Big Twin Lake, California: Fishing Spots and Seasons

• Overview

  Big Twin Lake stands in San Luis Obispo County, California. Elevation runs to 36 feet. It covers about 20 acres, so this is small water you can walk round in under an hour. It lies lower than most water we list in California. The closest town, Callender, is 1.4 miles away. Further out sit Oceano (2 miles) and Arroyo Grande (3.5 miles). You are close to a county edge here; who manages the access can change within a short drive.

• Where to Fish on Big Twin Lake

  Without a survey to go on, judge depth from how the bank falls away. The tide is the timetable on this water; two hours either side of the change usually fish hardest. The productive water is a rod length or two out, not a hundred. Weed, then depth: that is the order to fish a water of this kind. County-wide records name jack mackerel, flathead grey mullet, yellowtail amberjack and rainbow trout. The county list is broader than any single water. Big Twin Lake responds to conditions more than to tactics.

• Seasonal Patterns

  The warmest month averages 62°F, the coldest about 52°F. Summer heat is the limit here, not winter cold. Heat pushes fish deep from June onwards, so start early. Late winter often fishes better here than midsummer does. It sets the rhythm of the year at Big Twin Lake. Long dry spells drop the level and concentrate them.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. A campsite lies 0.9 miles away for anyone staying over. Mapping records toilets within half a mile. Light line and small metal for the trout; a fly rod earns its place on calm evenings. State or provincial rules still apply whatever the bank status. Close seasons apply to some species and not others. The nearest alternative is Hospital Lake, 0.2 miles out. Treat Big Twin Lake as unsettled until someone local tells you otherwise.
