Progress and Results:
Sand dredging is an invasive procedure, which removes sediment directly from the river bed and can disturb fish communities and geomorphic processes with in the river. We are investigating the role these potential habitat alterations play in the structure of fish communities and habitat availability within the Kansas River. Starting in summer of 2010 fish and habitat data (i.e., depth, water velocity, temperature) were collected monthly from 1 km dredged and undredged reaches. Preliminary analyses have revealed that dredged reaches have a higher proportion of deep water habitat (>3 m) than reaches not dredged. However, there are no significant differences in catch per unit effort of fishes between dredged and undredged reaches, although further analyses are needed to determine if these trends hold throughout the seasonal sampling.
