Great views of Petenwell from along the dike is what you will find here. The Dike is straight as an arrow, with a wide gravel walking path at the top. I try to avoid rock hides whenever possible, but all there is here is rocks, so not many options of where to hide a cache here. So to make it easier, the cache is just north of the wooden post, and I placed a small cairn next to the cache to make it easier. If you want to make the cairn taller, please do so.
The Wisconsin River is the hardest working river in the nation. From its headwaters on the Wisconsin-Michigan border in Lac Vieux Desert, it falls more than 1,000 feet on its 500-mile journey through the state, before emptying into the Mississippi River at Prairie du Chien.
Since the Ice Age, the mighty river has scoured gorges and cut great rapids and waterfalls, whose roar has been replaced by the hum of turbines and waterwheels at 26 hydroelectric dams. The energy generated each year would supply the electrical needs of every home in Madison for a year.
The Wisconsin, long notorious for devastating floods, is now partially controlled by 21 reservoirs (flowages) on the river. Many reservoirs are lowered prior to spring runoff in anticipation of high water when spring breakup begins.
The Petenwell Dam and the Castle Rock Dam (its sister downriver) are unique, because they are built on sand and were the first such projects undertaken in the United States. The concrete dams are classified as "floating-type construction" with imbedded cutoff walls that penetrate deep into the glacial sands, permanently anchoring them.
