Pine Creek

The Pine Creek Dam originally became operational in 1970 with a 7,510’ long and 124’ high earth fill embankment.  The outlet works include an intake structure, 13-foot diameter conduit, a 48-inch water supply and water quality bypass, and a 36-inch water supply static head line.  Flow through the conduit is controlled by two 5’ 8” by 13’ hydraulic slide gates operating in tandem.  The dam has been given a Dam Safety Action Class (DSAC) rating of 1 – extremely high risk – as a result of seepage and piping along and into the outlet conduit. Major features of work on the project include a secant pile cutoff wall, chimney filter, downstream invert filter, and 12' diameter steel conduit liner.
