Aare river mouth
Fig. 3: The mouth of the Aare channel in Lake Brienz. One can clearly see that the river is transporting a lot of sediments. Lake Brienz acts like a cleansing basin for Lake Thun, whose water is much more clean and better suited for diving. Nikon D200; Δt=1/320 s; f=100 mm; f/9.0; ISO 400; 14 May 2008 13:20:01
