Steps

  1. Identify the USACE office (district) and location ID for the gauge/lock/dam of interest.
  2. Call the public CWMS Data API's timeseries resource for a flow, discharge, or precipitation parameter at that location.
  3. Set the date/time range and units for the query.
  4. Read the returned flow/discharge values to assess current conditions (e.g., high-flow conditions that could affect approach safety).
  5. Combine with lock status/queue data (see the Corps Locks route) for a fuller navigation-safety picture.
