About Lake Washington

A Storm Warning System was installed on Connor's Point on November 1, 2005. Funding for the system was provided by the Lake Washington Improvement Association, and the Connors Point Cooperative Association provided the property for the location of the system.

The system will be tested on the first Wednesday of every month. If a severe storm or tornado is spotted by trained observers, LeSueur County will activate the Lake Washington warning system. We hope that the new system will provide a more safe environment for Lake Washington home owners and fishermen on the lake.

Lake Washington Home Sites

The homes on Lake Washington have changed significantly over the years. In the early days, most of the homes were seasonal cabins. There were year around homes on the lake in the 1950's and most of them were on Linder Bay Lane or Washington Boulevard. Today there are approximately 450 residences and most of them are year around homes.

Several new developments are being built or planned adjacent to Lake Washington. Those developments are: Baker's Acres, Eastwood Court, Island View Heights, the Biehn properties on Biehn Drive. Lake Washington is where many people from the Mankato and St. Peter area spend time during the summer and winter even if they do not own a home site on the lake.
