Site description This is by far the largest reservoir of the five impoundments along the upper Tana river, and abuts on the eastern side with Mwea National Reserve (IBA KE032). Masinga dam, which is managed by the Tana and Athi Rivers Development Authority, was completed in 1981. The valley that it drowned has a highly convoluted shoreline and contains a number of sizeable islands. The maximum depth is c.50 m, near the dam wall. Because of periodic draw-down and flooding, the shoreline is bare ground with a mosaic of deposited silt, pebbles and mud. Further from the water, a narrow strip of grass gives way to open Acacia–Commiphora bushland. The area is semi-arid with an annual rainfall of between 250 and 500 mm.
