A rockfill dam on the Oued Chelif 155 km from Algiers, 105 m of maximum embankment height, 270 m crest, 15 m crest width, a 70 m spillway with twenty reinforced concrete labyrinth fusegates and two 15 m metal flap gates, and a 100 m3/s bottom outlet; built from 1927 and impounded in 1939 with an initial capacity of 280 hm3; the 2004 bathymetric survey gives 115.26 hm3, implying mean siltation of 2.24 hm3 a year over 1939 to 2004 against a design assumption of 3.2 hm3 a year; the same document states 96.72 hm3 elsewhere, a contradiction flagged in the notes; mean inflow 2004 to 2012 was 47.88 hm3 a year against a design assumption of 148.5 hm3.
