RODEO -- The Contra Costa County Flood Control District will come to Rodeo Creek Tuesday to provide an update on the condition of the county's aging flood control channels, detention basins and dams.

Some 79 miles of flood control channels and 29 detention basins and dams have been installed since the district was formed in 1951 and have protected the region from flood damage, according to an agency news release. But many parts of the system are approaching the end of their 75-year life.

Most of the system was built with the help of federal and state funding that cannot be counted on for replacement or upgrade work.

District officials will deliver their update at 1 p.m. near the creek, at the intersection of John and 1st streets in Rodeo.
