Only electric motors are permitted on the lakes. Much of the shoreline is also accessible to bank fishing. The lake's backwaters contain heavy vegetation during the summer and this produces excellent surface plugging action. Even though its waters are much shallower than the other lakes we discussed, Lake Assunpink still has plenty of open water and 10-foot-plus water where plastic baits will provide you with good bass-fishing action. In particular, the old streambed that is still visible on a depthfinder produces some excellent numbers of bass on jig-and-pig and jig-and-plastic worm combinations.
Assunpink Lake, at 225 acres the largest of the wildlife area lakes, was created around 1970 by damming Assunpink Creek. Anglers are lured by an abundance of lakes in Monmouth County, some stocked, some not. Of the 26 fishing lakes in the county, only three are run by the state Department of Environmental Protection Division of Fish and Wildlife. They are the three lakes in the Assunpink Wildlife Management Area: Assunpink Lake, Stone Tavern Lake and Rising Sun Lake. The lakes are the products of the joint efforts of the U.S. Soil Conservation Service and the New Jersey Division of Fish and Wildlife as well as the New Jersey Green Acres Program. They were built around 1970 to provide flood protection for the Assunpink Creek, drainage, fish and wildlife habitats, and recreation. Each lake provides fishing opportunities and small boat access. "It’s a very popular area for fishermen," Raymond J. Porutski, regional superintendent of the Division of Fish and Wildlife’s Central Region Office, said of the Assunpink Wildlife Management Area. "The main lake [Assunpink Lake] has a large class bass, so is a really good largemouth bass fishery for trophies," he added. The fisheries management program is directed toward largemouth bass as the major game species, so largemouth bass are abundant, as are channel catfish. These species were first stocked in the early 1970s. Hybrid striped bass are also stocked, and hybrids in excess of 5 pounds are not uncommon. Angling opportunities for chain pickerel and black crappie are excellent, Porutski said. Both bluegill and pumpkinseed sunfish are present, with the bluegill being the more numerous. Brown bullhead are also present. Chain pickerel are present, especially in Assunpink Lake, where they reach up to 18 to 20 inches. The Assunpink, the largest of the three lakes, encompasses 225 acres. A new boat ramp is being constructed at Assunpink Lake. Instead of a dirt strip down to the water, it will be concrete with a little dock, and there will be expanded parking. Parking and launching facilities for both car-top and trailered boats are available at the access site off the Clarksburg-Robbinsville Road.
