Topology cross-check: 12 parent disagreements, 20 sizable streams not on this network (vs DWR's route framework — under review)

This flow network was built mechanically; DWR's Source Water Route Framework disagrees with it in the places below. Each row is a question a human reviewer has not yet answered — not an error verdict. Checked 36 streams, 24 agree. Know this water? Tell us →

⚠ This district is administered as part of the deployed South Platte product, whose modeled mainstem currently runs Denver gage → Greeley (the WD2 reach). The schematic and mass balance shown here are that combined product — this district's own upstream reach is not yet independently modeled. Calls, stations, and rights data ARE district-specific.

Evolution of the network

This year, in context

In the weeks around 2026-08-30 (the newest reading on file), flows at the 121 ranked gages are running at a median 78% of their own long-term norm for this window — 79 below a typical year, 42 at or above. Driest relative to its record: WALKER RESERVOIR OUTLET, ranking 1st lowest of 5 years.

How this comparison is made

Each gage's mean flow over the 3 days either side of 2026-08-30, compared with the same window in every year of its own record — so a gage is only ever measured against itself, and gages with no record in the window are counted out rather than guessed.

Gage flow trend & changepoints

What counts as a trend here

Computed 2026-08-31 06:07 from 268 gage(s) with cached period-of-record data. The series is each gage's annual mean flow in cfs (years with ≥300 days of record). Mann-Kendall (trend, with the Hamed–Rao correction for serial correlation — persistence can otherwise fake significance) and Pettitt (changepoint) both require at least 8 years spanning at least 10 years of record. A gage below that reports no signal — which is not the same as “no change.” The %-per-decade figure is the same Sen slope divided by the gage's median annual flow, for comparing across streams of very different size; it is omitted for near-ephemeral channels where the median is too small to divide by honestly.

Of the 268 gages with enough record, 16 are trending down and 15 up, and 21 carry a detected shift. The clearest is South Platte River near Lake George, its annual mean flow changing +7.54 cfs per decade (+8.2% of its median annual flow) over 96 years (p<0.0001). The other 233 show no clear signal either way. 1 transbasin gage meters imported or exported water — marked ⇆ below and kept out of these counts, because that flow is an operator's decision, not the basin's hydrology (all transbasin diversions).

What drought has cost here

Since 1991, federal crop insurance has paid $447,607,406 in drought-caused claims across Adams, Arapahoe, Boulder, Clear Creek, Denver, Douglas, Jefferson, Logan, Morgan, Park, Pueblo, Sedgwick, Washington, Weld counties — 38.4% of all insured crop losses there. The worst year was 2022 ($122,140,711).

USDA crop-insurance indemnities where the recorded cause of loss is drought, summed over the counties this district's gages sit in. Counties overlap water districts imperfectly, and insured-crop claims are a floor on drought damage, not a total. Source: USDA RMA cause-of-loss files.

⚠️ 6 gages flagged: their records may have quietly shifted against their neighbours, so treat their trends with caution.

How drift is detected

Every gage's annual flows are compared against each neighbour's as a double-mass curve (Searcy & Hardison, USGS WSP 1541-B); a Pettitt step test looks for a break in the ratio. A gage is flagged only when the breaks AGREE across its references, and a break against an already-suspect gage is never counted against a healthy one. A double-mass break means the ratio between two gages changed, not that either gage is faulty: a new diversion, a reservoir, or an import changes that ratio exactly as a rating shift does. Screening aid for expert review, never a measurement verdict.

233 other gage(s) show no significant trend or changepoint (not shown).

2 of those show a significant trend once extended backwards from a retired neighbour's record: So. Platte River below Brush Cr. near Trumbull (101 yr, increasing); North Fork South Platte River at Grant (87 yr, increasing). Those are reconstructions, not measurements — each gage's page shows both.

How the measurement network itself changed

This basin was not always measured the way it is today — the API-era record is dense and recent, the early record sparse. 198 gage(s) and 689 structure(s) report in 2026, but structure reporting only reached half its modern level around ~1973. Every historical claim below is checked against this: long-term shifts that co-move with the growth of the network carry an explicit measurement-evolution caution, and abandonment screens whose idleness begins before the modern reporting era are flagged †.

Mass-balance (network closure) trend

Structure divrec-history backfill coverage as of the last check: 21% of 2166 schematic-relevant structures. 0 year(s) clear the 30% coverage gate so far -- the trend activates automatically once qualifying years span a full decade. No action needed; the nightly backfill keeps extending the record.

Reach gain/loss shifts (1950–2025)

Mass-balance kinks computed for every summer month back to 1950 (1323 reach-snapshots) — which reaches gain or lose water, and how that has shifted across decades. Each shift is cross-checked against the observation record above: as more diversions became metered, "unaccounted" water shrinks mechanically, which can masquerade as a hydrologic shift.

SOUTH PLATTE RIVER AT FORT LUPTON, CO.: reach shifted from +86 cfs to +539 cfs summer mean (more gaining, p=0.000, 70 yr) [sedimentary plains/foothills: moderate groundwater connectivity -- gain/loss shifts can be real aquifer response; corroborate with nearby well records] [measurement-evolution caution: this shift co-moves with the growth of the gage/metering network (rho=0.6) -- part of it may be unaccounted water becoming accounted, not hydrologic change] [76 alluvial wells within 2 mi of the gage; pooled water table +1.1 ft (1929–2025, no_trend)]
FIRST CR BEL BUCKLEY RD, AT ROCKY MTN ARSENAL, CO: reach shifted from -30 cfs to -16 cfs summer mean (more gaining, p=0.049, 14 yr) [sedimentary plains/foothills: moderate groundwater connectivity -- gain/loss shifts can be real aquifer response; corroborate with nearby well records] [measurement-evolution caution: this shift co-moves with the growth of the gage/metering network (rho=0.53) -- part of it may be unaccounted water becoming accounted, not hydrologic change]

Cross-gage pattern fingerprint

Over the 102-year window with full coverage (1925–2026), the dominant shared pattern across 3 gage(s) explains 82% of year-to-year variance (almost certainly a basin-wide climate/snowpack driver).

All gages in this window move with the shared pattern -- no localized outlier.

176,163 water-level measurements across 8961 monitored well(s) — 3556 alluvial, 2848 bedrock — plus 170 administered well(s) reporting metered pumping.

What is being counted

Observation wells and pumping wells are different populations and are never conflated: water levels come from monitored observation wells, and metered pumping comes from administered wells reporting through diversion records. Click any well to chart its own record.

How the surfaces are built, and what they are not

Alluvial water table on top, Denver Basin members (Dawson, Denver, Arapahoe, Laramie–Fox Hills) stacked beneath where measured, interpolated from measured water levels. Units are never mixed; a surface exists only inside its own unit's well coverage, with no extrapolation; thin epochs are suppressed and say why. Vertical scale is exaggerated for readability and z is head elevation in feet. These are measured heads, not a calibrated groundwater model.

Stream corridors — the surface connection

Where a reach's gain or loss has shifted, the wells within two miles of its anchoring gage and what their water table did over the same era.

How the corridor is assembled

For each reach whose gain/loss has shifted (Trends tab): the wells within 2 miles of its anchoring gage, their pooled water-table history over the same era, and an advisory Glover screen of lagged stream depletion from nearby metered pumping. v1 proximity = distance to the reach's anchoring gage; segment-based reach join is a flagged upgrade.

SOUTH PLATTE RIVER AT FORT LUPTON, CO.: 76 alluvial well(s) nearby; pooled water table +1.1 ft (1929–2025, no_trend, p=0.257). Glover screen: 3.2 cfs of nearby metered alluvial pumping → est. lagged depletion 2.8–3.1 cfs (uncalibrated T/S ranges; flagged for SPDSS calibration, AWAS cross-check, and expert review — DWR's AWAS is the authority).

FIRST CR BEL BUCKLEY RD, AT ROCKY MTN ARSENAL, CO: 62 alluvial well(s) nearby

Wells labeled by administrative world before anything else is said about them: tributary alluvium participates in the priority system; designated-basin and Denver Basin bedrock aquifers are governed differently and are excluded from stream-connection reasoning. Read bedrock declines differently too: deep bedrock aquifers recharge negligibly on human timescales, so a falling bedrock level is storage mining — effectively permanent — not a drought response that a wet year undoes. All screens advisory.

284 reservoir(s) with 254,263 storage measurement(s), 1950–2025. Basin storage as of 2024-10-31 (the record's own end — reservoir records publish ~annually): 419,331 AF across 85 reservoir(s).

Why storage matters to the flow network

Storage change is real water the mass balance must credit — a losing reach beside a filling reservoir isn't losing water, it's banking it.

Reservoir map — how full is each vessel?

What “full” is measured against

Bubble size is proportional to a reservoir's record-high storage. Fill is its last recorded storage as a share of its surveyed capacity (USACE National Inventory of Dams) where a confident NID match exists — the tooltip names the matched dam — and as a share of its own record high otherwise. A wrong capacity would be worse than an honest record high, so only confident joins upgrade.

A dashed teal ring marks reservoirs reporting live DWR telemetry: their fill reflects yesterday's storage, is drawn as a dotted tail on charts, and is treated as provisional until the next verified HydroBase snapshot supersedes it.

A dashed red ring marks a dam under an active storage restriction from DWR's Dam Safety branch — the State Engineer has limited how much it may legally store, so a low fill can be an order, not a drought. Hazard class and inspection condition come from the same record, joined only where the dam carries this reservoir's WDID or a confident NID match — a wrong dam's restriction would be worse than none shown.

Snow-water equivalent, WY2026

No snow on the ground — normal for the date; the snow year begins in October. The chart shows the full water year just ending.

SNOTEL site	Elev (ft)	SWE (in)	Median (in)	% of median	Typical peak
Jackwhacker Gulch	11030	0.3	0.0	—	April 25 (14.4 in)

NRCS SNOTEL, daily. Sites are assigned to the district whose boundary contains them — the snow that feeds this district can also sit in a neighboring headwater district.

Two ways a snow year goes wrong (1999–2026)

A bad snow year here comes in two flavors (both called snow drought), and the river feels them differently. In 7 of the last 28 winters the snow never came — the pack peaked below 80% of its median. In 0 more, the snow came but left early — a near-normal peak melted out two weeks or more ahead of its usual date, sending the water down before the season needed it. This year was one of the dry ones: the pack peaked at 50% of median.

The snow never came: 2002, 2004, 2005, 2010, 2012, 2022, 2026.

Computed by this site from 1 SNOTEL site’ full daily records (NRCS AWDB, back to 1999). Each year is measured against each site’s own multi-decade median — not the 1991–2020 normal the chart above uses — so the 1980s grade against a fair baseline. Peak and melt-out need 85% of the season’s days on the record; thin years are dropped, not guessed. Derived from snow measurements alone — it cannot tell dry-from-warm causes apart, only what the snowpack did.

Runoff outlook — Cheesman Lake Inflow

NRCS's final issue (2026-06-01) calls it even odds that at least 31 kAF arrives over 06-01 to 09-30 — 40% of a normal season; almost certainly at least 16, probably not more than 45. New forecasts begin in January. How to read these numbers →

Decreed rights on this network run from 1859-03-01 to 2024-11-18. Of the 20 structures with a yield estimate, the median one’s senior right was in priority 55% of a median irrigation season and 35% in a dry one. 25 abandonment screens and 295 compliance flags are listed below as leads for review — a screen is not an abandonment and a flag is not a violation.

Rights on file: 28304 across 21881 structure(s); 1693 structure(s) carry 3253 court-case references. Advisory reading aids on public DWR data — not administrative or legal conclusions.

Is the river getting harder to divert from?

Over 2012–2025, none of the three measures of administration (days under call, calls set, seniority of the controlling call) shows a significant trend — the river is being administered about as it was.

The three measures, year by year

One row per whole calendar year inside the call record's coverage (14 years); partly-covered years are omitted rather than reported as quiet. Trend is Mann-Kendall with the same significance gate as every other trend on this site. Counted from DWR's published call record, which begins in the early 2000s: earlier years are absent, not quiet. A rise in the number of calls set can also reflect how finely an administrator records one episode, which is why days under call -- insensitive to that -- is the component to read first. Advisory summary of the public record, not an administrative finding.

What the water is for — decade by decade

Of the water this district's structures diverted, the share whose decree includes municipal supply moved from 79% in the 1970s to 84% in the 2020s.

The decades, and how the attribution works

Every structure's recorded diversions, attributed to what its water was decreed FOR in that year. Colorado decrees are usually multi-use (“IRR MUN COM IND…”), so these are shares of water whose decree includes a use — non-exclusive, and they do not sum to 100%. A right that adds municipal use in 1988 counts toward it only after. Decades before this basin's modern reporting era are flagged: their records are thinner, not their rivers drier. Shares of recorded diverted volume, not of water rights or of acreage. A structure's water is attributed only to uses decreed by that year, so a later municipal decree cannot reach back and recolour earlier diversions. Families overlap -- a ditch decreed for irrigation and municipal supply counts in both -- so shares can sum past 100%. Volume the record cannot attribute is reported separately, never distributed.

Right yield — how often could these rights actually divert?

Share of irrigation-season days each structure's rights were not called out, derived from the 22-year district-scoped call record (senior right = floor, junior right = ceiling constraint). Call-record-derived; DWR's own analysis governs where available.

Abandonment radar (25 screens)

Absolute rights with 10+ years of no recorded diversions. Screens only — storage, alternate points, and plan operations can explain nonuse lawfully. And diversion REPORTING itself only reached its modern level ~1973 — idleness that begins before then may be unreported use, not nonuse (flagged † below).

Active substitute water supply plans in this district

Temporary State Engineer approvals to divert out of priority (37-92-308 / 37-90-137). A structure operating under one behaves differently under a call than its decreed rights alone suggest — the priority tables above don't know about these; this list does.

Showing 25 of 64 plans — the rest are on DWR’s register.

If a call were placed at a given seniority, which structures in this basin would be out of priority, and how much of their decreed rate would be curtailed? Computed from this basin's cached decrees.

What this does and doesn't model. Seniority arithmetic only: every right junior to the call is treated as curtailed. It does not model reach applicability — structures downstream of the calling point are not administered by it — and it applies no futile-call judgment. Read it as “who is junior to this date, and by how much,” not as a prediction of what the Division Engineer would actually order.

Pick a calling right

Real decrees from this basin, ordered by administration number — that is, by actual seniority. The years will look out of order, and that is correct: an administration number encodes the adjudication date as well as the appropriation date, so a right appropriated in 1970 can be administered ahead of one from 1950. A senior call curtails almost everything; a junior one curtails almost nothing.

Or enter an administration number directly

Administration number

DWR administration numbers encode appropriation and adjudication dates; lower is more senior.
