We used to have underwater lights off our dock. They have to be replaced every few years and it isn't cheap. When they went out again last year we decided not to have them replaced. A big factor on this decision was not having them be an attractant for people to drive onto our yard. A lesser influence was kayakers. Many times we'd be out on our deck leaning on the rail watching the reds and trout sillouetted in our lights, when a kayaker, who saw us out there but didn't care, paddled right up and cast into them, spooking them. It was often common for groups of kayakers to be out their at all hours making noise while they fished while we were trying to sleep. Of course kayakers have the right to use the canals and usually we had no problem with them fishing over our lights when we weren't out there enjoying them, but there are rights, and then there is common courtesy. Our lights would still be out there for people in kayaks to enjoy fishing from if people on land and sea had shown some common courtesy.
Don't drive into other peoples' neighborhoods to fish from the canals. The land surrounding the canals is private property and you're trespassing. Especially don't drive onto peoples' lawns.
If you enter a neighborhood by boat, you're fine, as long as you stay in the canal. Fishing over lights is usually fine, however, please give preference to the people who paid for the lights and are paying for the electricity. If people from the house adjacent to the lights you're fishing walk onto their dock with fishing gear, kindly pack up and move on to another spot. It's also best if there are people out on their deck over their boathouse, to find another spot. And be conscious of your noise level, especially between 10 PM and 8 AM. Thank you.
