Reached a deal? File the Transfer Request Form

Every Lease, Permanent Transfer or Transfer of Carryover needs the Watermaster's approval before it takes effect. The Seller (Transferor) or Lessor files one Transfer Request Form, completed and signed by both parties.

Check with the Watermaster that this is still the latest revision.

Have these ready

  • Each party's WMID, or check “Requesting new WMID”
  • Assessor Parcel Numbers (APNs) within each WMID
  • Point of Extraction: Private Well(s) with SWNs identified, or the Mutual Water Company
  • Type of Allocation: Base Agricultural, Supplemental Agricultural, Commercial or WWD (Water Works District)
  • Lease: Amount of Allocation Basis Leased (AFY), Term of Lease, Date Lease Commences and Date Lease Ends
  • Permanent Transfer: each party's Allocation Basis BEFORE Transfer, the Allocation Basis to be Sold (AFY) and copies of both Water Rights Grant Deeds. If sold with a conveyance of a parcel, the APNs and a copy of the deed.
  • Transfer of Carryover: Amount of Carryover to be Sold (AF)
  • Maps of where the water was used by the Transferor and where the Transferee will use it, with production facilities marked
  • Initials and signatures from both parties

Good to know

  • Only Agricultural and Commercial allocations can be transferred, and only for use inside the Basin. (Judgment § 4.12.1–4.12.2)
  • Both parties must be in Good Standing. Unpaid assessments are paid before the Transfer takes effect. (§ 4.12.3)
  • Allow up to 120 days for a decision. Transfers to your own adjacent parcels in the same Management Area, or from a Mutual Exclusive Shareholder to its Mutual Water Company, are decided within 45 days. (§ 4.12.4.2)
  • Leases run for whole Water Years only. The Lessor stays responsible for Basin Assessments and Overuse Penalty Assessments unless the lease says otherwise. (§ 1.61, § 4.12.6.1)
  • A Transfer of Carryover adds the carryover to the Transferee's Annual Allocation and removes it from the Transferor's. (§ 4.12.6.3)
  • The parties choose whether the Transfer takes effect at the start of the Water Year it's approved in, or the next Water Year. (§ 4.12.6.4)
  • The Watermaster may charge fees to process requests. (§ 4.12.7)

This board only connects Sellers, Buyers, Lessors and Lessees. It is not a broker, takes no part in negotiations, and does not confirm that a poster holds the allocation or carryover they list. Every Transfer must follow the Las Posas Valley Basin Adjudication Judgment and requires Watermaster approval.
