The District operates and maintains flood control facilities that have been constructed by the District, or by others and transferred to the District. Routine maintenance is conducted on all District facilities to ensure proper operations. Maintenance typically involves removal of sediment and vegetation to increase conveyance capacity of flood control channels. Also, the District maintains 40 dams or debris basins to remove sediment from channels that have the potential to cause downstream flooding of residential or commercial areas. Storm related maintenance is conducted on an as-needed basis, usually during emergency conditions, to protect life and property. The Division Manager for Operations & Maintenance is Karl Novak.
