  • Diablo Lake To Be Drawn Down Three Feet in Early Oct., Trailer-Launched Boats Affected

    Diablo Lake will be drawn down 3 vertical feet for facility repairs from October 1-15. During the drawdown, boats with trailers will not be able to launch or take boats off the water. Hand-launched vessels will still be able to launch. More »

  • Cascade River Road will be open as normal through fall/winter 2014

    Cascade River Rd. will be open in 2014 until snow conditions make it impassable to vehicles, as normal. The road closure that was planned to begin September 8 has been postponed beyond 2014 due to unforeseen circumstances. More »
