This is the complete record for Carneros Creek as one CSV file, rebuilt by the publisher on every build. The archive copy of the same readings may be split into yearly segments; this file is not a link to a segment and always has the same name.

What is in the file

One row per reading, plus a header row that is always there: UTF-8 without a byte-order mark, LF line endings, and RFC 4180 quoting, so a field is quoted only when it holds a comma, a quote, or a line break. Rows are in a fixed order — gage, then measurement, then time — which is what lets two versions of the file be compared line by line to find what changed. Values are the exact numbers the site stores, not rounded for display; the unit each one is in travels with it in the row, in unit_metric, unit_imperial, and raw_unit. Both observed_at_utc and ingested_at_utc are ISO-8601 in UTC with a trailing Z and whole seconds, so a timestamp is never ambiguous across the daylight-saving change; the local times in the table above are those same instants read in the gage's time zone.

stream_slug: Which stream the reading belongs to. Every row of this file is the same stream.
gage_slug: Which gage on that stream took it — a stream can have more than one.
logger_sn: The data logger's serial number, recorded with the reading and never rewritten.
sensor_sn: The sensor's serial number, so swapping a sensor later cannot move an old reading's provenance.
measurement_type: What was measured, as a code — the same codes this page labels in its own column headings.
observed_at_utc: When the reading was taken, as ISO-8601 UTC with a trailing Z, whole seconds: 2026-09-14T21:45:00Z.
value_metric: The value in metric units, exactly as the site stores it.
unit_metric: The unit value_metric is in, written in each row beside it.
value_imperial: The same value in US units, converted with the unit registry's factor and rounded to its precision plus two places.
unit_imperial: The unit value_imperial is in.
raw_value: The value as the logger reported it, before any conversion.
raw_unit: The unit raw_value is in, as the logger reported it.
source: Which ingest path produced the row, so a change of instrument is visible in the data.
ingested_at_utc: When the site stored the reading, in ISO-8601 UTC with a trailing Z — when it arrived, not when it was measured.

About this data

Water level at gage: depth of water above the sensor, relative to the level recorded when the logger was installed. It is not a surveyed river stage and can't be compared between gages.

7-day average daily high temperature (7DADM): the mean of the daily maximum water temperature over seven consecutive local days, calculated only when all seven days are complete. The steelhead bands below are applied to that value, never to a single reading.

All times shown are gage-local time (America/Los_Angeles), the same zone the site is configured for; data files carry UTC timestamps.

Steelhead water-temperature bands, applied to the 7-day average daily high.
Band	7-day average daily high	What it means
Good	at or below 60.8 °F	Good for young steelhead
Stressful	above 60.8 °F and below 71.6 °F	Stressful: slower growth, more disease
Dangerous	at or above 71.6 °F	Dangerous: can kill steelhead
Federal reference	68.0 °F	Federal recovery-plan limit for suitable summer rearing.
Heat spike	75.2 °F	A single reading or daily high at or above this value.

Biological thresholds from published research (EPA 2003 and others), not legal limits. Sources: EPA Region 10 (2003) Tables 1, 3, and 4; NMFS 2016 recovery plan, Vol. IV; WDOE 2002 via Carter 2005; Nielsen et al. 1994; Sullivan et al. 2000.

Thresholds are pending scientific review.

Seasonal limits for spawning and smoltification are configured but not applied.

Measurements come from LI-COR Cloud loggers and configured CDEC stations, published by Water Audit California.
