Best action at southeastern Idaho reservoirs is at Daniels Reservoir, but larger fish are being caught at Chesterfield Reservoir. Both have low water levels, but cooler weather keeps water temps at good levels for fish activity. Try midge pupa under indicators and look for depth where fish are taking. Small leech and damselfly nymph patterns presented on full sink lines will work deep. Springfield Reservoir is slow fishing, but sure to pick up as newly released fish adjust and water cools. Water levels in Twenty-Four Mile reservoir are very low. Water needs to be impounded for fishing to improve. Fishing at Sand Creek Ponds is picking up thanks to cooler weather. Try midge pupa patterns under an indicator or small leech patterns.
