The pages of this site are free and will stay free : an official fact belongs to no one. What is sold here is the compilation work — extracting the Colorado well permit register, reconciling it, dating it, and delivering it in a usable form.
Why the stream, not the snapshot
This register moves every day. Permits are issued, wells are reported as constructed, permits lapse. A snapshot records where the register stood on one morning; the difference between two mornings is what a portfolio holder wants to be told about — particularly a permit that has just expired.
What is in it
Every field below is measured on the delivered rows, not estimated. A ⚠️ marks a column the source file does not contain.
| Field | Description | Filled |
|---|---|---|
receipt | The Division's receipt number — the unique key | 100.0 % |
permit | Permit number. NOT unique: one permit covers successive applications | 92.3 % |
status | Current status, verbatim | 100.0 % |
built | ⚠️ ⚠️ 1 where the status is Well Constructed — the answer a buyer needs first | 100.0 % |
expired | ⚠️ ⚠️ 1 where the permit lapsed without the well being built — 98,256 of them | 100.0 % |
county | ⚠️ County, case-normalised | 99.9 % |
aquifer | ⚠️ ⚠️ First named aquifer, split out of a delimited list | 96.9 % |
denver_basin | ⚠️ ⚠️ 1 where a named Denver Basin aquifer applies — a different legal regime | 100.0 % |
primary_use | ⚠️ ⚠️ First decreed use, split out of a delimited list | 100.0 % |
depth_ft | Well depth as reported | 63.4 % |
yield_gpm | Yield in gallons per minute as reported | 23.4 % |
static_water_level | Static water level, with its date | 48.6 % |
issued / expires / constructed / plugged | ⚠️ ⚠️ Four dates, normalised to ISO from mixed source formats | 99.0 % |
county_median_depth | ⚠️ ⚠️ The median depth of the county the permit sits in — computed here, published nowhere | 100.0 % |
The 8 fields marked ⚠️ do not exist in the source : we add them — a join, a normalisation, or a reconstructed history. That is the part a buyer cannot reproduce by downloading the official file.
⚠️ The source file’s applicant name is not in this dataset. It is not requested at download and not stored: these are largely rural homes, and nothing about the question this register answers requires a name.
⚠️ A blank in depth_ft is not a
zero. It means the Division was not told. Any aggregate built from
this file must exclude blanks rather than count them as noughts — and
should use a median, because a handful of holes go thousands of feet
down.
What it costs
- Change feed — USD 300 / monthOr USD 3 000 a year. At every collection, what came in, went out or changed since the previous one. This is the part that does not age.
- One slice — USD 90 / monthThe feed restricted to a single county, for those who do not need the rest.
- Full snapshot — USD 4 000, onceThe state of the register on the day of delivery, every field included. Listed last on purpose : a snapshot ages.
