How this score is calculated

Water temperature18.3 / 20

66°F and falling (-2.1°F / 3 days) against a 58–82°F active band.

Barometric pressure15.0 / 15

29.93 inHg and falling (-0.06 / 24 h).

Wind10.0 / 10

9 mph out of the W. Ideal chop on wind-blown structure.

Water clarity10.0 / 10

2.9 ft of visibility. Good working clarity for both reaction and finesse baits.

Water level9.4 / 10

-1.6 ft from normal pool and rising (+0.6 ft / 7 days).

Moon & solunar5.2 / 10

56% illumination. Quarter moon — weaker feeding periods, rely on light change.

Seasonal pattern9.8 / 10

Fall pattern is fully established.

Sky & rain12.0 / 15

77% cloud, 66°F air, 0.3 in of rain in 24 h.

WhyWater has dropped 2.1°F in three days, so fish are sliding back to the first deeper break, falling pressure ahead of a change usually triggers a feeding window, heavy cloud extends the low-light bite well past sunrise, a 9 mph W wind is stacking bait on the wind-blown banks.

Backup pattern

Slow trolling small jigs at 0.6 mph for crappie — Docks and brush; the spring bite in the sloughs is excellent.

Lake structure and depth zones

Today: 4–13 ft — Largemouth Bass0 ft15 ft30 ft45 ft60 ftShoreline / bankShallow flatDrop-offOffshore humpLedgeMain channelSecondary point
Typical structure profile for Clear Lake: tule shorelines, boat docks and pilings, submerged grass and cabomba beds, rocky points around konocti. Average depth 27 ft, maximum 60 ft.
  • Tule shorelines
  • Boat docks and pilings
  • Submerged grass and cabomba beds
  • Rocky points around Konocti
  • Rip-rap on the Lakeport and Clearlake shores

Substrate

Bottom composition and why it matters

  • Mud 26%

    Warms fastest in late winter and holds wintering bait, but goes dead in the summer heat.

  • Vegetation 22%

    Oxygen, shade and ambush cover. The outside grass edge is the highest-percentage line on most lakes.

  • Sand 14%

    Clean bottom for bait schools and sight-feeding fish, but little cover — look for the edge where sand meets something else.

  • Rock 12%

    Holds heat in spring and crayfish year-round — the first place smallmouth and staging bass set up.

  • Gravel 12%

    Primary spawning substrate. Fish stack on gravel transitions when water hits the 58–66°F band.

  • Clay 10%

    Holds hard bottom in stained water and dumps the most colour after rain. Crankbait banks.

  • Timber 2%

    Vertical cover fish use to change depth without leaving structure — key on standing timber during frontal swings.

  • Brush / artificial 2%

    Man-made brush piles and docks concentrate crappie and bass, especially where they sit on a depth change.

Best time
First 3 hours after sunrise and the last 2 before dark

Stages from wintering creek channels to secondary points at 52–58°F, spawns on hard bottom at 62–68°F, then slides to grass edges and ledges once surface water passes 78°F.

Crappie

Docks and brush; the spring bite in the sloughs is excellent.

Lure
1/16 oz hair or plastic jig (1.5"–2")
Color
Chartreuse / black-blue in stained water

Best time
Late afternoon and full dark under lights

Moves to shallow wood at 56–62°F to spawn, then relates to 12–20 ft brush all summer, and follows shad into creek arms in fall.

Catfish

Big channel cats in the sloughs and on the flats at night.

Active temp
60–85°F
Structure
River channels, holes below points, flats adjacent to deep water
Technique
Anchored cut bait / drifting flats
Bait
Cut shad, skipjack, chicken liver
Lure
Circle hook 6/0–8/0 on a Santee rig (Palm-size bait chunks)
Color
n/a — scent driven
Retrieve
Static or 0.5–0.8 mph controlled drift
Best time
Sunset to midnight; all day when water is stained

Pushes shallow to spawn in rock and bank holes at 70–78°F, then feeds on channel edges at night through summer and gorges on shad in the fall.

Bluegill & Panfish

Beds along the tules from May onward.

Active temp
60–82°F
Structure
Beds on hard bottom, dock shade, inside weed lines
Technique
Small jig under a float
Bait
Red worms, crickets
Lure
1/32 oz jig (1")
Color
Black-chartreuse
Retrieve
Dead-stick with tiny twitches
Best time
Mid-morning to mid-afternoon

Beds through several moon cycles from 68°F on, then holds the inside weed edge.

Patterns

Season-by-season patterns

Winter

48–52°F

Slow-roll a jig on the rocky points and fish the deeper dock pilings; a jerkbait works on clear, calm days.

Spring

58–70°F

The famous window. Big females on the tule edges and shallow flats — crawfish-colored crankbaits, swim jigs and flipping baits.

Summer

74–80°F

Topwater over grass at dawn, then dock shade and deeper weed edges through the day.

Fall

58–72°F

Shad schools in open water; a swimbait and a spinnerbait on wind-blown points.

About Clear Lake

Clear Lake is a natural, nutrient-rich lake with tule-lined shorelines, docks, submerged grass and huge populations of threadfin shad, hitch and crawfish. Its fertility produces exceptional average bass size, and multiple 30 lb five-fish tournament limits have come from here.

Local knowledge

Expert notes

  • Wind is the friend here. A 10–15 mph chop on the tule edge puts big fish right against the stalks; slick calm pushes them out to the grass line.
  • Clear Lake bass eat crawfish heavily in spring. When water is 55–62°F, a red or brown squarebill on rip-rap outfishes shad patterns dramatically.
