Physical Features

The Bega River enters the ocean through Mogareka Inlet, a short, narrow and significantly shoaled entrance channel downstream of Hancock Bridge, the bridge being less than 0.5 km from the entrance. The tidal limit is located close to the junction of Jellat Jellat Creek and the main river, approximately 11 km upstream of the entrance (or half way to Bega). Unlike most other coastal rivers on the South Coast, the Bega River delivers fluvial sand all the way to the ocean during periods of flood. The river is navigable to the tidal limit. Water depths of up to 15 m are observed alongside steep shoreline areas downstream of the tidal limit. The river entrance is located at the northern end of Tathra Bay approximately 3 km north of the town of Tathra.
