I’ve got a few sweet spots of heaven that I get into a few times a year. How much you want to learn is all up to how much time your going to invest, or how much effort your willing to invest.
Here are some random things I have done:
Internet – search, search more, and keep searching. I’m speaking more to WI, because this is where I have devoted most of my efforts. Lake Property Assoc. have formed and been dissolved, Grant money gets awarded, Proposals for purchase by the state that fell through, fyke net studies, and the list goes on and on. A lot of times I have stumbled onto information about one lake while searching for another. Invasive species studies are another source of finding information that may not exist on creel or fyke net studies, but can contain valuable info.
Open water – We have access onto one lake that is privately owned property all the way around. Problem is, no boat landing and its taken almost 19 years to have a property owner allow me to back down their yard to launch my bassboat. Previously, it was a carry-in jon boat. I still rigged up my H/Bird 1197 and used it as a mapping tool. By leaving the tracking line on and using the trolling motor to run around all day, I was able to make a bap of major contour lines. Also, my favorite little lake has NO WEEDS. So by zig-zagging all over, I found found transition lines and granite boulders. A lake that many would think is a 90 acre dead sea, actually has an abundance of mud flat transitions to natural rock piles, crevices, and other structure that 90% of people would over look.
Another thing to apply to “Blind Searching” is understanding how different species relate to that specific type of habitat. I’ve found a lot of spring fed lakes with no weeds hold huge gills – but in very low numbers. Where most people think of gills relating to weeds or tight cover, these fish will suspend for most of their life. What I call Pot Hole fishing is finding quality gills in 20 to 30 fow and usually suspended. BUT, they could also be feeding the larvae emerging from the mud flats or transition lines.
I’ve also come to understand how much more predator fish constantly roam much larger areas. For me, it seems as if the smaller the lake, the more they travel or less schooling and more scattered hunting approach.
Use common sense. I say that more for once someone unlocks the secrets of these little lakes. Many of these little lakes that honestly sees little to no pressure have a very delicate eco system in place. If a lake is 90 acres, it may only have 30 acres of suitable habitat for walleyes. With a mature population density of 8 (on the high side) your looking at a total population of about 240 mature walleyes in that lake. Wouldn’t take long to over harvest and throw that lake out of balance.
There is a lake in northern WI that I have almost 25 years of fishing on that is well under 100 acres. I came across this lake from a study I found on half logs and a grant to enhance the bass and walleye population to combat an abundance of perch. About 18 years of that has been incredible. Walleyes up to 29″, bass over 6#, and 11″ gills. A couple property owners got into fishing and heavy harvesting of anything that eats a leech and can go into a frying pan. Perfectly legal that they catch/eat within the bag limits. But now we are seeing the down side of it. Tiny perch again, lack of predators, and less and less young of the year fish. Won’t be long until its back to how it was – Way over fished. Sorry for getting a bit long on this. These little gems in the middle of nowhere are a real special place for me.
