This MNR dam is located at the outlet of Tasso Lake, which drains into Tasso Creek and joins the Big East River 4 km downstream at the site of the former Finlayson Pond.

The dam, originally constructed in 1902 and reconstructed several times since, is approximately 4 m high and 4.3 m long. It consists of a single stop-log bay, with eight stop logs, set between two concrete piers, which form the embankment for a road over the top of the dam. The sill elevation is 397.12 m and the crest elevation of the stop logs is 399.56 m The dam is operated on a regular basis since all flow must pass through the single sluiceway (flow over the top of the dam could wash out the road embankment) and upstream flooding is a concern. The target water elevation is 399.4 m. with a drawdown of 0.4 m in March for spring flood control. The purpose of this dam is recreational, but also provides municipal road access over Tasso Creek.
