Why target the night fishing? I don't really understand. There are many smaller lakes in kentucky that are used for water supply. That lake really does not get a lot of traffic anyway because of several things. First is the permit for out of county is pricey. Second is the cost of permit compared to months you can use it(because you cant launch a boat mid summer). Third is there is not enough parking. I can't tell you how many years I bought a permit (out of county) then show up without a spot to park and have to turn around and go home or drive on to somewhere else.
If your willing to spend the money for a permit, fight the parking and willing to launch your boat in a few inches of water then why would they care. Is fishing actually hurting the water supply? If it just trash then they need to target the people who are leaving trash. True fisherman are stewards of the land and water and would not leave their trash.
