General Information / History
St. Louis County Parks and Recreation Department purchased the original 148 acres in 1976. In 1977, 33 acres were acquired from the Simpson Company, a sand, gravel and asphalt company. Another acquisition was completed in 1981 with the purchase of a one-acre lot from a private owner. Additional acquisitions of 16 acres have been made through Bond Issue funds and Federal Emergency Management Agency supported purchases of properties along the Meramec River.

The existing lake was created through a combined damming/dredging operation. A dam was constructed to impound water from Grand Glaize Creek. This allowed Simpson Sand and Gravel to float a dredge barge to dredge sand and gravel. This process in turn enlarged the lake. 

The park was dedicated on July 6, 1991.

The Blue Heron Pavilion was completed in June of 1994 with funds from the 1986 Bond Issue and was designed to withstand flooding.

Two L&WCF grants were received in 1992 and 1995 respectively for the construction of the asphalt lake shore trail in the park north of Marshall Road and the Meramec River Greenway Trail that extended the lake shore trail.

In 1996 Taco Bell donated funds for the installation of a soccer field, parking lot and a handicapped accessible fishing dock (lost in the 2017 flooding) located in the main section of the park near the Blue Heron Shelter.
