Index-Velocity Technical Tips
Quick Sheets
The USGS has prepared technical quick sheets to supplement the more formal index-velocity guidance publications. The provided index-velocity quick sheets are a great resource for hydrographers of all experience levels.- Site Selection and Reconnaissance Tips (pdf)
- Index-velocity Rating Tips (pdf)
- Acoustic Doppler Velocity Meter Cell Size (pdf)
- Stage-area Rating Tips (pdf)

Real-time Index Velocity Examples
It may also be beneficial to view real-time data from operational index-velocity stations. The following links provide examples of USGS streamflow-gaging stations with real-time, online data produced from index-velocity instrument and methods:
Columbia River at the Dalles, Oregon (14105700) - long-term AVM index-velocity site
