# Cachuma Project Publisher: CapexCue Canonical dossier: Dossier reference: release 1 (23cd2c05-885e-4dcf-9bed-6e7dc5788fb0) Released project intelligence Oldest supporting observation: 2026-10-03T09:37:28.818972+00:00 Dossier released: 2026-10-16T16:29:12.837787+00:00 Source report dates and capture dates are listed per fact below; neither establishes an event date. ## Project summary The Bureau of Reclamation page identifies the Cachuma Project in California. It describes Bradbury Dam on the Santa Ynez River, about 25 miles northwest of Santa Barbara, storing river floodwaters that are conveyed through the Tecolote Tunnel and South Coast Conduit to South Coast agricultural and municipal users, including Santa Barbara. The page describes a 6.4-mile tunnel, a 24-mile conduit and four regulating reservoirs. It also reports that Glen Anne Reservoir was permanently restricted on August 19, 2002, because of seismic-related risks, and is maintained but no longer operated. The page reports estimated annual evaporation losses of 16,000 acre-feet and describes sediment buildup despite mitigation efforts. ## Evidence limits and unknowns - The supplied page context gives no publication or as-of date. In particular, it does not date its present-tense description of Glen Anne Reservoir’s status. - The supplied page does not identify a current project package, budget or financing, procurement status, current capital works, or next milestone; its Plan and Other sections contain no text. - The supplied evidence covers the page’s visible text, not the linked Cachuma Project History document, which was not acquired or interpreted. Current purchasing availability: unknown. Source-dated plans do not establish current progress or available supplier packages. ## Project metadata Country: United States Region: North America Physical assets: Not classified Derived from the exact released evidence; unresolved fields remain unclassified. ## Project category Water and environment Derived from the reviewed scope statement; delivery stage remains unclassified. An integrated system comprising Bradbury Dam and Lake Cachuma; the 6.4-mile Tecolote Tunnel; the 24-mile South Coast Conduit and four regulating reservoirs; and localized distribution systems with lateral pipelines and pumping plants. The Carpinteria system also includes an elevated 50,000-gallon tank. The page gives Bradbury Dam as 279 feet high from the bottom of the cutoff trench to the top, and Lake Cachuma as having a capacity of 193,300 acre-feet and a 42-mile shoreline.

It separately dates construction of Bradbury Dam and the South Coast Conduit to 1950–1953, the regulating reservoirs to 1951–1954, and distribution systems to 1952–1956, with those systems operable by early 1956. The page also reports that Glen Anne Reservoir was placed under permanent restriction on August 19, 2002, due to seismic-related risks, and says it is maintained but no longer operated.

The system serves the South Coast area, including Santa Barbara and water districts in Goleta, Montecito, Summerland and Carpinteria.

The page says each district for which a system was built is responsible for its operation and maintenance, and member units acting through the Cachuma Operation and Maintenance Board operate the rest of the project.
