Other nearby places to fish
The shoreline is heavily indented — bays, points and spits. Look for largemouth bass at the mouths of the bays and on the drop-offs behind the points. The islands add structure: drop-offs around their perimeter and channels between them and the bank.
The wind builds its wave along the north-west — south-east axis — 16 mi of open water; along north-east — south-west there is only 4 mi. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.
Reservoir Lower Granite Lake (Washington) — one of the area's fishing spots. About 16.8 km² in area. The town of Clarkston is nearby. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.

Lower Granite Lake — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably. Peak 07:00–09:00 and 18:00–20:00.
The computed water temperature is around 57 °F — colder than the 57–75 °F comfort range for Black crappie: the fish conserves energy and takes more cautiously.
Black crappie works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is rising 0.06 inHg over the day — the bite usually settles down after a rise.
One more input — the moon's feeding windows: within their hours the score sits higher than across the rest of the day. The window times are in the “Solunar feeding periods” card below.
October is an active season for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +59°
The day is 3 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldG1 geomagnetic storm, Kp 4.7
Kp index — NOAA data. Not part of the bite score: catches show no link between geomagnetic storms and the bite.
The windows are set by the moon's transit and rise, and the forecast above already accounts for them: within these hours the bite score sits higher than across the rest of the day, while the day's overall level still comes from the catch-calibrated model.
