Granite Lake in Napa County: How and When to Fish It

• Overview

  Granite Lake belongs to Napa County, California. The bank gives way to oak and grass. Small even by pond standards, it rewards one careful line. On size it sits at the modest end of our Napa County list. Supplies mean a trip to Angwin, 1.7 miles off. Santa Rosa sits 17 miles out, and it is the nearest city worth the name. No county line comes close, which keeps the paperwork simple.

• Where to Fish on Granite Lake

  Nothing in our records gives a depth for this one. Weed, then depth: that is the order to fish a water of this kind. On a natural lake the weed line and the shelf beyond it do the work. Public occurrence data for Napa County names Chinook salmon, rainbow trout, Sacramento sucker and bluegill. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. Granite Lake fishes better once you know its edges.

• Seasonal Patterns

  Expect July near 72°F and December near 45°F on the long-run figures. The hard part of the year is the heat, not the cold. The cooler months are the comfortable ones to be out. April and May are the settled weeks, with October close behind. On Granite Lake the same rules apply, with local timing.

• Tackle & Baits

  No access rule appears in what we hold. We find no slipway, car park or made path within a short radius, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Ask in the nearest town if you are unsure. Rules for boats are stricter than rules for the bank in many places. Failing this one, try Lake Newton, 0.1 miles away. Check the current arrangement for Granite Lake.
