Divers wishing to dive Rock Lake must make arrangements through a recognized dive shop. Dive shops may contact Ladyhawk Agua Negra Ranch at 505-472-4102 or info@ladyhawkaguanegraranch.com.

In addition to signing a release, providing a copy of their advanced certification card and paying an entry fee, divers must bring their own equipment, air, food and water.

Tanks and air fills (no Nitrox) are available at Santa Rosa Dive Center at the Blue Hole.

Rock Lake is diveable year-round. In warm months, 7 mm wetsuit with hood or drysuit is comfortable. In colder months, a drysuit is preferred.

Admission to Rock Lake also includes nearby Swan Lake, a quarter of a mile north of Rock. Swan is shallower, warmer and was used for instruction in the early 90s. Entry to Swan Lake is limited. At Rock Lake, divers utilize a concrete dock and metal ladder for entries and exits. At Swan Lake, however, there is no dock and divers must negotiate slippery rocks for shore entries and exits.

All diving is done at the diver’s own risk. Ladyhawk Agua Negra Ranch, Red hawk Diving, or Deborah Ladyhawk does not provide site supervision or telephone service. Divers are strongly urged to bring cell phones and first aid supplies.

Remember, Ladyhawk Agua Negra Ranch is a working ranch. Respect the land and lock all gates.

Diving at Rock Lake can be a unique and rewarding experience for competent, trained, responsible divers.
