Rosedale Park encompasses 472 acres that includes a 38 acre lake stocked with trout. The land on which the park stands was originally three farms. The dam for the lake was built by the Soil Conservation Service starting in 1969. The lake was filled in 1971 and stocked for fishing. Around the lake are two picnic areas with a dozen picnic tables, two playgrounds, areas for playing volley ball and baseball and grassy fields for recreation. The trails wander through the woods and old farm fields to the Hunt House (one of the original three farms). This is an excellent area for flying kites, bird watching, fishing and general recreation.
