Merlo Lake in Sonoma County: How and When to Fish It

• Overview

  Within Sonoma County, California, you have Merlo Lake. Open plain runs right down to the water. With some 44 acres of water, there is room for a boat but no need of one. The bank runs about 1.0 miles all the way round, so one visit can cover most of it. It lies lower than most water we list in California. Nearest place of any size is Cloverdale, 7.8 miles away. Healdsburg is 8.9 miles and Guerneville 13 miles. No border sits close enough to matter.

• Where to Fish on Merlo Lake

  There is no recorded depth, so work from what you can see. Weed, then depth: that is the order to fish a water of this kind. Read the surface for the wind lane, then fish the edge of it. Open biodiversity records for Sonoma County list flathead grey mullet, rainbow trout, Chinook salmon, bluegill and cabezon. Protected fish appear in the records for this area, so treat the list as information, not an invitation. Anyone new to Merlo Lake should walk it once before setting up.

• Seasonal Patterns

  Climate normals give 71°F for August and 47°F for January. Winter here means light layers, not lost months. The cooler months are the comfortable ones to be out. June to September is hot work, so the first and last hours are what count. Anyone fishing Merlo Lake regularly works to that calendar.

• Tackle & Baits

  No access rule appears in what we hold. This is a natural basin, not a dammed one. There is no recorded infrastructure here; expect to find your own way in. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. A phone call first saves an afternoon. Keep proof of licence with you rather than in the car. Lake Sonoma at 4.4 miles is the sensible second choice. For Merlo Lake, the notice at the access point is the final word.
