Every article I read says the same thing, and they touch on the real permanent fix. The only option anyone gives is a insufficient band-aid. How are these lakes fed?? Ground Water / the Water Table, and runoff to a lesser extent. What was Crystal Lake before the Sauk dam? A mud puddle and a few cattails at best. My friends grandparents live down near the ferry (on the Lodi Side) and have lost 200 yds of lawn in the last 40-50 years - that is from where their shore is now out to where it used to be. The Wisconsin Lake levels have been rising, and the dam is holding back more water now than ever to keep the big boat guys and sprawling development happy. And the rain last summer almost breached it. Heck, 10 years ago you could put a 4winns boat under the Okee bridge, now the DNR & Sheriff can't even get under it. From my days in Limnology at UW-Madison, water is one of the most powerful forces on earth. The water has no where to go but around the dam (aka Ground Water) and it does this quickly (in ground water terms) due to mainly sand soil. Go out to a nearby field and dig down a few feet - it is all sand!
This is no means a quick fix, but a few inch lowering of Lake Wisconsin (which is millions gallons larger than Crystal Lake and Fish Lake) could result in considerably greater lowering of Crystal Lake levels. With some major pumping to get the excess water out now and lowering Wisc. Lake level down is the long-term fix. Now the trouble is to get the DNR to hear it and go thru all the bureaucracy crap that is our great DNR, State, ad special interest groups.
