Ice often melts off the Enterprise reservoirs in February or early March. As the snow melts and the reservoirs fill, you can often expect the water to be murky or muddy. Hungry rainbow trout often provide good to excellent fishing as the water temperature warms and triggers feeding. Catchable-sized rainbow trout are stocked in the lower reservoir as soon as the ice is gone. In the upper reservoir, you'll be fishing for rainbows stocked at fingerling size in previous years. Smallmouth bass remain sluggish until the water temperature reaches 60 degrees in late spring.
