Natural walleye lakes provide far more walleye habitat than any other type of water.North America natural walleye lakes are home to the majority of the walleye's population, when you look at percentage breakdown of the entire walleye habitat spectrum. Here's a breakdown by percentage: 94% Natural walleye lakes, 5% man-made reservoirs, 1% rivers and streams.
The walleye's habitat range has changed and grown to 32% of all the freshwater of North A merica over the years because of new stocking programs instituted outside their native range creating walleye waters not there before.
You will find very high concentrations of walleye in large shallow walleye fishing lakes, that have medium to to low water clarity. A good example is the western basin of Lake Erie. A large expansion of water is likely to have the windswept shorelines needed and reefs that make ideal walleye spawning habitat. And a shallow walleye fishing lake is likely to provide more food then deep water walleye lakes. A lake needs to have shallow feeding shelves in order to have a good population of walleyes, if the shoreline drops sharply into deep water and these shelves are not present the population of walleye will be much smaller. Another good reason walleyes prefer low clarity walleye waters is because of there very light sensitive eyes.
Lets talk a bit about the different classifications of lakes. The first type of lake we will discuss is a Oligotrophic walleye fishing lake, which have fair to good walleye numbers.Oligotrophic walleye fishing lakes are excellent for spawning because there are so many rocky basins,but they tend to be cold and infertile.
As we said before, a Oligotrophic walleye lake will have fair to good walleye populations, and these walleye fishing lakes are usually cold and infertile, but have many rocky basins that make good spawning habitat. Walleyes in Oligotrophic deep lakes will live longer but will not grow as big or as fast as in shallower, low clarity warmer fertile lakes. Walleyes in these lakes grow more slowly but live longer then in warmer water. Most Oligotropic lakes are in remote areas, so anglers take fewer walleyes.
The largest number walleyes will be found in Mesotrophic walleye fishing lakes. These moderately fertile lakes produce good food crop, so walleyes grow fairly fast. These lakes most likely have natural walleye spawning because there is enough gravel or rubble for a successful spawn. Mesotropical walleye lakes seldom have a winter kill but may lack oxygen at the deeper depths.
