The lake, formed on Eocene lava, is oliotrophic and low in dissolved solids. Diatomus shoshone, Daphnia shoedleri, and Conochilus unicornis made up more than 90 percent of the macroscopic zooplankton by number. Upwelling in West Thumb was demonstrated by temperature stratification and conductivities. Plankton distribution and abundance were related to currents and water chemistry. Trout less than 315 millimeters in total length are not caught readily because of their feeding habits and greater dispersal. There is evidence that the heavy trout harvest in the northern part of the lake allowed Gammarus lacustris, an important food, to become locally abundant. |
