27-acre lake near Jefferson Township. The lake tops out around 24 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Every species below gets its seasonal read from the same numbers driving the chart.
Shoreline on the chart totals 2 miles. The 2.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 91% of the surface — that's where the groceries are. Figure 0.7 mi of water from one end to the other, 0.2 mi at the beam. Morris County claims this one. Clinton Reservoir sits 6 mi northeast — the closest neighbouring chart.
