On June 12, 1948 the available storage in Lake Mathews reached the highest point since completion of the ~ reservoir at 101.314 acre feet.

P-ipe l-ines and reservoirs The upper feeder consisting of precast concrete pipe, steel pipe, tunnels. and cast-in-place concrete canyon crossings extends 60.8 miles from Lake Mathews to the Eagle Rock control tower on the westerly buumlary of the City of Pasadena. The capacity of the upper feeder is 750 cubic feet per second to the San Dimas turnuut and 510 cubic feet per second from that puint to Eagle Rock Near La Verne in Los Angeles County the flow of the upper feeder is diverted at a turnout structure into the water softening and filtration plant. softened and filtered. and returned to the upper feeder for distribution to District areas. The City of Pasadena is supplied directly from the Pasadena tunnel of the upper feeder through a riser pipe at Mountain Street and Manzanita A venue_ This riser is connected to a large city main which delivers water to near-by Sunset reservoir. A second Pasadena outlet is provided near the easterly cit~' boundary at Sierra Madre Villa A venue. There are at present three main branches extending from the upper feeder southerly and westerly into the metropolitan area. with laterals as required to carry water to the member cities. The Orang" County branch takes oW from th" upper feeder at the softening plant turnout structure and runs in a southerly direction 40_3 miles to connect with the existing Laguna Beach main supply line near Corona Del Mar. Direct cOlinections are made from the Orange County line to the city systems of Brea, a constituent of Coastal Municipal Water District, Fullerton. Anaheim. and Santa Ana at points designated by these cities. Two reservoirs on this line. the Orange County and Corona Del Mar, provide storage and flow regulation_ The Palos Verdes branch runs southerly and westerly from the Eagl" Rock tower 31.0 miles to the Palos Verdes reservoir near the Los Angeies Harbor-Long Beach area. Ten connections. including a short lateral to Ascot reservoir. have thus far been made from this line to the Los Angeles city water system. and laterals were
