I have a private man made lake at my house in MN. I do not have a topographical map for it as it is pretty small just about 11 acres. The deepest point that I have found is just over 24′ in the south middle end about 30′ from shore. Recently over the past few days I took advantage of the nice weather and started to drill a grid on the ice to make a topographical map of my own. I have a map of my progress below. My question is I have found a place where the perch bite just as fast as you put the line down at about 8′ just to the north west of the circled 16 on my map, however they are very small 4-5″. Are these considered the bait fish and if so where am I going to find the big fish…..and yes i know for a fact that there are big fish in here as I have caught them over the summer. Are the big fish going to be in a hole or a basin. There are both of those structures the rest of the lake (uncharted area to south). Or will I want to look for the transitions.
There are also trees hanging down in the water along the edge that were very successful in the summer for the bass and sunfish and Northern are those going to be good locations to find them in the winter as well? I would say that those areas will be between the 4-6′ range, or do the fish go deeper in the winter. I know I may be better off to have the rest of my map done first but I wanted to get some pointers as it is fresh in my mind.
Thank you!
