Clear Lake

Where it is

Clear Lake sits in Lake County, California, about a two-hour drive north of San Francisco. The lake is the largest natural freshwater lake fully within California, with three distinct basins (Upper Arm, Lower Arm, and the Oaks Arm) connecting through a narrows. Estimates of its age vary, but it is generally considered among the oldest lakes in North America — around 480,000 years.

Seasonal pattern

Spring (March–May). The biggest trophy window. Pre-spawn fish stage along tule edges and shallow flats as water temps climb through 55°F. Spawn rolls through April. Senkos, swim jigs, lipless cranks, and big swimbaits along tule lines and rocky points produce.

Summer (June–September). Surface temps push into the upper 70s. Bass cycle through tules at first light, slide to outside grass and rock points mid-day, return shallow at last light. Frogs over mat algae, dropshots on rock points, and topwater on schooling fish.

Fall (October–November). Cooling water concentrates baitfish and pulls bass shallow again. Cranks, jerkbaits, and swimbaits along tule edges and rock.

Winter (December–February). Mild West Coast winters keep the bite open year-round. Slow-rolled jigs, jerkbaits, and dropshot in deeper water.

Don't take "Clear" literally

The name comes from the lake's original character, not a current condition — the modern lake is often murky from algae blooms (especially blue-green cyanobacteria in late summer), runoff, and wind-stirred sediment. Clarity changes dramatically across the three arms, with the Oaks Arm typically clearer and the Upper Arm often the muddiest. Plan a day's bait selection around the arm you're fishing.

Key structure

• Tules (round-leaf bulrush) — extensive shoreline cover, year-round
• Submerged rock piles and shoals — Konocti Bay, Sulphur Bank, and the islands
• Submerged docks and pilings — particularly in Lakeport and Konocti coves
• Drop-offs from shallow tule flats to deeper open water

Forage

Hitch (a native California minnow) is a defining forage species — both a target and a distinctive cue for what bass are eating. Threadfin shad and inland silversides are the open-water baitfish. Bluegill and crayfish round out the system.

Access

Multiple public ramps in Lakeport (Library Park, North Lakeport), Clearlake (Redbud Park), Kelseyville, Nice, and Lucerne. Konocti Vista Casino and several private resorts have ramps; fees vary. Most ramps are paved with courtesy docks.

Regulations

Standard California bass regulations apply with seasonal nuances. Always verify current rules with the California Department of Fish and Wildlife before fishing — California's rules vary by water body and shift more often than most states.
