About Cache Creek Dam in Lake County
Woodland City Councilman Bill Marble was at Cache Creek Dam last week and took a photograph of water moving at 20,000 cfs. "A flood event at 60,000 cfs will be something to concern us all," he said.
From the Lake County website:
Due to its size, Clear Lake responds slowly to storm events and rises to flood stage only after prolonged, high intensity storms. 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 Cache Creek Dam does not cause Clear Lake to flood. The dam can 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. The limited flow in Cache Creek causes Clear Lake to rise rapidly during heavy, prolonged rainstorms and does not lower lake levels very fast after the rains have stopped.

That is why we need to remove the silt build up in the settling basin, clear it from Cache Creek, raise and reinforce the walls of Cache Creek and need up stream storage to take the surge of water if they need to release water from Clear Lake or Shasta.
That is also why Woodland cannot allow the weir to be raised to "protect Sacramento / Natomas" as it will increase water pressure on Cache Creek levees before water can overflow into the settling basin.
This is why Sacramento and Woodland should develop only in areas out of the floodplain.

Nice phote. The Cache Creek dam is not used for flood control only for irrigation.
