On Wednesday, March 23, I checked surface and ice conditions at Lake Cascade, Horsethief Reservoir, and Payette Lake. Unfortunately, recent warm temperatures have significantly reduced ice thickness around the edges of Cascade and Payette Lakes - making them both unsafe for ice fishing. On Lake Cascade, I visited each public access area from Blue Heron to Poison Creek and observed only a very thin layer of ice along the shoreline. On Payette Lake, I visited the Mile High Marina boat ramp area and observed similar conditions. With continuing warm weather in the forecast, it looks like ice fishing season is wrapping up in Valley County. However, Horsethief Reservoir is still accessible. I measured 8 inches of ice below 8.5 inches of white ice (compact slush) with little to no snow on the surface. This measurement was taken roughly 30 feet out from the King's Point boat ramp.
Ice conditions and thickness can vary greatly in a given area. Drill holes and check for yourself - use caution and don't go alone. Ice can be very thin along cracks as ice sheets expand and contract, as well as near any current from rivers or creeks entering the lake. Be careful out there and watch out for each other!
Printed maps of ice fishing access areas on Horsethief Reservoir are available at local tackle shops in Cascade and McCall, as well as the Fish and Game offices in McCall and Nampa. For fishing regulations, recommended species, and other information for the McCall area, visit the Idaho Department of Fish and Game Fishing Planner, or contact the McCall Fish and Game office at (208) 634-8137. Good luck and stay safe out there!
