Central Valley & San Joaquin (California)

The Nasdaq Veles California Water Index (NQH2O) tracks the spot price of California water entitlements and publishes weekly on Wednesdays. It closed at $535.91 per acre foot on its August 26, 2026 trade date.

The methodology matters when you use it as a benchmark. It is a volume-weighted average across five markets: Surface Water, Central Basin, Chino Basin, Main Basin, and the Mojave Basin Alto Subarea. It is priced at the source and excludes conveyance costs and losses, so it is not what delivered water costs. The underlying transaction data comes from WestWater Research’s Waterlitix database.

It is also volatile by design. CME notes the 2012 to 2016 drought roughly doubled the index from about $450 to $1,000 per acre foot, and the 2021 drought pushed it above $1,100.

This is the distinction that trips up more California owners than any other, and it belongs in writing in any lease.

Riparian and pre-1914 appropriative rights are the senior tier and need no State Water Board permit. Two cautions come with them: riparian water may only be used on the riparian parcel and covers natural flow only, not stored or imported water; and a pre-1914 right can be lost through five or more consecutive years of non-use. Both still require annual Statements of Water Diversion and Use.

Post-1914 appropriative rights are permitted and licensed by the Board, and changes require Board approval.

CVP and SWP contract water is not a water right at all. It is a contingent annual allocation set by Reclamation or DWR. In 2026 the Central Valley Project south-of-Delta agricultural allocation moved 15 percent in February, to 20 in March, 25 in May, and 28 percent in August. The State Water Project went from 10 percent in December to 45 percent by mid May.

The economics are unusually legible here because a single district publishes both numbers.

A December 2025 UCLA and NRDC study found California cities pay an average of $722 per acre foot for wholesale water while agricultural districts average $36, with Westlands Water District contract water under $40 per acre foot plus a $14 restoration fee.

Westlands’ own March 2026 notice then prices what more water costs once the contract allocation runs out: an operations and maintenance rate of $42.02 per acre foot, estimated groundwater credits at $190, and supplemental water at $550 to $800 per acre foot.

That spread between roughly $40 contract water and $550 to $800 supplemental water is the entire economic basis of the leasing market in the San Joaquin Valley.

The Sustainable Groundwater Management Act requires critically overdrafted basins to reach sustainability by 2040. Where a basin’s plan is found inadequate, the State Water Board can place it on probation, which triggers state extraction reporting and fees.

The Tulare Lake Subbasin has been probationary since April 16, 2024, with fees of $20 per acre foot plus a $300 annual base fee per well. The Tule Subbasin has been probationary since September 17, 2024. Chowchilla, Delta-Mendota, Kaweah and Kern County were returned to state department jurisdiction without probation, Kern escaping on a September 17, 2025 vote.

Stack a $20 per acre foot state fee and a pumping allocation against $550 to $800 supplemental surface water and the substitution becomes rational. PPIC estimates SGMA compliance will require at least 500,000 acres of irrigated farmland, about 10 percent, to come out of production by 2040, rising toward 900,000 acres without new supply or water trading.

Two physical constraints govern nearly every south-bound transfer, and both reduce what a lease can actually deliver.

Transfers can only be conveyed through the State Water Project and Central Valley Project Delta export facilities from July 1 through November 30, under biological opinions protecting Delta smelt and anadromous fish. Moving water outside that window requires consultation with NOAA Fisheries and the Fish and Wildlife Service.

Carriage water is a real volumetric haircut: DWR uses it to mitigate adverse impacts, particularly Delta salinity changes, and it must be priced into any wet-water lease crossing the Delta.

Approvals stack too: the State Water Board approves post-1914 changes, Reclamation must have conveyance capacity, and the Department of Fish and Wildlife reviews fish and wildlife impacts. All three 2026 transfer proposals filed through the state tracking system, totaling 25,642 acre feet, were cropland idling or crop shifting.

First, establish what you actually hold, because a senior pre-1914 right and a CVP contract allocation are different assets with different buyers and very different reliability.

Second, price against the gap rather than the index alone. NQH2O tells you market direction; the district rate sheets tell you what a buyer down the canal is currently paying when their allocation runs short.

Third, watch the calendar. The Delta export window, the October 6 probation hearing, and the October 28 to 29 Bay-Delta Plan adoption vote are all dated events that move what a lease is worth. In a year with full reservoirs and no snowpack, timing is most of the negotiation.
