Abstract
This resource contains individual (discrete) field discharge measurements collected across all five Quantifying Ecosystem exports across Space and Time (QuEST) project watersheds: Brush Creek, Arkansas (BR); Dog Valley, Nevada (DV); Santa Fe River, New Mexico (NM); South Sandy, Alabama (SS); and Lamprey River, New Hampshire (LMP). Measurements were made by one of two methods — salt slug (dilution gauging) or velocity-area (flow meter) — with the method used depending on site and watershed (South Sandy and the site DVMS1 in Dog Valley use velocity-area exclusively; Santa Fe River uses salt slug exclusively; Brush Creek and Lamprey River use a mix of both, depending on the visit; the rest of Dog Valley uses salt slug).
This resource includes every site that was ever visited for a discharge measurement. Of the 73 sites represented here, 27 currently have a companion continuous-discharge product published in the "Continuous Streamflow Records" resource; measurements at the remaining sites were made at locations without a PT installation, or at PT sites whose rating curve has not yet been finalized for publication. Each row is flagged with a `used_in_rating_curve` column accordingly, so this resource serves both as a standalone record of field discharge measurements and as the supporting data behind the rating curves in the companion continuous-discharge resource.
Measurements span May 2024 through October 2026, totaling 1,322 individual discharge measurements across 73 sites (as of August 31st 2026).

What's in this resource
Discrete field discharge measurements (Q, m³/s) collected across all five QuEST project sites: Brush Creek, Arkansas (BR); Dog Valley, Nevada (DV); Santa Fe River, New Mexico (NM); South Sandy, Alabama (SS); and Lamprey River, New Hampshire (LMP). This is every site ever visited for a discharge measurement.
File naming
<Watershed>_individual_discharge_measurements_full.csv — that watershed's entire period of record.
<Watershed>_individual_discharge_measurements_WY####.csv — one USGS water year only.
ALL_individual_discharge_measurements_full.csv — all five watersheds combined.
Water year convention
USGS standard: October 1 – September 30, labeled by the ending calendar year (e.g. Oct 1, 2024 – Sep 30, 2025 = WY2025).
Columns
| Column | Meaning |
|---|---|
Watershed |
Two/three-letter watershed code: BR, DV, NM, SS, LMP |
DataID |
Site identifier |
DateTime |
Timestamp of the measurement (local time) |
Method |
How discharge was measured: Salt slug (dilution gauging) or Velocity-area (flow meter) |
Q_m3s |
Discharge in cubic meters per second |
Stream_State |
Channel condition at the time of measurement: Continuous flow, Dry, Pooled, Flow/Pool, or blank if not recorded |
used_in_rating_curve |
TRUE if this site currently has a published continuous-discharge product (in the companion resource) that this measurement helped calibrate; FALSE if the site has no PT, or its rating curve hasn't been finalized yet |
qc_flag |
Field/lab data-quality flag: Bad or OK, or blank if not flagged |
notes |
Free-text field/lab notes, where available. Populated for Dog Valley, Santa Fe River, and Lamprey River (their field forms carry a notes field); blank for Brush Creek and South Sandy, whose source sheets don't have an equivalent column |
Method by watershed
| Watershed | Method | Time Zone |
|---|---|---|
| South Sandy (SS) | Velocity-area, all sites | Central Time |
| Santa Fe River (NM) | Salt slug, all sites | Mountain Time |
| Dog Valley (DV) | Salt slug, all sites except DVMS1, which is velocity-area | Pacific Time |
| Brush Creek (BR) | Mix of both, depending on the visit | Central Time |
| Lamprey River (LMP) | Mix of both, depending on the visit | Eastern Time |
Sites and rating-curve linkage
This resource includes 75 sites; 21 of them currently have a companion continuous-discharge product in the "Continuous Streamflow (Discharge) Records" resource (used_in_rating_curve = TRUE). The remaining sites were either never instrumented with a PT, or their rating curve hasn't been finalized for publication yet. See metadata_individual_discharge_measurements.csv for the exact site-by-site breakdown (measurement count, date range, and rating-curve status per site).
Related data
The continuous, PT-derived discharge time series these measurements helped calibrate is published separately — see the "Continuous Streamflow (Discharge) Records" resource, linked from this project's Collection page.
