The well-permit cells in view, as a table

Each row is one ~1-mile cell (0.02°) with the permits the file spots inside it, split into water-supply permits and monitoring holes (DWR’s two monitoring categories: drilled to look at the water, not to pump it). These are permits, not wells: a permit is a piece of paper, and the file does not say which were drilled. Spotting is the file’s own, about a mile at best, which is why the cells are no finer.

This year, in context

In the weeks around 2026-09-27 (the newest reading on file), flows at the 28 ranked gages are running at a median 43% of their own long-term norm for this window — 22 below a typical year, 6 at or above. Driest relative to its record: NEW CACHE LOWER SAND CREEK RETURN, ranking 1st lowest of 7 years.

How this comparison is made

Each gage's mean flow over the 3 days either side of 2026-09-27, 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 2026-10-11 19:42 from 51 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 51 gages with enough record, 3 are trending down and 2 up, and 3 carry a detected shift. The clearest is Fort Morgan Canal near Wiggins, its annual mean flow changing -9.42 cfs per decade (-9.3% of its median annual flow) over 32 years (p=0.0010). The other 46 show no clear signal either way.

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. 37 gage(s) and 459 structure(s) report in 2026, but structure reporting only reached half its modern level around ~2009. 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: 5% of 6818 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 (1950–2026)

Mass-balance kinks computed for every summer month back to 1950 (2347 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.

ILLINOIS DITCH: reach shifted from -1474 cfs to -513 cfs summer mean (more gaining, p=0.008, 16 yr) [alluvial valley: real alluvial aquifer -- a decades-long shift toward losing is the classic signature of alluvial pumping and urbanization] [19 alluvial wells within 2 mi of the gage; pooled water table +0.1 ft (1966–2026, no_trend)]
SOUTH PLATTE RIVER NEAR WELDONA, CO: reach shifted from -247 cfs to +530 cfs summer mean (more gaining, p=0.000, 74 yr) [alluvial valley: real alluvial aquifer -- a decades-long shift toward losing is the classic signature of alluvial pumping and urbanization] [measurement-evolution caution: this shift co-moves with the growth of the gage/metering network (rho=0.74) -- part of it may be unaccounted water becoming accounted, not hydrologic change] [28 alluvial wells within 2 mi of the gage; pooled water table -3.3 ft (1949–2025, no_trend)]

Cross-gage pattern fingerprint

Over the 39-year window with full coverage (1988–2026), the dominant shared pattern across 3 gage(s) explains 97% 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.

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.

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.

Permits issued here, by year

40,308 located water-supply permits with an issue date, 1900 to 2026; half of them had been issued by 1999, and the busiest year was 2001 with 1,212. The district’s 5,015 monitoring holes are counted apart: they are drilled to look, not to pump. A permit is not a well, and the year is the date the paper was issued, not a drilling date.

Every district in the file on one scale · the whole file, one year at a time · Plate 4 of the Driller’s Atlas.

What drillers reached, township by township

199 PLSS townships here where at least 5 water-supply permits naming the same aquifer filed a depth (31,369 permits in all; the 24 most-drilled are drawn, every one is in the table). Each column is one township, six miles square, on one scale to 2,600 ft below ground: a faint lane spans the 10th to 90th percentile of where the permits naming that aquifer stopped, the solid band their screens, the tick the median. This is the permit file’s view of the ground — the aquifer is the name the driller wrote, the band is where those holes ended — not a geologic map, and a township is as fine as it gets. Monitoring holes are left out. Columns are drawn to 3,000 ft at most; 1 band here runs deeper and is drawn to the bottom edge with an arrow, the numbers as filed in the table: T3N R55W other named (5 permits, 90th percentile 6,508 ft). 28 of these townships straddle a district line and are filed here because most of their permits are.

The Driller’s Atlas · Plate 2 A cross-section nobody surveyed

Every permitted well within a few miles of the line, drawn from the ground to its drilled depth as the driller filed it. The bright part of each stroke is the perforated casing — where the well actually takes water — coloured by the aquifer named on the permit. Nobody arranged these; the aquifers arrange themselves.

Line Corridor

Hover or arrow through the strokes to read a well.

The same corridor as a table


Miles from A	Wells drawn	Median depth (ft)	With a screen	Most-named aquifer	No depth filed	Ground, ft above sea level (median)

Bins run from end A to end B of the line. “Most-named aquifer” is the family most often named on permits in the bin, with its count; permits naming no aquifer are the majority of the file and are not a family.

Reservoirs

Source DWR administrative record · verify at DWR structure records ↗

38 reservoir(s) with 68,625 storage measurement(s), 1950–2026. Basin storage as of 2025-10-31 (the record's own end — reservoir records publish ~annually): 35,243 AF across 13 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.

Right now

This is the 20th-driest week 39 in 124 years of record at SOUTH PLATTE RIVER NEAR KERSEY, CO (as of 2026-09-21; this week’s flow sits at the 16th percentile for the date). On this week’s US Drought Monitor, Weld County is 7% in D4 exceptional drought (2026-10-06).

Every year since 1901, week by week

Each thin row is a year at SOUTH PLATTE RIVER NEAR KERSEY, CO; each cell is one week’s flow ranked against the same calendar week of every other year — warm means dry for the date, blue wet, so seasonality cancels and droughts appear as warm bands. Gaps are missing record, never a dry river. Click a year to reconstruct it on the Historical tab.

This year against its analogs

Over the 39 weeks recorded so far, 2026’s weekly trace most resembles 1908 (mean gap 11.8 percentile points; next closest 1950 (12.2), 1932 (13.2)). The analog’s remainder is drawn as context — its ending is what happened to it, not a forecast for this year.

The Drought Monitor’s view since 2000

Mean share of area in each class across Adams, El Paso, Elbert, Morgan, Washington, Weld counties — the counties this district’s gages sit in, which overlap the district imperfectly. The Drought Monitor weighs soils, vegetation and local reports; it is CONTEXT beside the river’s own record above, not the water-rights picture.

Detected mechanically: the 26-week smoothed percentile below the 30th for at least 20 weeks; recovered on regaining the 50th. The water-table clock compares each monitoring well against its own pre-drought median (the 3 years before onset) and dates the year the median well got back — the aquifer remembers longest, and “still below” is a finding, not a gap. The knobs are stated because the episode list depends on them — a different reasonable choice merges or splits episodes at the edges. Names are attached where an episode overlaps a drought Colorado already talks about.

What drought has cost here

Since 1991, federal crop insurance has paid $332,268,749 in drought-caused claims across Adams, El Paso, Elbert, Morgan, Washington, Weld counties — 38.3% of all insured crop losses there. The worst year was 2022 ($81,587,616).

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.

When this basin claimed its water

Every bar is a year’s new appropriations (8,493 rights across 124 years of shared record), colored by that year’s wetness from the barcode above. Here the correlation is -0.1 — essentially no wet-dry pattern; here, law and settlement set the pace, not the weather. Across the state both behaviors exist: ephemeral southwest basins file after wet demonstrations, transbasin-source basins under drought — and the biggest statewide filing waves sat in the 1950s drought and after 2002, not in the wet 1980s–90s.

Appropriation dates are the CLAIMED initiation of a right, not the courthouse filing date; the record is survivor-biased (abandoned claims are absent, so failed dry-era scrambles are undercounted); and the big 1960s and 2000s spikes sit on legal events — the pre-1969-Act adjudication era and 2000s legislation — not on weather. A correlation here is a description, never a cause.

New to how a dry winter becomes a call on the river? Anatomy of a drought walks the chain in four minutes — snow to rivers to reservoirs to calls to the water table.

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.

Water quality

The water itself, in this district

Four registers, each on its own schedule: what USGS sensors read right now, where samples have been taken, which stretches the state lists as impaired, and how the tap water of the systems here stands with EPA. None is a DWR record; each links its own page.

Right now

Where water has been sampled

Source Register of another agency · fetched 2026-10-08 · verify at Water Quality Portal ↗

The portal lists 8,828 sampling stations in this district's watersheds (Middle South Platte-Cherry Creek 10190003, 21% of the district; Bijou 10190011, 19% of the district; Beaver 10190013, 16% of the district; Middle South Platte-Sterling 10190012, 15% of the district; Crow 10190009, 12% of the district; Kiowa 10190010, 10% of the district; Lone Tree-Owl 10190008, 6% of the district), of which 274 reported a sample in the last 5 years on the state and tribal side (USGS activity is in the station count, not in that figure). Most active: Colorado Dept. of Public Health & Environment-WQCD (162), USGS Colorado Water Science Center (47), Metro Water Recovery (formerly Metro Wastewater Reclamation District) (45). Most-sampled groups: Inorganics, Major, Metals, Physical, Nutrient, Organics, Pesticide. Every station as a file ↗

Results themselves are not fetched here; USGS samples added after March 2024 may not be in the portal's legacy profiles yet.

Drinking water

Source Register of another agency · fetched 2026-10-07 · verify at EPA SDWIS ↗

38 community systems touch this district. None carries an open health-based violation on EPA's record. EPA sampled 8 of them for PFAS in 2023–25; none had PFOA or PFOS at or above the 2024 limit.

System	Serves	EPA record	PFAS (UCMR 5)	Lead, latest 90th pct
DENVER WATER BOARD	1,287,000	11 of 12 quarters with a violation	none detected	0.0036 mg/L

ELIZABETH TOWN OF	4,523	clean, last 12 quarters	not sampled	0.004 mg/L

and 28 more; the full directory filters by district.

EPA's record carries violations and lead/copper percentiles; nitrate and disinfection by-product results are not in it. UCMR 5 samples are monitoring, not compliance, and the 2024 PFOA/PFOS limits equal its reporting limit, so any detection of those two is at or above them.

Impaired waters

Source Register of another agency · verify at EPA ATTAINS ↗

The state's 303(d) impaired-waters list has not been joined to this basin's own watershed boundary yet, so nothing is shown rather than a guess; the basins with a join carry the full list here. Why the join is geometry, not a name match.

Call cascade

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.
