Abstract: | Several sediment parameters were examined in a 40 ha lake with a maximum depth of 9 m and in a 950 ha lake, 26 m deep, from May through October, 1977. Particle size was finer at the deeper stations than at the shallower stations in both lakes. Sediments of the shallow stations generally had a more even grain size distribution. Variation in percent organic carbon and phosphorus among stations of different depths was not significant. However, temporal variation of phosphorus was significant as values increased during summer. Kaolinite was the dominant clay particle in both lakes, but the sediments also included quartz, mica, montmorillonite, and a montmorillonite-vermiculite interlayer. Sedimentation rate was inversely related to depth in the larger lake, while variation among stations in the smaller lake was slight.Research supported with funds from the Office of Water Research and Technology and the Bureau of Reclamation |
