The park is in the easternmost tip of Centre County, south of Clinton County and north of Union County. McCalls Dam State Park is in a remote location on a gravel road between R. B. Winter State Park on Pennsylvania Route 192 and Eastville on Pennsylvania Route 880. The park can only be accessed in the winter months by snowmobiling or cross-country skiing.

A splash dam was a temporary wooden dam used to raise the water level in streams to float logs downstream to sawmills. By impounding water and allowing it to be released on the log drive's schedule, these dams allowed many more logs to be brought to market than the natural flow of the stream allowed. Water releases from multiple splash dams on tributaries were also often combined to maximize the number of logs floated throughout a given watershed.
