I put the statement about dams and groundwater to our conservation guys... here is one of the responses.

Groundwater storage does require facilities to divert the water and temporarily store it over permeable ground so that seeps into the aquifer. Generally, these facilities are smaller and less damaging to the environment than large surface storage dams and reservoirs. You can also use passive designs. The flood bypass system in the Sacramento Vally takes flood overflow from the Sacramento and Feather Rivers. Some of that water flows into the Delta but quite a bit seeps into the ground. The San Joaquin has no such flood bypass system and a significant groundwater overdraft problem. The Sacramento Valley have few if any groundwater overdraft problems. Interesting, no?


That's from Steve, our Conservation Director.
