Lake Arrowhead Csd Ca3610005 Woods

What Lake Arrowhead Csd Ca3610005 Woods filed with DWR about the water it produced and the water it billed for, 2017–2025 — and what the filing does and does not let anyone verify.

Apparent loss is valued at this utility's own reported retail price of water. Real loss is NOT included — DWR publishes a variable production cost whose unit it does not declare, so no dollar figure is put on the leaked water. The real recoverable total is higher than this by an amount this filing does not let anyone state.

Balance check
inapplicable
DWR derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows

14.3% non-revenue water in FY2025, higher than 80% of the 141 California systems that filed that year.

What it charges

$68.05 a month for a household using 6 hundred cubic feet — 4,488 gallons — and $195.90 at 17,952 gallons. Computed from the fixed charge and the tiers this system filed for reporting year 2025, not read off a rate sheet.

The fixed charge is $54.47 a month before any water is used. Billing is monthly, quoted in hundred cubic feet.

From data/archive/ca-ear-rates/2026-09-09-6eba0fd85f1f-section8-charges.jsonl, extracted 2026-09-09 from the Board's published section 8a file. That file has no cells: a value is found by the system identifier and the question abbreviation above.

The Board also publishes an undocumented charge field for this volume. Our figure reproduces it to the cent, which is what establishes that the field is a bill at this volume for systems like this one.

This is what the system reported for reporting year 2025. It is not necessarily the rate in force today, and nothing in the filing says whether it has since changed.

Compliance record

EPA's Safe Drinking Water Information System carries no violation for this system in the 2026Q2 download.

That is a statement about the record. SDWIS is a state-to-EPA reporting pipeline and its completeness varies by primacy agency and by quarter, so an empty record is not the same as a system that has never been in violation.

Who filed this audit

Lake Arrowhead Community Services District filed 3 separate audits for FY2025, one for each public water system it operates, and this page is one of them. California keys its water loss export on the filing organization and not on the system, so a count of California audits is not a count of independent utilities. Lake Arrowhead Community Services District made one set of decisions and filed it 3 times. Read any statewide figure with that in mind, including the ones on this site.

Every figure on this page is read from DWR's published export as this site holds it: a 184-column extract of DWR's 190-column file. Six columns naming individuals, including the contact and the third-party validator, are removed before the bytes are committed, so the click path behind each figure lands on the extract and not on DWR's original. The column letters differ from DWR's for that reason.

Water balance, FY2025 · 398.1 MG system input
Billed 341.4 MG Unbilled authorized 3.58 MG Apparent loss 3.44 MG Real loss 49.7 MG

DWR derives water losses from system input minus authorized consumption, so these parts sum to the whole on every filing. What a filing can get wrong is which of these numbers were measured.
