20 feet depth of ALL waters in Cowhead Lake (Cal. Civil Code Secs 1410-1422). Same scheme as Hartnett/Ayres claims: dam 12 ft high on North end, tunnel through hill to ravine system, thence to lands N and E of Alkali Lake. Tunnel 7x5 ft, ditch 8x4 ft, capacity 2852 miner's inches.
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.
