This water right does not appear in California's eWRIMS database. The holder likely has not filed
a Statement of Diversion and Use with the State Water Resources Control Board. Pre-1914 rights are
only in eWRIMS if holders voluntarily filed — many have not, making these rights less visible to the state.
