If you fish Lake Ontario or the St. Lawrence River, you have probably watched double-crested cormorants raft up, dive on bait balls, or strip the greenery off an island. Those birds are federally protected, so chasing them off or interfering with nests is not an option. The practical move is to report what you see so biologists and resource managers have real, local data to work with. Here is how Lake Ontario and St. Lawrence River anglers can report cormorant impacts in 2026 using the statewide cormorant reporting survey.

Why Reports Matter to Anglers
Cormorants are native fish eaters, but their numbers in the Great Lakes and St. Lawrence River corridor have drawn serious attention from charter captains, biologists, and shoreline communities. The birds can concentrate around stocked salmon and trout, perch schools, and baitfish, and large nesting colonies can damage island vegetation with guano buildup.
Your eyes on the water are valuable. A single report is just one data point, but dozens of reports from anglers from Sodus Bay to the Thousand Islands can show where birds are feeding, where colonies are expanding, and where they overlap with fishing effort. That information helps managers decide where more research is needed and how to balance bird protection with healthy fisheries.
Fall is an especially good time to report. Post-breeding cormorants gather in big rafts before migration, often over the same structure and bait schools where walleye, bass, musky, and staging salmon are holding. If you notice birds repeatedly working the same area, that is worth logging.
What You Can Report
The statewide survey is built for more than just counting birds. You can document several kinds of impacts, which is what managers actually need.
| Observation Type | Why It Helps |
|---|---|
| Bird numbers and location | Shows concentration areas and seasonal movement |
| Nesting activity | Documents colony size and habitat pressure |
| Feeding behavior | Indicates overlap with game fish and stocked fish |
| Habitat or tree damage | Tracks vegetation loss on islands and shorelines |
| Water quality concerns | Notes algae, odor, or guano-related issues |
| Infrastructure or recreation impacts | Covers docks, boat launches, and fishing access |
Photos make a report much stronger. A picture of a raft, a nesting island, or birds diving on bait gives context that numbers alone cannot. Try to include a landmark, shoreline feature, or GPS coordinates so the location is clear.
How to File a Report Step by Step
The survey is designed to be quick enough to fill out from a boat ramp or your truck, but detailed enough to be useful. Here is the simplest way to do it.
- Open the official New York Sea Grant cormorant reporting page on your phone.
- Allow location access or drop a pin on the map at the exact spot where you observed the birds.
- Pick the category that best matches what you saw: numbers, nesting, feeding, habitat damage, water quality, infrastructure, or recreation impact.
- Enter the date, time, and approximate number of birds. Be honest with your estimate. A hundred birds looks different than a dozen, and either is useful.
- Upload any photos you took. Try to get one wide shot for location and one closer shot for behavior or damage.
- Add a short note about what you were fishing for, water conditions, and anything else that seemed relevant.
- Submit the report. The site includes a real-time viewer, so your observation joins the larger map.
You do not need to be a biologist. If you can describe what you saw, where, and when, the survey can use it.
Tips for a Report That Actually Helps
Not all reports are equally useful. A few extra details can turn a casual sighting into solid data.
- Be specific about location. A GPS coordinate from your fish finder or phone is best. If not, name the nearest bay, island, launch, or channel marker.
- Estimate numbers carefully. Counting a dense raft is tough, but give a range rather than guessing an exact number. “50 to 75 birds” is more credible than “about a million.”
- Note behavior. Diving repeatedly, herding bait, sitting on nests, or flying to a roost all tell different stories.
- Record water and weather. Water temperature, wind direction, and time of day help managers understand seasonal patterns.
- Include fishing context. If you were marking fish or catching a certain species nearby, mention it. That shows overlap between cormorant activity and angling.
- Do not harass the birds. Cormorants, their nests, and their eggs are protected under federal law. Keep your distance and let the camera do the work.
What Happens After You Report
Your report does not trigger an immediate response at the spot. Instead, it gets added to a statewide dataset that New York Sea Grant and partner agencies use to track trends, identify hotspots, and guide research. Because cormorants are protected by the Migratory Bird Treaty Act, any management action has to go through federal and state review. That takes time, and it takes good data.
The real-time viewer also lets you see what other anglers and shoreline residents are reporting. If you notice a pattern building on your favorite bay, that is a signal to keep logging observations and to talk with local biologists at public meetings.
Keep Fishing Through the Flocks
Bird activity can tell you that bait is present, but it is not a reason to crowd a flock, approach a nesting area, or interfere with feeding birds. Keep a respectful distance, make your observation for the survey, and move to nearby structure where bass, walleye, or musky may be using the same general forage base.
Once you are clear of the birds, use your electronics to check nearby points, breaks, and bait schools. An inline spinner is a useful search tool when you need to cover water. For bass or walleye, the Livingston Lures EBS Spinner 50 offers a compact profile. For musky or northern pike, the Blue Fox Musky Twin Turbo provides a larger presentation. Over deeper bait, a compact blade like the Tail Spin in Fire can be jigged vertically or cast to schooling fish.
Summary
Lake Ontario and St. Lawrence River anglers can report cormorant impacts in 2026 by submitting observations, photos, and location details through the official statewide reporting page. Fall is prime time to document rafts, feeding activity, and habitat effects while you are already on the water. The more anglers who report, the better the information managers have for understanding both the birds and the fisheries we care about.
