During Labor Day weekend expect big crowds at any still waters having easy access. It will be a time to practice courtesy and have patience. Speckled duns are still hatching around mid day to evening at some higher elevation waters such as Aldous Lake and the Sand Creek Reservoir ponds. For Chesterfield and Daniels reservoirs try leech and damselfly nymph patters in deep water. Dry damselfly patterns will be worth trying at Springfield Reservoir. Cooling weather will help bring back action throughout.
