Monday the 4th of July I was entering Lake of the Isles and noticed a police boat behind me. I pulled off to the side before entering Lake of the Isles. It was an OPP boat. After they passed I followed them into Lake of the Isles. They entered the first bay in US waters and weaved through the boats that were rafting there. A few people were taking pictures and it looked like one on shore was shooting video. It looked like all the boats were from NY. The OPP proceeded through Lake of the Isles and into the Rift. When I went through the Rift and came out by Wellesly Island State Park they were gone. I haven't figured out what they were doing yet. Possibly looking for Canadian boaters to warn them? Has anyone heard anything about this? I'm heading back to the 1000 Islands and I'm going to check in and then fish in Canada to see what happens.
