The Cold Season
Winter in the South Bay
Winter fishing in the South Bay is not for those seeking fast action. Water temperatures drop into the 48–55°F range, metabolism across all species slows dramatically, and fish move less and eat less. But — and this is important — they don't stop eating entirely. An angler who slows down, uses finesse presentations, and targets the right windows of the day will still catch fish when everyone else has given up.
The most important winter rule is to fish the warmest part of the day. Unlike summer when you race to the water at dawn, winter fishing peaks from roughly 11am to 3pm as the sun warms the shallows slightly. Fish that were completely inactive in the cold morning hours become catchable as temperatures climb a few degrees. Midday is your prime window.
Winter's silver lining is rainbow trout. CDFW stocks Almaden Reservoir in December through February, and freshly planted trout are eager biters. PowerBait, salmon eggs, and small spoons produce consistent action. For many South Bay families, this stocked trout fishery is the highlight of the cold months — especially for kids.
Winter Tactics
Slowing Down to Catch More
The #1 winter bass technique. Fish it extremely slowly near the bottom. Hold it in place — the tail quiver does the work.
A finesse worm on a shaky head jig, barely moved along the bottom. Painfully slow — exactly what winter bass need.
Mold a ball onto a treble hook, suspend it 18 inches off the bottom with an egg sinker rig. Best after stocking days at Almaden.
Gold or silver small spoons worked at a slow steady retrieve for planted trout. Also occasionally triggers bass.
Catfish slow down but never stop. Cut bait on the bottom near the dam on mild afternoons still produces.
Skip the cold morning. Arrive late and fish through the warmest afternoon window for the best winter action.
