Central Texas lake dive with park access and modest visibility.
Stillhouse Hallow Lake is a Central Texas freshwater reservoir dive that suits local training and shore practice more than big visibility. Access now centers on USACE parks and designated swim beaches, with the old marina closed and removed, so plan around park ramps, Belton-area dive support, and low-visibility lake conditions. Expect bass, catfish, and other freshwater fish rather than open-water reef life.

Depth range, seasonality, and planning context.
Reported Depth

Depth Note
The reservoir reaches about 107 ft at maximum depth, but many local dives are much shallower and the better-known boat sites can go deeper than 60 ft.
Best Season
Summer and early fall for warmer water; visibility still depends on weather and algae.
Typical Conditions
Freshwater reservoir with modest visibility, gentle shore slopes, and little true current beyond boat wake and wind chop.

Site Conditions
Safety Notes
Visibility can be limited, so consider using good lighting and maintaining close buddy contact.
Access Restrictions
Avoid boat launching sites, designated mooring points, public docks, and other restricted areas. An inland diver-down flag must be displayed during underwater activity.
Legal Notes
Swimming, snorkeling, and scuba diving are allowed at your own risk outside restricted areas under USACE rules.
Community notes to help plan your visit.
Scuba Diving
Good for shore divers who want lake practice, buoyancy work, and straightforward park access rather than big visibility.
Snorkeling
Possible at designated swim beaches, but the low visibility makes it better for short close-range swims than for scenery.
