Water is running at 2,330 cfs with a gauge height of 1.55 ft at Point of Rocks — a fishable, slightly elevated late-summer flow with clear visibility in most runs. At 79.3°F the water is warm but cooling nights are beginning to nudge fish into more active feeding windows, especially early morning and evening.

Best Time Window
  • 6 AM - 8:30 AM: Prime low-light window — strip streamers and crayfish jigs through deep channel edges and rocky shelves before the sun hits the water.
  • 10 AM - 2 PM: Terrestrial prime time — work hoppers and ants tight to shaded banks and structure during the warmest part of the day.
  • 6:30 PM - Dusk: Evening caddis and surface activity — fish dry flies in slower tailouts and flats as temperatures drop and fish move shallow.
Guide's Tip
From the benchWith water temps at 79°F, the best bite windows are compressed to the first two hours of daylight and the last 90 minutes before dark — don't waste energy fishing the midday heat with streamers. During the day, switch to a terrestrial presentation: cast hoppers and ants within 18 inches of the bank, let them sit for a full 3-count, then give one subtle twitch before picking up. Target the shaded, downstream face of any boulder or bridge piling where smallmouth are stacking to ambush and stay cool. As the sun drops and temps ease, move to the deeper channel edges with a sculpin or crayfish pattern stripped along the bottom in short, erratic hops.
