Loch Tarsan

Loch Tarsan is a freshwater loch and impounding reservoir located 13 kilometres northwest of Dunoon, Argyll and Bute, Scotland. This three-armed Reservoir extends into both Glen Tarsan and Glen Lean. It supplies water to the Striven Hydro-Electric Scheme. The larger of the two dams is 17.6 metres high and was completed in 1953. The water that is collected in the loch is piped to the hydro-electric generating station, located at Ardtaraig, at the head of Loch Striven.
Angling on the loch is managed by Dunoon and District Angling Club.
The B836 road passes the loch.
