The wet Winter that California has experienced in 2024 is putting some of the dams in the news because they are spilling water. That provides better visuals than I can find on the USACE websites.
We see water flowing in the outlet works. The concrete apron to the right of the outlet is the spillway. [USACE_project]

| @ 1:24 The USACE is spending 100s of millions of dollars to improve the dam. This includes increasing the height of the dam & levees and a larger outlet works. |
In addition to flood control, the reservoir helps replenish the groundwater, and it provides a wildlife refuge.
I used Google Earth to see what the reservoir looks like in a dryer year. It is a good thing that the purpose of the reservoir is flood control and not water supply because it gets rather empty.
