75% confidence 80°F Clear 2.1 mph
If trout are stocked, they will be less active in 80°F surface water—target deeper areas or early morning if you want to test them.
comprehensive plan Analyze Weather Conditions Analyze Past Water Temperature Analyze Species Behavior
Largemouth bass and bluegill are the most likely active species right now.
Why:
- The lake-page modeled surface temperature is 80°F (updated today). That's within the prime activity range for both species and above the comfort zone for trout.
- Calm, clear conditions (wind 2.1 mph, pressure 30.00 inHg) favor a finesse, quiet presentation—exactly what you'd use for bass holding near cover or bluegill in shaded shallows.
- August is peak warmwater season; no recent catch data is available, but the temperature and weather pattern align with active bass and panfish, not coldwater species.
What to verify on site: The official species list for Spring Valley Reservoir was not included in the current evidence. Check Idaho Department of Fish and Game stocking records or the lake sign to confirm which species are present.
