Lake Tyers is a relatively natural estuary containing three drowned valleys. The flooded valleys form the lake and join together to enter the sea at the western end of the long Corringle - Ewings Marsh - Pettman Beach. Tertiary rocks rising to 20 - 40 m high hills and bluffs, form the southern side of the inlet and provide the location for the small town of Lake Tyers. The persistent southerly waves usually build the beach across the entrance, blocking the lake from the sea. The Lake Tyers road terminates at the inlet where there is a boat ramp, large caravan park and a car park for Shelly Beach. The beach is also accessible at the western end from the bluff-top car park at Red Bluff. The beach extends from the usually closed lake mouth 2 km south-west to the 40 m high sandstone and shale bluffs at Red Bluff. This small bluff is the only bedrock outcrop on Ninety Mile Beach between Cape Conran and Wilsons Promontory. The bluff is surrounded by a rock platform, with reefs in the surf zone. The beach is fully exposed to the southerly waves which average 1.5 m. They produce a straight beach, with a moderately steep beach face, usually fronted by a 2-3 m deep, 50 m wide longshore trough, seaward of which the longshore bar is cut by deep rip channels every 250 m. read more
