I think this has certainly become more relevant in recent years as we've seen significantly elevated flows on within the last decade on the Calaveras below New Hogan. Notably, the Old Calaveras River channel has much more shallow banks than the flood conveyance pathway of Mormon Slough, but can be regulated by the Headworks at Bellota.

Again, restoring riparian habitats (e.g., floodplains) can not only help mitigate some flooding, but also create important habitat, aid in groundwater recharge, and help with fire management. But, probably not enough by itself to account for precipitation whiplash.

Flood informed Reservoir Operations will help to minimize the negative impacts of ARs while also working to improve stormwater capture

Flooding during wet winters and springs, particularly warm rain on a heavy snowpack during wet years. The reservoirs were designed to primarily store snowmelt. With climate change there will be more rain and less snow, resulting in more runoff.

Surface Water connection and storm water with groundwater data for interaction. May not be sufficient.
