The objectives of this portion of the L-Lake/Steel Creek Biological Monitoring Program are to evaluate the impact of L-Reactor operations on the structure of the periphyton community and on the quantity, quality, and size-distribution of seston in the stream, delta, and swamp of Steel Creek. The temporal trends in periphyton biomass (chlorophyll a concentration) on sediments and wood substrates at all Steel Creek sites appeared to be within the range of natural variability. Canonical discriminant analysis, a multivariate statistical technique, revealed that the Steel Creek corridor sites (Stations 275, 280, 285 and 290) were less similar in 1987 than in 1986 with respect to certain periphyton parameters (dry mass, ash-free dry mass, and chlorophyll a). Conversely, sites at the other downstream locations (delta, swamp, and channel) were more similar with respect to these parameters in 1987. On slide and sediment core substrates, periphyton biomass was generally higher in the corridor than at other Steel Creek sites. 87 refs., 55 figs., 33 tabs.
