River Diversion / Island / Air Intake Tunnel

During construction of the home, workers diverted the waterway a half-mile from its original course so it flowed through the back yard and created an island behind the home. Later, a tunnel ran from the banks of the creek into the mansion's basement and provided cool air throughout the home on hot summer days. , Can you see the brick pump-house on the island that provided water to the sprinkler system and other areas of the estate? Take the boardwalk trail and you will see some of the stones the family deposited in the river to create the sound of a babbling brook in their backyard. , .Look for the opening to the tunnel that leads to the house. , .As you walk the boardwalk trail, look for the remnants of a bridge that once crossed to the island. , .You may also glimpse some private homes on the other side of the Ottawa River.
