You can view the state regulation HERE:
The reasonable use of metal detectors is permitted in many state parks. However, metal detecting is not permitted where this activity would conflict with a facility in use, nor is it permitted within fenced areas of swimming pool complexes.
Metal detecting on beaches and in lake swimming areas will be permitted within a reasonable distance of shore from the Tuesday after Labor Day until the Saturday prior to Memorial Day, unless posted otherwise. During the summer season, metal detecting in beach and swimming areas will be at the discretion of the park manager based on the manager's knowledge of the use and type of facility.
Metal detecting in other underwater areas will be permitted within a reasonable distance of shore if it does not conflict with other activities or have potential for causing damage to the facility.
Many state park areas have the potential for the recovery of valuable historical objects. State park areas with this potential may have part or all of their area closed to metal detecting.
