Downtown Pewaukee has a nice pier but it can get crowded on the weekends. Lowell dam and the milpond is another spot that also has a park & picnic area. Do a search for it on the reports page. Couple places in Theresa too on the Rock River. Yet another is take Hwy. 16 West past Oconomowoc and there are several parks along the river. Another millpond and river is in Hustisford I believe, it's near Lake Keesus.
