Instead of waiting for the government to solve the problem years from now, people with property can build or carve out some space on their land for a detention pond. It will hold water and can feed the local aquifers. One problem might be that after so many years of drought, the soils are so compacted or are composed of too much clay, that they won't actually absorb much.

There are a lot of good ideas here, and it's frustrating waiting for "the officials" to research it and then discuss it, go for funding, etc... years go by and still nothing happens.
