What Indian Island County Park offers anglers
Indian Island County Park sits on the Peconic River in Riverhead, about a mile north of where the river widens into Peconic Bay. The park gives you access to a tidal stretch that holds striped bass, catfish, and seasonal shad — all species that move through this section on predictable patterns. The shoreline is mostly open, with a mix of sandy banks and marsh edge, and the park has a parking area, picnic tables, and a maintained path down to the water.
This is not a destination park if you live hours away, but if you fish the North Fork or central Long Island regularly, it fills a specific gap: a public access point on the Peconic that does not require a boat and does not charge a fee. The river here is narrower and shallower than the bay proper, which means you can read the water and work structure without needing to cover miles of open water.
Key Takeaways
- Indian Island County Park provides free public access to the Peconic River with parking and a maintained path to the water.
- Striped bass move through this section in spring and fall, with the best fishing typically in May and September through October.
- Catfish are present year-round in deeper holes and channels, and respond well to cut bait and chicken liver fished on the bottom at night.
- The park sits in a tidal zone, so timing your visit around the incoming or outgoing tide will determine where fish hold and how they feed.
- Access is walk-in only; there is no boat launch, and the shoreline is shallow enough that wading is possible in most spots during low tide.
Striped bass patterns in the Peconic River
Striped bass use the Peconic River as a migration corridor and as a feeding ground during their seasonal movements. In spring, fish moving into the Sound and toward spawning grounds pass through this section in April and May. They are typically in a feeding mood and will hit small plugs, soft plastics, and live baitfish worked along the deeper channel edges and around any structure — fallen trees, pilings, or the marsh grass line.
Fall is the stronger season. From late August through October, striped bass move back through the river on their way south, and the Peconic becomes crowded with fish. September and early October are peak months. Fish are aggressive, water temperatures are dropping, and baitfish are concentrated. Work the deeper holes and channel bends with topwater plugs at dawn and dusk, or switch to soft plastics and live eels during the day. The incoming tide typically brings more fish into the shallower areas where you can reach them from shore.
Winter fishing is possible but inconsistent. Some years fish linger into November and December in the deeper holes, but most years the population drops off sharply after October. Spring and fall are your reliable windows.
Catfish and bottom fishing year-round
Channel catfish and flathead catfish are present in the Peconic River throughout the year, and Indian Island gives you a solid shore-based platform to fish for them. Both species prefer the deeper holes and channel sections, which run 8 to 12 feet deep in places along this stretch. Cut bait — mackerel, herring, or bunker — is the standard approach, fished on a simple three-way rig or a basic sinker-and-hook setup on the bottom.
Night fishing produces more consistently than day fishing. Catfish feed actively after dark, and the river is quieter and less pressured. Arrive an hour before sunset, set up two or three rods, and fish until midnight or later. Chicken liver, stink baits, and prepared dip baits also work, though fresh cut bait typically outperforms them. The incoming tide concentrates catfish in the deeper holes, so plan your session around the tide schedule.
Summer is the most productive season for catfish, though they bite year-round. Water temperatures in the 70s and 80s trigger more aggressive feeding. Spring and fall can be good as well, but winter fishing requires patience and longer waits between bites.
Shad and seasonal opportunities
American shad move into the Peconic River in spring, typically from late April through May, on their spawning run. They are not as abundant here as they are in larger rivers like the Hudson, but they are present and worth targeting if you are in the area during the window. Small shad darts, spoons, and soft plastics in silver and white work best. Fish the deeper channel sections and work your lure with a steady retrieve or a jigging motion.
Shad fishing is a bonus opportunity rather than a primary reason to visit, but if you are already at Indian Island in May and want to diversify your approach, they are worth a few casts. The same tide and time-of-day logic applies: incoming tide and early morning typically produce better results.
Tides, timing, and water conditions
The Peconic River at Riverhead is tidal, and tide timing directly affects where fish hold and how they feed. On the incoming tide, water pushes upriver and fish move into shallower areas to feed. On the outgoing tide, fish retreat to deeper holes and channels. For striped bass and shad, the incoming tide is usually more productive because fish are actively feeding in the shallower zones you can reach from shore. For catfish, the incoming tide concentrates them in the deeper holes, so fishing the deeper sections during incoming tide is your best bet.
Check the tide schedule before you go. NOAA provides tide predictions for the Peconic River at Riverhead, and most fishing apps include this data. Plan to fish the two hours before and after the tide change, when water movement is most active and fish are feeding.
Water clarity varies with season and recent rainfall. After heavy rain, the river can be murky for a day or two, which actually improves fishing for catfish and striped bass — both species rely more on smell and lateral line detection in stained water. Clear water in summer can make striped bass more cautious, so switch to smaller lures and fish early and late in the day.
Access, parking, and what to bring
Indian Island County Park is located at 1 Riverside Drive, Riverhead, and is open dawn to dusk. Parking is free and usually has space, though it can fill on weekends during peak season. The park has a maintained path from the parking area down to the water, and picnic tables and restrooms are available. There is no boat launch, no bait shop, and no concessions, so bring everything you need.
Wading is possible in most spots during low tide, but the bottom is soft mud and can be slippery. Wear wading boots or sneakers with good grip. The shoreline is mostly open, so you can move along the water's edge and explore different sections. Bring a headlamp if you plan to fish at night, especially for catfish. Insect pressure can be heavy in summer, so bring bug spray.
There is no bait shop nearby, so you will need to bring your own. If you are fishing for striped bass, bring a selection of plugs, soft plastics, and live bait. For catfish, bring cut mackerel or bunker, or prepare your bait at home and bring it in a cooler. A basic tackle box, a few rods, and a net are all you need.
Nearby alternatives and similar water
If Indian Island is crowded or if you want to explore other sections of the Peconic, Grangebel Park in Calverton offers similar access to the river upstream. The Peconic Bay itself, accessible from various boat launches around Riverhead and Southold, holds larger striped bass and more consistent fishing, but requires a boat. For shore-based fishing in the immediate area, Calverton Park and the Peconic River Preserve offer additional walk-in access.
The Peconic River system is relatively small and can get crowded during peak season, especially on weekends. If you fish Indian Island on a Saturday morning and find it packed, consider returning on a weekday or shifting to an early morning or evening session when pressure is lighter.
Frequently Asked Questions
What is the best time of year to fish Indian Island County Park?
Fall, from September through October, is the strongest season for striped bass. Spring (April and May) is also good. Catfish bite year-round, with summer being most productive. Winter fishing is possible but inconsistent.
Do I need a New York fishing license to fish here?
Yes. New York requires a freshwater or saltwater license depending on what species you are targeting. Striped bass require a saltwater license. Catfish require a freshwater license. You can purchase a license online through the New York Department of Environmental Conservation website.
Can I fish at night?
Yes. Night fishing is actually better for catfish. The park is open dawn to dusk officially, but many anglers fish the evening and night hours during the open period. Check current park rules before you go, as policies can change.
Is there a boat launch at Indian Island?
No. Indian Island is walk-in access only. There is no boat launch. If you want to fish the Peconic Bay or explore deeper water, you will need to launch from another location like Grangebel Park or a private marina.
What should I use for bait if I do not have a bait shop nearby?
Bring cut mackerel or bunker for catfish, or prepare it at home and transport it in a cooler. For striped bass, live eels, live shiners, or soft plastics work well. Most anglers bring their own bait rather than relying on local shops, which are limited in this area.
