Today’s Clear Lake Bass Probability Score

Know the best arm before you launch.

South lake: Rattlesnake arm rock piles, Keys deep docks, steep rocky banks, Cache Creek, and shad balls — especially when rain muddies the north bowl.

Bite windows

Timing is built from sunrise/sunset, wind, cloud cover, heat, and moon phase.

75Morning window6:10 AM–9:30 AM

Start shallow around tules, outside grass edges, shade lanes, and clearer pockets before boat traffic and sun pressure build.

65Midday adjustment11:00 AM–3:00 PM

Move to dock shade, deeper tule edges, rock/dock transitions, and outside weed edges. Slow down if wind dies.

69Evening pushLast 2 hrs before 8:24 PM

Look for windblown points, shade lines, and bait activity. Reaction baits improve if wind holds.

Patterns & lures

Recommended baits update from wind, heat, cloud cover, water temperature context, and algae/HAB risk.

Skipped Senko / Ned / shaky head

Heat and sun push fish toward dock shade, shade pockets, and slower presentations.

Craw jig / Texas rig

Water temperature is in a workable bass-feeding band for rock, tule edges, and transitions.

Finesse away from stagnant bloom pockets

HAB caution favors cleaner water, wind-mixed banks, shade, and deeper edges over stagnant shallow mats.

Zone scores

Each arm is scored separately before the best arm is selected and colored on the probability map.

43Upper Arm

Conditional / lower confidence

North bowl targeting from JD Blackmore: Lakeport docks, Nice/Lucerne docks and trees, Rodman Slough, tules/brush, and creek mouths can play when the water is not blown out. After rain, downgrade muddy runoff and hunt clearer pockets.

65Oaks Arm

Playable secondary pattern

Mid-lake/Oaks targeting from JD Blackmore: the transition near Soda Bay and Buckingham starts the steeper, rockier water with more depth under docks. Prioritize clear water, dock shade, rock/dock transitions, and shad moving past deeper docks.

68Highlands Arm

Best current public-data read

South/Highlands targeting from JD Blackmore: Rattlesnake arm rock piles, the Keys, deep docks, steep rocky banks, Cache Creek, and shad balls are priority targets, especially in winter or after rain when clearer water may hold south/mid-lake.

Why this score?

The model explains the major boosts, caps, and confidence penalties instead of hiding the logic.

  • Wind is outside the ideal range, so the model leans more selective.
  • USGS lake level / Rumsey-style gauge is connected and factored into accessibility and shallow-cover confidence.
  • Latest public HAB record says Caution, so stagnant shallow-water confidence is capped.
  • Water temperature feed is stale, so seasonal phase is used as context rather than a hard live reading.
  • Moon phase is included for bite-window timing, but it is a smaller factor than wind, water, and algae risk.
  • Highlands Arm is currently ranked highest after comparing heat, wind, algae/DO risk, and seasonal zone patterns.
