Lake Katherine Fishing Guide, Grafton County, New Hampshire

• Overview

  Lake Katherine belongs to Grafton County, New Hampshire. It sits at 1,345 feet above sea level. It measures about 44 acres, which is a comfortable size for bank fishing. About 1.0 miles of bank, so nothing stays unexplored for long. Supplies mean a trip to Haverhill, 5.5 miles off. After that come Orford at 9.6 miles and Woodsville at 12 miles. The county line runs close by, so rules can change within a short drive.

• Where to Fish on Lake Katherine

  Depth is unknown to us, and the shoreline is the better guide. On a natural lake the weed line and the shelf beyond it do the work. The shallow end warms first and pulls fish in ahead of the rest. Fish documented in Grafton County include rainbow trout, brook trout, smallmouth bass and brown trout. It is the county picture; the agency list is water-specific. On Lake Katherine the quiet end is the one worth the extra effort.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 66°F, while January sits near 16°F. Winter closes the water for a while, and the reopening is worth catching. Expect a solid lid for months and a thaw around mid April. Expect the water usable from around mid April until roughly early December. The first weeks of open water and the last are the ones to plan for. Lake Katherine runs to that rhythm year in and year out.

• Tackle & Baits

  We hold no note on access for this one. It formed naturally, so levels move with rainfall rather than with a gate. A boat ramp sits about half a mile from the water. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Rules differ from one water to the next round here. Some ground is open by custom rather than by right, so tread carefully. Failing this one, try Lake Tarleton, 1 mile away. For Lake Katherine in particular, ask before you travel.
