Triangle Lake in Sussex County: How and When to Fish It

• Overview

  Triangle Lake is one of the Sussex County waters in New Jersey. The coast is 29 miles away. You can fish the entire water from one spot if you pick it well. It is a small entry by Sussex County standards. Start from Ogdensburg, 5.2 miles down the road. Then Franklin, 5.3 miles, and Hamburg, 6.6 miles. Local rules may differ a few miles either side of here.

• Where to Fish on Triangle Lake

  No published figure covers depth, so learn it as you fish. This is a lake, so the margins and the first drop matter most. The shallow end warms first and pulls fish in ahead of the rest. Sussex County records list brook trout, brown trout and walleye among the fish reported. County records show what lives in the area; the local agency holds the water-by-water list. At Triangle Lake the first feature you find is worth twenty minutes.

• Seasonal Patterns

  Long-term averages put July at about 70°F and January near 25°F. A lid forms in a hard winter only. Some winters give nothing at all, so plan for open water. March through May is the strongest run, with October and November a second stretch. That is the shape of the year on Triangle Lake.

• Tackle & Baits

  Whether you may fish here is not something records settle. There is no mapped parking or launch nearby, which keeps numbers down. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Gates get locked out of season on water like this. Night access is frequently treated as a separate matter. If the gate is shut, Oak Ridge Reservoir at 1.9 miles is the nearest alternative. Check the position at Triangle Lake before loading the car.
