Isinglass Reservoir near Trumbull: Fishing Spots, Seasons and Access

• Overview

  Isinglass Reservoir falls in Naugatuck Valley Planning Region, part of Connecticut. The land about it is rolling hill. Trumbull at 3.5 miles is the nearest place to stop. Bridgeport is the closest city, 7.5 miles away. Being near a boundary, it pays to know which side you are fishing. Quiet on weekdays, busier when the weather turns fine.

• Where to Fish on Isinglass Reservoir

  Depth is not on record here, which means reading the ground instead. Built water gives depth close in, which suits a bank angler. Points where the flooded channel swings in are the reliable ones. County-wide records name bluegill, white sucker, pumpkinseed, yellow perch and largemouth bass. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. On Isinglass Reservoir that means starting tight and working out.

• Seasonal Patterns

  Between January at about 27°F and July at about 72°F, the water has a wide range to work through. The swings are modest, so patterns change slowly. Hard water here is never dependable, so check for yourself before stepping out. November and March are the quiet, comfortable months to be out. At Isinglass Reservoir the season follows that pattern closely.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. Boehm Pond Open Space runs up to the bank here, which usually means extra restrictions. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Some banks are open only from a marked point. Where the way in crosses private ground, ask first. Failing this one, try Means Brook Reservoir, 2.1 miles away. Confirm before you fish Isinglass Reservoir.
