The 22.5-acre Post-DIspatch Lake contains 2 islands and more than 14 acres of water surface. It is frequented not only by the many paddle-boaters departing from the Boathouse, but also a large variety of waterbirds and songbirds, including great egrets, bald eagles, American pelicans, purple martins and king fishers. The lake is generally shallow (less than 6 feet), but there are some deeper areas of up to 20 feet for fish habitat. Post-Dispatch Lake is surrounded in many areas with a buffer of native grasses and wildflowers that help filther stormwater runoff and provide great habitat for butterflies, bees and dragonflies. It is so named for an 1894 fundraising campaign by the St. Louis Post-Dispatch — yes, boaters have been enjoying life here for more than a century.
Fishing is not permitted in Post-Dispatch Lake.
