Modesto Irrigation Dist. v. Tanaka
Annotate this CaseAppellant Heather Robinson Tanaka’s great-grandfather purchased a subdivided parcel that had been part of a larger riparian tract but was no longer contiguous to water. Riparian rights can persist in land sold under such circumstances, though the grantee cannot acquire riparian rights any greater than those held by the grantor. The question presented for the Court of Appeal's review was whether the parties intended the grantee to receive riparian rights in such a transfer. "The clearest expression of intent is when a deed expressly conveys the riparian rights to the noncontiguous parcel, in which case the parcel retains its riparian status. However, where the deed is ambiguous, extrinsic evidence is admissible on the question." Here, the trial court, after considering the language of the deed at issue and extrinsic evidence, concluded the conveyance to Tanaka’s great-grandfather did not convey riparian rights. As a consequence, Tanaka had no rights to divert water from Middle River onto her small, approximately 106-acre parcel that has been used for farmland for 130 years. The Court of Appeal disagreed with the trial court’s conclusion and reversed.
