Fishing Mercer Bog in Somerset County, Maine

• Overview

  Somerset County in Maine is where Mercer Bog sits. It lies 279 feet above sea level. The water covers some 124 acres, so pick a bank rather than trying to cover it all. The shoreline runs about 3.2 miles, so it pays to pick a stretch and stay with it. New Sharon sits 4.5 miles from here and is the nearest stop. Then Rome, 5.9 miles, and Norridgewock, 7.7 miles. A county line runs close by, so local bylaws can differ within a short drive.

• Where to Fish on Mercer Bog

  Nothing in our records gives a depth for this one. Look for where the old bank line still shows under the surface. Held water runs deepest at the wall and shallows back to the inflow. Records held for Somerset County cover Atlantic salmon, brown trout and smallmouth bass. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Work Mercer Bog in sections rather than trying to cover it.

• Seasonal Patterns

  The warmest month averages 67°F, the coldest about 16°F. Winter puts a hard lid on this one. Once it clears, about mid April, the fishing comes on quickly. Break-up near mid April, freeze-up near early December: that is the shape of an average year. The first weeks of open water and the last are the ones to plan for. Time your trip to Mercer Bog by conditions rather than dates.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Mercer Bog Wildlife Management Area covers this ground, which means extra rules to check. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. A phone call first saves an afternoon. Where tickets apply, they are sold in the nearest town rather than on the bank. North Pond, 4.8 miles away, makes the obvious fallback. Treat access at Mercer Bog as something to verify.
