Olanche Creek Diversion Project

Olanche Creek Diversion Project

LADWP proposes to divert a portion of the flow from Olancha Creek into the Los Angeles Aqueduct for municipal use in accordance with pre-1914 appropriations and a 1925 Court Decree. The remaining, non-diverted portion of Olancha Creek flow would continue east of the LAA to irrigate existing vegetation. A weir, wingwall, control gate, and pipe would be installed where Olancha Creek meets LAA at the Overhead 73 structure. The proposed project involves the excavation of a settling basin (50 ft long by 50 ft wide and approx 2 ft deep) that would extend west from the westerly edge of the LAA to allow for sediments to settle out of the creek flow before it enters the LAA.
