A still, cloudless night on the water, with a persistent wind from the W and pressure going nowhere. Give sheltered bays and points the first hour at Gropp Lake. Expect the better fishing from night into morning. Give the likely spots time before moving. Fish follow the bait in autumn, so find one to find the other.

Night
The Mercer County end of New Jersey holds Gropp Lake. Land around it is mixed woodland. At about 31 acres, a day is enough to walk the shoreline properly. Supplies mean a trip to White Horse, 0.9 miles off. It is 27 miles to Edison, the nearest city. Nearby alternatives: Spring Lake about 2.5 miles, Sturgeon Pond lies 3.3 miles on, Colliers Pond about 4.9 miles, Colonial Lake lies 5 miles on and Crystal Lake about 5.3 miles. A border sits close enough to be relevant to the paperwork.
Nothing in our records gives a depth for this one. Standing timber shows when the level drops, and fish sit against it. Points where the flooded channel swings in are the reliable ones. Open biodiversity records for Mercer County list bluegill, largemouth bass, pumpkinseed and white perch. Those are county-wide records, so not every one of them will be in this water. At Gropp Lake the water rewards a slow, careful approach.
Long-run averages give July about 76°F and January about 31°F. Seasons here are moderate, and the fishing runs most of the year. In milder years the edges alone go, and the middle never sets. Late winter often fishes better here than midsummer does. Time your trip to Gropp Lake by conditions rather than dates.
Nothing in our records says who may fish here. The car has to stay half a mile away, which shapes how much tackle you bring. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Look for a notice board at the entrance. Fishing rules and camping rules are set separately here. If the gate is shut, Spring Lake at 2.5 miles is the nearest alternative. What applies at Gropp Lake may have changed since it was mapped.
