Merry Lake Fishing in Grant County, Washington

• Overview

  Merry Lake lies in Grant County, in Washington. The setting is open dry country. At 9 acres it is the sort of place you fish for an evening rather than a day. The town to know is Mattawa, 7.8 miles out. The nearest city of size is Tri-Cities, 52 miles away. You are close to a county edge here; who manages the access can change within a short drive.

• Where to Fish on Merry Lake

  Open data we checked carries no depth for this water. Rip-rap along the wall holds fish that the open bank never does. Draw-down through summer strips the margins, so follow the water out. Survey and observation records for Grant County include yellow perch, largemouth bass and bluegill. County data is a starting point rather than a guarantee. On Merry Lake that means starting tight and working out.

• Seasonal Patterns

  Long-term averages put July at about 74°F and January near 30°F. The year turns gently, without extremes at either end. Cover comes and goes, so treat it with suspicion rather than trust. November and March are the quiet, comfortable months to be out. That is the shape of the year on Merry Lake.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. The car has to stay 0.9 miles away, which shapes how much tackle you bring. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Where access is informal, keep it that way by behaving. Where tickets apply, they are sold in the nearest town rather than on the bank. For a change of water, Lenice Lake is 1 mile distant. None of that is settled for Merry Lake in what we hold.
