Do you see a lot of fish using the structure?
Added structure, weed lines and weed flats that are linked (by position)will all have fish relating to them during the summer. They use the linked structure as travel paths from one area to another, for feeding as well as safe areas from large predators.
In the winter when the submergent weeds are mostly gone, they relate to isolated structure wherever it is.
Speaking of large predators... When Gail and I were fishing later in the day I caught one of those famous Bremer Pond wide back NP. It was 15 plus pounds of fury that was weighed and with a mighty thrust wrenched itself out of my hand and back into the depths. They do make your heart level increase no matter how many times you catch one!
