Hydrology datasets

Streamflow, stage, and rating curves.

Open hydrology

Every rating curve, stage record, and snow course we touch is published under an open license. The data is the product; the map is just the front door.

The datasets

streamflow  15-min series, back to the 1970s
stage       raw heights plus rating curves
snow        SWE and depth, station + basin
climate     precip and temperature, gridded

Why it matters

Research, policy, and a farmer deciding when to irrigate all read the same numbers. Open data makes the basin legible to everyone.
