Hansen Spreading Grounds

The 156 acre spreading grounds were developed in the early 1940s to accept water from the lower Tujunga (below Hansen Dam) to provide a place for surface water to recharge ground water and aquifers. The capacity of the spreading grounds at any one time is 279 acre-feet and the percolation rate is 150 cfs (facility information from LA Department of Public Works).

In the winter and spring of 2004-05, the Hansen spreading grounds allowed 29,180 acre-feet of water to percolate into the ground-water (LADPW water conservation report).
