Where this page's figures come from
Generated 2026-09-17 05:15 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260707 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (956f090) — every figure regenerates from this named code version and data image.
Where this structure is measured
| Gage | Flowing now | Record | How we know |
|---|---|---|---|
| CITY OF BRIGHTON SEWER OUTFLOW BRISEWCO | 0.0 cfs | 2021–2024, 500 days | DWR telemetry mapping |
A green link is DWR's own: either its telemetry inventory maps this WDID to that station, or the station is named for this WDID (0700553 → 0700553A). An amber one is ours — the station sits within 250 m and shares a distinctive word with this structure's name, which is a strong hint rather than a DWR statement that this gage meters this structure. Wrong? Tell us.
Flowing now
0.0 cfs last reported 2024-02-11 10:45
Zero is a real reading: the gage is reporting, and it says this structure is not diverting right now.
This station has not reported in over a day, so treat the number as the last thing it said, not as now.
Provisional 15-minute telemetry from BRISEWCO ↗ (CITY OF BRIGHTON SEWER OUTFLOW). Raw, not the approved record — it is never merged into the diversion history below. DWR publishes the official diversion record after the water year closes and is approved, which is why that record ends months back while this reads minutes ago.
In short
In a median year over its last 15 recorded years it diverts 802 acre-feet. That use is falling by about 118.1 acre-feet a year over 15 years (p=0.025770400045874275).
Assembled from the figures on this page — every number above is checked against them before it is shown (5 checked). The detail, with its method, is in the cards below.

What is in the bundle
rights.csv— every decreed right, most senior first, with admin numbers, dates, amounts, uses and case numbers.annual_use.csv— recorded diversion by year, with releases accounted separately.curtailment_now.csv— each right's current priority status and how often it was out across analog years.court_cases.csv— the cases attached to its rights.co_parties.csv— the other structures that were parties to those cases. Not available anywhere else.call_climatology.csv— how often each right has been out of priority by week of season, with confidence intervals and the seasons the record could actually judge.README.txt— provenance, methods, limits, disclaimer, and links back to DWR's own records for verification.

Which of its rights are out of priority?
Not computable for this structure: no decreed right on file, so there is no priority to test.
Recorded use (last 15 years on record)
Years far under the decreed amount? That gap has a name — paper water vs. wet water, explained on this structure.
In a median year this structure has a recorded diversion of 802 AF. Its most recent year on record, 2025, came in at 0 AF — 0% of that, and 1st lowest of the 15 years with a recorded volume.
This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.
| Year | Diverted (AFA volume: one acre covered a foot deep, about 326,000 gallons -- roughly a suburban household's outdoor use for a year.) | Compared with its own record | Released (AF) | Days recorded | Peak (cfs) |

How good is our record of it?
Grade B (7/10 points) — the components below are the finding; the letter alone is not.
The rubric, component by component
| Check | State | Detail |
|---|---|---|
| identity | complete | name, type, and water source all on file |
| decreed rights | absent | no water rights cached for this WDID |
| diversion record | present | 4254 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | continuous | 90% of the irrigation seasons in 2003-2025 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
