The mingling of salt and fresh water at the mouth of the Connecticut River in Old Saybrook and Old Lyme attracts striped bass and bluefish that chase baitfish here all summer. For shore-anglers, one of the most productive spots is a thousand-foot-long fishing pier right at the DEP Marine Headquarters at Ferry Landing State Park. Across the river, just below the I-95 bridge, is the Baldwin Bridge State Boat Launch and Fishing Pier. Farther downstream, near the mouth of the river, the state has another fishing pier on the Route 154 Causeway that crosses the mouth of South Cove. Boat anglers can also launch at the Great Island State Boat Launch on the east side of the river or at the town boat launch in Old Saybrook, at North Cove on the west. Top baits for stripers or blues are bunker and silversides. Five-inch Bomber plugs, one-ounce Fjord spoons and big leadhead jigs are productive lures.
