Ashton Reservoir draw-down begins tomorrow and will take two weeks to complete. Expect discolored water during this event and for a while afterwards. However, discolor should not be as bad as last September when unconsolidated sediments up to 100 years old moved out. Impact on wet fly fishing is less likely than to dry fly fishing during draw-down. A streamer pattern of the evening presented in areas out of direct sunlight remains the best way to encounter a large fish until stonefly nymphs begin moving.
