Friends of Prompton State Park, a grassroots organization is working to take over management of the park in much the same way that Salt Springs State Park in Susquehanna County is managed by The Friends of Salt Springs Park.Northeast Sports Ltd. of Honesdale sponsors several outdoor sports events that are held at the park.
