California Codes, Civil Code - CIV, Division 2 — Property, Part 4 — Acquisition of Property, Title 8 — Water Rights, Section 1420
Persons who have heretofore claimed the right to water, and who have not constructed works in which to divert it, and who have not diverted nor applied it to some useful purpose, must, after this Title takes effect, and within twenty days thereafter, proceed as in this Title provided, or their right ceases.
Notes
Requires persons who previously claimed water rights but neither constructed diversion works nor diverted and beneficially used the water to proceed under the title within 20 days after it takes effect. Failure to act within that 20-day period causes the claimed water right to cease.
