Water Supply Update (March 2025)

Byron, CA (March 18, 2025) – The Byron-Bethany Irrigation District (“BBID” or “District”) has a positive update for its customers regarding California’s current water supply conditions. As of mid-March, California’s snowpack and reservoir conditions are in relatively good shape:

  • Statewide snowpack: 89% of the April 1 average; 92% of normal to date
  • Northern Sierra snowpack: 99% of April 1 Average; 102% of normal to date
  • Central Sierra snowpack: 80% of April 1 Average; 84% of normal to date
  • Southern Sierra snowpack: 81% of April 1 Average; 84% of normal to date

Major reservoirs across the state are at or above historical levels. San Luis Reservoir, a critical storage facility for both state and federal water projects, is at 87% of capacity and 103% of historical average. Other major Northern California reservoirs are ranging from 111-123% of average.

The Bureau of Reclamation announced its initial Central Valley Project 2025 allocation on February 21, 2025, at 35% for South-of-Delta agricultural contractors, including BBID, and 75% for municipal and industrial users. Further increases are possible due to additional precipitation, improving snowpack, and overall positive hydrological conditions.

Given these favorable conditions and the current allocation levels, BBID does not anticipate any curtailments for the 2025 water year.

“The current water outlook reflects a significant improvement from recent drought years,” said BBID General Manager Ed Pattison. “This positions us well for 2025, allowing our agricultural and municipal customers to move forward with greater certainty.”

The District remains committed to securing all available water supplies and defending its water rights to serve our community, and will provide updates to ensure customers remain well-informed throughout the season.

BBID Water Supply Update – August 2022

Byron, CA (August 25, 2022) – The Byron-Bethany Irrigation District (“BBID” or “District”) has an important update for its customers: as of this posting, the District’s water rights are not curtailed, meaning water deliveries will continue as normal.

Back in July, the State Board approved and adopted a revised Emergency Regulation regarding water use and curtailment in the Sacramento-San Joaquin Delta watershed.  It was anticipated the revised Emergency Regulation would lead to new curtailments reaching BBID’s post-1914 right, serving the West Side Service Area, as well as BBID’s pre-1914 senior water right, serving the Byron and Bethany service areas.

However, BBID’s water rights were not included in a new round of curtailments announced this week. In an update, the State Water Resources Control Board said, in part:

“After consultation with and the concurrence of the Delta Watermaster, and consistent with the technical assumptions regarding water unavailability in the Legal Delta outlined in methodology documents released on June 27, 2022, curtailments remain in place for certain rights within the Legal Delta. Although the methodology indicates that water is unavailable for appropriative water right holders in the Legal Delta with a priority date of 1908 or later, curtailments in the Legal Delta will remain unchanged pending further discussion between the Division of Water Rights and the Office of the Delta Watermaster.”

Earlier in July and in the span of less than one week, the State Board issued, then rescinded curtailment with little notice and no explanation.

Before the State Board rescinded the last curtailment order, BBID’s legal team filed a request for a Temporary Restraining Order, arguing the order was issued without due process and is not supported by adequate evidence. BBID also argues the methodology used by the State Board to determine water unavailability in the Legal Delta is fatally flawed, and cannot support curtailment of BBID’s water rights. Since last summer, and on numerous occasions, the District’s team of legal, engineering, and hydrology experts offered comments and possible solutions to the State Board to refine the methodology and improve its accuracy.  Despite these comments, and those made by other Delta stakeholders, significant problems remain with the methodology and it remains unsuitable for determination of curtailments in the Delta.

As this evolving situation unfolds, the District will continue providing regular updates to ensure customers are informed. In the meantime, BBID continues to secure alternative water supplies and vigorously defend its water rights.

BBID Water Supply Update – July 2022

Byron, CA (July 25, 2022) – Due to recent State Water Resources Control Board (State Board) actions, the Byron-Bethany Irrigation District (“BBID” or “District”) is advising its customers of potential future curtailment of the District’s water rights, which may come this summer.

At its regular July meeting, the State Board approved and adopted a revised Emergency Regulation regarding water use and curtailment in the Sacramento-San Joaquin Delta watershed.  The revised Emergency Regulation will now be considered by the Office of Administrative Law (OAL) before it becomes law. If enacted, the revised Emergency Regulation will likely lead to another, deeper round of curtailments in mid-August.  We anticipate such curtailments reaching BBID’s post-1914 right, serving the West Side Service Area, as well as BBID’s pre-1914 senior water right, serving the Byron and Bethany service areas.

Earlier this month and in the span of less than one week, the State Board issued, then rescinded curtailment with little notice and no explanation.

Before the State Board rescinded the last curtailment order, BBID’s legal team filed a request for a Temporary Restraining Order, arguing the order was issued without due process and is not supported by adequate evidence. BBID also argues the methodology used by the State Board to determine water unavailability is fatally flawed, and cannot support curtailment of BBID’s water rights. Since last summer, and on numerous occasions, the District’s team of legal, engineering, and hydrology experts offered comments and possible solutions to the State Board to refine the methodology and improve its accuracy.  Despite these comments, and those made by other Delta stakeholders, significant problems remain with the methodology and it remains unsuitable for determination of curtailments in the Delta.

The District’s TRO is still pending before a Sacramento County Superior Court, and the hearing on it is scheduled for next week—July 29.  If the judge grants BBID’s request, future curtailments this summer are unlikely.  This, however, depends on the relief the judge provides.  The District commits to providing additional updates with any developments in this rapidly evolving situation.

In the meantime, BBID continues to secure alternative water supplies and vigorously defending its water rights.

BBID Water Supply Update – June 2022

Byron, CA (June 15, 2022) – The Byron-Bethany Irrigation District (BBID) has an important water supply update for its customers. On June 7, the State Water Resources Control Board’s Division of Water Rights issued an update earlier this month advising that, witha the exception of junior water rights with Term-91, water rights in the Legal Delta will not be curtailed.  Specifically, the notice states in pertinent part the following:

  1. No curtailment of rights and claims within the Legal Delta. In coordination with the Office of the Delta Watermaster, Division of Water Rights staff are in the process of updating several technical assumptions regarding water unavailability within the Legal Delta. Pending completion of those updates, rights and claims within the Legal Delta will not be curtailed pursuant to the Drought Emergency Regulation.  Term 91 curtailments will continue to apply to rights within the Legal Delta containing Term 91.  (Bold in the original.)

All BBID water rights, including the pre-1914 water right that provides for much of the District’s service area, are in the Legal Delta.  The post-1914 water right now held by BBID (formerly, the West Side Irrigation post-1914 water right) does not contain Term 91.

BBID’s team of legal, engineering, and hydrology experts continue to work with Board staff to resolve latent defects with the Water Unavailability Methodology for the Delta Watershed used by the Board to determine water unavailability in the Legal Delta.

West Side Service Area: This area, formerly the West Side Irrigation District, is served by a post-1914 junior water right. This water right is currently not curtailed. However, to be prudent and in anticipation of possible curtailments, the BBID Board of Directors ratified a 50% water delivery schedule for the West Side Service Area, effective July.

Central Valley Project (CVP) Service Area: Currently, South-of-Delta CVP contractors including BBID have a 0% allocation. In April, the U.S. Bureau of Reclamation reduced the initial 25% M&I allocation to Public Health & Safety.

BBID continues to seek alternative water supplies and, when necessary, vigorously defend its water rights. The District will provide water supply updates as conditions change.

Water Supply Update – April 2022

Byron, CA (April 15, 2022) – As dry conditions persist across California, the Byron-Bethany Irrigation District (BBID) is establishing a regular water supply update to keep its customers informed.

  • Pre-1914 (Senior) Water Right: Currently, BBID’s pre-1914 senior water right is not curtailed. That senior water right provides for reliable water deliveries across much of the District’s service area. However, it is anticipated that curtailments could occur this summer due to drought conditions.
  • West Side Service Area: This area, formerly the West Side Irrigation District, is served by a post-1914 junior water right. This water right is currently not curtailed. Again, it is anticipated that curtailments could occur this summer.
  • Central Valley Project (CVP) Service Area: Currently, South-of-Delta CVP contractors including BBID have a 0% allocation. Earlier this month, the U.S. Bureau of Reclamation reduced the initial 25% M&I allocation to Public Health & Safety.

BBID will continue to seek alternative water supplies and, when necessary, vigorously defend its water rights. The District and its expert consultants are engaged with the State Water Resources Control Board and the Delta Watermaster to help refine the methodology that provides the basis for water right curtailments.

In the coming weeks and months, the District will provide water supply updates as conditions change.
