ABSTRACT
From June to September in 2004 and 2005, we sampled twice per week from the irrigation canal below the dam to determine entrainment of crappies (Pomoxis spp.) from Sherman Reservoir, Sherman County, Nebraska. The estimated total loss from the reservoir was about 1.0 million crappies per year. During both years more crappies were released during nighttime than daytime hours and there was a positive relationship between water discharge and the number of crappies collected. Furthermore, increase in water discharge over 8 m3/s significantly increased the density of entrained crappies.
