A Department of Natural Resources Boat Passes By

 This was another thing that passed while I was taking pictures of the Tregurtha.

When I see a boat that looks like, I expect to see some sort of law enforcement vehicle.

Usually it is a US Coast Guard vessel.  Sometimes it is a Border Patrol vessel.  Occasionally, it is the Ontario Police.  A few times it has been the Mounted Police.

This time it was a Conservation Officer.  With the number of fishermen on the river, this doesn't come as a surprise.

And yes, they can arrest you if you are doing something wrong.
