Utah Lake Water Temperature

How Temperature Affects Fishing

Water temperature is the single most important factor in predicting fish activity at Utah Lake. As a relatively shallow lake (averaging about 9 feet deep), Utah Lake responds quickly to air temperature changes, warming faster in spring and cooling faster in fall than deeper reservoirs.

Cold Water (Below 50°F)

Fish metabolism slows dramatically. Walleye are the most active species in cold water, making them the primary target during late fall, winter, and early spring. All other species become lethargic and require slow, methodical presentations. Catfish and bass are nearly inactive.

Cool Water (50-65°F)

The transition zone. White bass begin their famous spawning run at 55°F. Walleye fishing remains excellent. Catfish start feeding more actively above 55°F. Bass begin moving shallow for spawn preparation around 60°F. This temperature range represents some of the best multi-species fishing of the year.

Warm Water (65-80°F)

Peak fishing season for most species. Catfish are at maximum activity. Bass are aggressive and feeding. White bass school in open water chasing shad. Even carp become very active for bowfishing and bait anglers. Night fishing becomes productive as daytime temps push past 75°F.

Hot Water (Above 80°F)

Fish become stressed and less active during the hottest part of summer, particularly during afternoon hours. Early morning, evening, and night fishing are far more productive. This is also prime time for algae blooms — always check the HABs advisory page before fishing.
