Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2016-0272-R5, pursuant to Section 1602 of the Fish and Game Code to Los Angeles County Flood Control District. To minimize clogging and/or other impacts to dam operations prior to each storm season, sediment will be removed from an area approximately 140 by 170 upstream of the dam, approximately 0.54 acres. Sediment removed from this area shall be temporarily placed within a 2.75 acre temporary sediment placement known as Johnson's field that is owned by City of Pasadena. This site is located on the northeastern side of the reservoir, approximately 1,000 feet from the sediment removal area. The existing access roads will be used to gain access to the sediment removal area, and transport sediment to Johnson's field before soil, organics, and trash removed from the face of the dam will hauled to Scholl Canyon landfill. The existing access road may need to be re-established from the existing paved road used for hiking and maintenance access to provide access to reservoir's invert area along the face of the dam.
