Cal. Water Code § 1440 — Temporary Urgency Changes

A temporary change order issued under this article shall not result in the creation of a vested right, even of a temporary nature, but shall be subject at all times to modification or revocation in the discretion of the board. The authorization to divert and use water under a temporary change order shall automatically expire 180 days after the authorization takes effect, unless an earlier date is specified or the temporary change order is revoked. The 180-day period does not include any time required for monitoring, reporting, or mitigation before or after the authorization to divert or use water under the temporary change order. If the temporary change order authorizes diversion to storage, the 180-day period is a limitation on the authorization to divert and not a limitation on the authorization for beneficial use of water diverted to storage.
