The Bonneville cisco (Prospium gemmiferum), a small planktivorous whitefish, is an important part of the distinctive fish community of Bear Lake, Utah-Idaho. The Bonneville cisco plays a key role in the trophic structure by converting zooplankton to fish biomass and providing a major forage source for cutthroat and lake trout. Aspects of cisco feeding ecology studied include characterization of the zooplankton community composition and dynamics and cisco feeding habits and prey selection.
Composition and seasonal dynamics of the zooplankton community were determined for a fifteen month period during 1981-1982. The community was dominated by a calanoid copepod, Epischura …

Development by man through the last half century has caused a number of changes in Bear Lake. These changes include the diversion of Bear River water into Bear Lake, the pumping of lake water back into the river, and the building of breakwaters and other obstructions along the shore of Bear Lake.
The diversion of Bear River water into the lake has resulted in a yearly addition of an estimated 36,000 metric tons of calcium into the lake, which has caused the precipitation of an estimated minimum 90,000 metric tons of aragonite. The pumping of Bear Lake water back into …
