Lake Murvaul offers multiple public boat ramps in Panola County, with Decker-Hill Park being a primary access point featuring three concrete ramps, a public fishing pier, courtesy docks, and full amenities including restrooms, picnic areas, and camping facilities.

The ramp is located at the north end of the dam off FM 1234 and operates 24 hours year-round with no boat launch fees, though camping fees apply.

Tinkle Park on the south shore provides an alternative two-lane concrete ramp with similar amenities, also maintained by the Panola County Fresh Water District.
