| Abstract: | We examined microhabitat use among fishes in a 37 m section of Coweeta Creek, NC., over a ten-year period (1983-1992) that included both floods and droughts. Multivariate comparison using Principal Component analysis of fish use data was contrasted with habitat availability. |

| Methods/Experimental Design: | Fish and habitat measurements were done seasonally. Fish observational data was collected by snorkeling and recording data on an undisturbed fish. Depth, focal point water velocity, average water velocity, distance from substrate, distance to shelter, shelter type, and percent substratum composition within a 20 cm quadrat were recorded. Random habitat measurements were recorded within the site to then characterize the available habitat to the fish. Data measurements were the same used for the fish except for the exclusion of focal point water velocity, distance form substrate and distance to shelter. |
| Sampling Frequency: | Variable but classified seasonally. |
