Pursuant to your request, I have researched an issue raised in the course of my review of responses to the Division of Water Rights’ 2015 Information Order submitted by water right claimants within the Legal Delta.

I. Question Presented

Under California water law and within the Legal Delta, are there any circumstances under which riparian and appropriative rights can “overlap” becoming indistinguishable or inseparable such that either or both may be lawfully exercised at the election of the holder?

II. Short Answer

It is possible to perfect both riparian and appropriative water rights for beneficial use on the same parcel. However, riparian and appropriative rights are distinct property interests that must be separately established. There is no California precedent recognizing “overlapping” or “intertwined” water rights, and water laws against hoarding and non-use operate to preclude the duplicative exercise of water rights.
