Parts of the southern shores of Corunna Lake are located within Corunna State Forest. Corunna Lake is a well known speedboat racing area - cruising is also popular given the scenic qualities of its deep and extensive arms. The shallow, saline nature of Nangudga, Tilba Tilba and Little Lakes renders them an important feeding habitat for waterfowl. These coastal lakes, located along a 13 km stretch of coast immediately south of Narooma, have been subjected to extensive infilling from marine sands.
