The creeks and marshes in the lowlands of Pewaukee converge near the Simmons Woods Wetlands. From here the water flows into the Pewaukee River, which in turn empties into the Fox River to the south. We recently took a hike in Simmons Woods Park and took the above shot. The trees are barely leafing out, but it is still a place of pristine, natural beauty. This view looks east towards a heron rookery (see image below) where the Great Blue Herons make their nests in tall bare trees within the safety of the marsh.
