USGS - Harvey Gaged Streamflow Timeseries

This resource provides datasets for stream discharge (flow rate) in cubic feet per second, and gage height (stream depth) from 924 active USGS gages in the Hurricane Harvey impact zone across Texas, Louisiana, Mississippi and Arkansas (see shapefile for all gages).

These data were obtained from the USGS National Water Information System (NWIS) [1] using R scripts provided here. When running these R scripts, 745 of the 924 gages had gage height values, and 577 of the 924 had discharge values. For help in using these R scripts, USGS used to provide support tools but the links for those no longer work. I used R Studio on Windows for these retrievals.

Formats provided:
- Shapefile and csv for gage locations, including link to USGS gage details [1]
- Tabular (csv) datasets for timeseries of water discharge (flow rate) in cubic ft/sec, and timeseries of gage height in ft.
- R scripts to download timeseries data from NWIS
