Water observation histories
A weekly history for a lake or reservoir you name is planned. It is not available. The open monthly series is on the Western Terminal Lakes page.
Open lakes dataset Plans and prices
The weekly lake watch is planned. Licensed products are by quote.
Who it is for
Water managers, irrigation districts, utilities, and researchers who track many water bodies across several agencies' records.
What you get
The same pipeline as our open Western Terminal Lakes dataset, applied to your list of sites and joined to the gauge and reservoir records that describe them. The open release stays free; the paid part is your site list, the joins, the cadence, and support.
- What you get
- One consistent history per eligible lake or reservoir: surface extent, plus level, reported storage and flow where a gauge publishes them, with units and datums reconciled and a quality flag on every value
- Coverage
- Western United States first; satellite extent where our open lake pipeline covers the water body
- Cadence
- Planned. The free open dataset is 19 series on 18 lakes, by month. Great Salt Lake is split into a north arm and a south arm.
- Delivery
- CSV, Parquet, API

Other lakes and reservoirs
- What we can add
- Any lake or reservoir that satellites can see clearly, generally open water larger than about 10 hectares. We check smaller ones before quoting. Before purchase we confirm, for each site, which variables are available, how far back they go, how often clear satellite views arrive, and their quality limits. Weekly processing does not guarantee a new clear view every week.
- What each history includes
- Satellite water area from Sentinel-2 imagery wherever the water body is visible, plus level, reported storage and flow from public gauge and reservoir records wherever those exist. Where no gauge exists, the history is satellite area only, and it says so.
- Choosing your sites
- One lake or reservoir, or a bundle of up to 25. Weekly monitoring is planned. When it opens, you pick them in the customer app from the list above, by search or by drawing a boundary. For a water body that isn't listed, use the form below.
- New sites
- A water body we haven't monitored before is added to your plan with its full history back to 2019.

Works with ArcGIS and your other tools
| Tool | How the data arrives | Status |
|---|---|---|
| Spreadsheets | CSV with one row per site per week: level, surface area, storage and flow where they exist, each with its unit, source and quality flag | Planned |
| ArcGIS and QGIS | Site locations and water outlines as GeoPackage or GeoJSON, joined to the CSV by site ID | Planned |
| Python and R | Parquet with the same columns as the CSV | Planned |
| Your own software | JSON time series through the API | Planned |
