Dub Patton Swimming Beach is a freshwater site located within the Dub Patton Recreation Area. It serves as a quiet spot for swimming and snorkeling, with shore access available for visitors. The site is influenced by the silty inflow of the Coldwater River, which results in low visibility ranging from 0 to 3 metres. Due to these conditions, the site is rated for beginners. The habitat supports various temperate freshwater fish and aquatic vegetation typical of the region. Facilities at the recreation area include toilets and showers for public use. Divers and snorkellers should be aware of the low visibility hazard when entering the water.

Old Coldwater Townsite consists of the submerged remains of a former settlement, now located within Arkabutla Lake. The site is a freshwater wreck location featuring structural ruins from the original town. Due to the depth, which reaches up to 17 metres, and the prevalence of low visibility, the site is considered suitable only for advanced divers. Snorkelling is generally not recommended as the ruins are difficult to view from the surface. Access to the site requires a boat. Divers should be aware of potential entanglement hazards associated with the submerged structures.

Engineer's Point Rip-Rap is a freshwater artificial reef located in Grenada Lake. The site consists of large underwater rocks placed along the point, creating a complex topography that extends from 2 to 23 metres in depth. Entry is possible from both the shore and by boat. Divers and snorkellers should anticipate variable visibility ranging from 1 to 6 metres and mild currents. Due to the nature of the site and potential boat traffic, it is best suited for intermediate divers. Facilities available at the location include parking, toilets, showers, changing rooms, a rinse station, air fills, equipment rental, a cafe, first aid, a dive shop, and boat charter services.
