Best for intermediate divers, 10-21m, shore & boat entry.
Littlerock Dam Reservoir is a freshwater site in LA County featuring an artificial reef and a wall that descends to depths between 10 and 21 metres. Divers and snorkellers experience visibility of approximately 4 metres. The site is characterised by significant thermoclines, with surface temperatures near 10°C dropping to 3-4°C below 7.6 metres. Due to the cold water and consistently low visibility, this site is suited for intermediate divers who possess strong buoyancy control. Night diving is permitted, allowing for slow exploration of the structures. Facilities on site include parking and toilets. Divers should remain vigilant for boat traffic and use a surface marker buoy during ascent.
