Volunteers are needed to start replacing the rip rap rock along the east side of the pond at Oasis State Park. Volunteers can work from 8 a.m. to 4 p.m. while park staff is present, according to a news release. The help will expedite the renovation project which has been under way for several months at the park, say park officials. Volunteers need to stop by the park office to complete a volunteer agreement. Information: 356-5331
