Book Description
The chemical, physical, and biological attributes of aquatic habitats associated with two Lower Mississippi River dike system pools were investigated from August 1985 to January 1986. The habitats included the dike pool at river miles (RM) 488.6 to 491.4, and the pool at RM 483.6 to 484.4. A discontinuous stretch of sandbar habitat bordering the two pools was also sampled for comparison, though at a lower level of effort. The larger pool received substantial inflow around the channelward end of the dike, and over low points in the dike, during the entire study. Sand and gravel sediments were common in the larger pool in all months. Water temperature, dissolved oxygen levels, pH, and conductivity were similar in all three habitats during all sampling periods. Chlorophyll A concentrations were relatively high only in September. The benthic macroinvertebrate assemblages found in sediment samples from the two pools were generally similar during both August and October. No substantial differences were noted between the fish assemblages of the two pools; the fish assemblage found in the river sandbar habitat was somewhat different. Hydroacoustics indicated that fish were widely distributed in all microhabitats in both pools. (fr).
