Mastens Lake Fishing in Sullivan County, New York

• Overview

  Mastens Lake lies in Sullivan County, in New York. The setting is rolling bush. Roughly 106 acres: a morning covers one end, an afternoon the other. The whole outline is near 1.4 miles, and most of it is walkable. Size puts it in the front rank of our Sullivan County list. Supplies mean a trip to Rock Hill, 3.2 miles off. Wurtsboro lies 3.5 miles off, Monticello another 8.4 miles. A county line runs close by, so local bylaws can differ within a short drive.

• Where to Fish on Mastens Lake

  The records we hold are silent on depth, so plan to find it yourself. A soft bed grows weed late into autumn, which keeps fish shallow. This is a lake, so the margins and the first drop matter most. Fish documented in Sullivan County include brown trout, brook trout, smallmouth bass, white sucker and rainbow trout. County records show the wider picture rather than this one place. Fish Mastens Lake where the bottom changes rather than where it looks deep.

• Seasonal Patterns

  On the long-term average, July reads 68°F and January reads 22°F. Fishing here follows the temperature more than the calendar. Expect a solid lid for months and a thaw around early April. Break-up sits around early April on average, with the water closing again about mid December. The middle of summer slows a little, with dawn and dusk carrying it. On Mastens Lake the same rules apply, with local timing.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. This is a natural basin, not a dammed one. Nothing is listed nearby for parking or launching a boat. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Parking is often the real limit rather than the bank itself. Night access is frequently treated as a separate matter. Wanaksink Lake at 1.6 miles is the sensible second choice. What applies at Mastens Lake may have changed since it was mapped.
