Size and Weight
Utah’s 2026 catch-and-keep record lists a nine-inch Bonneville Cisco weighing 3.2 ounces, about 22.9 cm and 90.7 g. This exceeds the 22 cm maximum total length in an older general summary. The weight is a recorded catch, not proof of an absolute biological limit. A common length is about 16.8 cm, or 6.6 inches.
Habitat and Natural Food
Cisco occupy open water and feed on small planktonic animals such as copepods and rotifers. Their depth distribution changes with temperature: during warmer periods, cooler water below the surface becomes especially important. A fixed depth does not describe their habitat throughout the year.
Spawning and Fishing
Shallow-water spawning concentrations support a distinctive dip-net fishery. That is a documented harvest method rather than a bait recommendation. Anyone planning to participate should check the current season and gear requirements.
A Lake-Specific Fish
Its natural distribution is restricted to Bear Lake. That narrow range distinguishes it from other fishes also called cisco. Records for a different cisco species do not establish additional Bonneville Cisco waters.
One Lake, Changing Depths
The lake is its entire native setting, but the fish do not remain at one depth. Seasonal temperature changes redistribute suitable habitat, while spawning brings concentrations toward the shallows. Both open water and shoreline areas matter to its life cycle.
