River Systems

146 of the lakes, meres, tarns & waters flow into the sea through a total of 13 river outflows. The remaining 20 either have no surface outflow or the outflow leads to a marsh rather than a river system. The 13 river systems are shown below, identified by the river that flows into the sea, in a clockwise order from the south-east. Click on the lake names to view the lakes and their details.
