Historical Flood Information for Lakeport
Floods can occur with little warning, as they did in January and March 1995, and in January 1997. Stream levels can increase over ten feet within hours of the storm's onset.
Due to its size, Clear Lake responds more slowly to storm events and rises to flood stage only after prolonged storms, as occurred in 1998. When this happens, Clear Lake's natural outlet, Cache Creek, is too small to allow floodwater to leave the lake as fast as it enters. Contrary to popular belief, the Clear Lake Dam does not cause Clear Lake to flood. The dam can actually release water much faster than Cache Creek can flow. It is the narrow, shallow Cache Creek channel that slows the release of water from Clear Lake during a flood.
As we are able, we will post information about past flooding information and photos of floods that impacted our city.
