I have fished the driftless area for over half a century. 55 years to be exact. Some things I find take me back to the olden days and other things like garbage and discarded vehicle make me cringe and ask to myself what were people were thinking when they threw away things in river and stream beds.
This water control tower is all that is left of a failed Corp of Engineers project of Lake Lafarge.
