting a pool (1-4) and measuring every fourth pool and preceding downstream riffle. Pool measurements include: total pool length, maximum pool depth, riffle crest depth, and wetted widths at the pools maximum depth and the riffle crest. The difference between maximum pool depth and riffle crest depth was used to calculate residual pool depth. Sinuosity, valley slope and channel slope were measured with GIS using USGS digital orthophotos. Two modified Wolman pebble counts were implemented (miles and ) to determine substrate composition. Pool parameter data was summarized based on mean dimensions. Objective for Nevada Spring Creek habitat survey were to provide an assessment of quality of post-restoration pools and substrate composition, and to provide a baseline for future monitoring efforts.
