Lake Zurich provides many dive sites along the left and right shores. Usually the visibility in the water is worse than that of Lake Lucerne, but there are more fish (in general). The upper part of the lake (between Rapperswil and Schmerikon) is usually unclear because the river Linth provides many particles. Probably the sink to the ground before the water passes the dam between Rapperswil and Pfäffikon. There are also no dive sites listed in the Swiss Dive Guide.
