current_conditions ~264 tokens
Latest instantaneous (real-time) readings for one or more USGS gauge sites. Returns the most recent value per site × parameter — e.g. current streamflow and gage height for a river. Common parameter codes: 00060 = discharge/streamflow (ft³/s), 00065 = gage height (ft), 00010 = water temperature (°C)
daily_values ~328 tokens
Daily-values time series for a single USGS site + parameter over a date range. Returns one statistic per day (default mean). Useful for trends, hydrographs, and historical comparison. Common statCd: 00003 = mean, 00001 = max, 00002 = min. Common parameter codes: 00060 = discharge (ft³/s), 00065 = ga
find_sites ~210 tokens
Discover active USGS gauge sites in a US state that are currently reporting a given parameter (real-time). Returns sites with their latest reading; useful for finding which gauges are live in a region. Can match many sites, so results are capped. Keyless.
