Just like one of the many polar plunges we have in this area, building a stone reef begins with removing the ice from a section of a lake. After that, the two events differ.
The organization Walleyes for Tomorrow was out on Pike Lake, just south of Hatley on Saturday, cutting holes in the ice and filling the holes with rocks.
They're building a spawning reef in the hopes of increasing the natural reproduction of walleyes in the lake.
"It basically gives it a raised surface off the top of the lake bottom that the walleyes will come up and spawn in, and it gives the eggs, and when they hatch, the fry, a place to hide from predators," says Dan Weith, president of the Central WI Chapter of Walleyes for Tomorrow.
This is the first event for the Central Wisconsin chapter, and Weith says it couldn't have gone smoother.
Their next project is going to be a portable walleye hatchery to serve many of the lakes and rivers here in Central Wisconsin.
