The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_daily_values Daily USGS Streamflow Statistics (Current or Historic) ~278
Daily statistics (default: mean) for one or more USGS gauges. Use this for any query that crosses days or asks about historic dates. Pass either `period` (relative-to-now) OR `start_date`/`end_date` (historic range), not both. For real-time sub-hour resolution prefer `get_instantaneous_values`. Returns one daily value per (site × parameter × statistic × day). USGS quality codes: 'A' = approved, 'P' = provisional.
| Name | Type | Req | Description |
|---|---|---|---|
| end_date | – | – | Historic range end (YYYY-MM-DD). Defaults to today when start_date is set. |
| parameter_codes | array | – | 5-digit parameter codes. Defaults to ['00060'] (discharge mean). |
| period | string | – | Relative window ending now. Examples: 'P7D', 'P30D', 'P1Y'. Mutually exclusive with start_date/end_date. |
| sites | array | yes | Array of USGS site numbers. Single-site queries are typical. |
| start_date | string | – | Historic range start (YYYY-MM-DD). Pair with end_date for an explicit window. |
| statistic_codes | array | – | USGS statistic codes, '00003' = mean (default), '00001' = max, '00002' = min, '00008' = median. |

get_instantaneous_values Real-Time USGS Streamflow / Gage Height ~241
Real-time readings (typically 15-minute cadence) from a USGS gauge. Returns one or more time series, by default discharge (00060, ft³/s) and gage height (00065, ft), over a relative period ending now. Use this to answer 'what is the river doing right now?'. USGS rejects historic dates on this endpoint; for past data use `get_daily_values` with start_date/end_date instead. For a 'what gauges exist near here?' first-step query use `search_sites`.
| Name | Type | Req | Description |
|---|---|---|---|
| parameter_codes | array | – | Specific 5-digit parameter codes to retrieve. Defaults to ['00060', '00065'] (discharge + gage height). Pass ['00010'] for water temperature, etc. |
| period | string | – | Relative time window ending now. Default 'PT2H' (past 2 hours, returns ~8 readings at 15-minute cadence). 'P1D' returns ~96 readings. |
| sites | array | yes | Array of USGS site numbers to fetch in one call. Most queries pass a single site, but the API supports batched fetches. |
No output schema declared.
No examples provided.
get_site_info USGS Gauge Site Metadata ~150
Returns metadata for a single USGS gauging station: official name, coordinates, site type (stream/lake/groundwater/etc.), hydrologic unit (HUC), state/county codes, and gauge altitude. Use after `search_sites` finds candidate gauges, or to confirm a site number returned in someone's data.
| Name | Type | Req | Description |
|---|---|---|---|
| site_number | string | yes | USGS site number, 8 to 15 digits identifying a single gauging station. Examples: '12045500' (Elwha River at McDonald Bridge near Port Angeles, WA); '12048000' (Dungeness River near Sequim, WA). Use `… |

search_sites Find USGS Gauge Sites Near a Location ~334
Find active USGS stream-gauge sites by either (a) latitude/longitude/radius_km, or (b) US state postal code. Returns site numbers, names, coordinates, HUC, and altitude, feed the resulting site numbers into `get_instantaneous_values` or `get_daily_values`. Defaults filter to surface-water streams (siteType=ST) with real-time data (hasDataTypeCd=iv); pass site_type/has_data_type to override. Pass either lat+lng+radius_km OR state_code; the lat/lng path is preferred for place-aware queries.
| Name | Type | Req | Description |
|---|---|---|---|
| has_data_type | string | – | Restrict to sites that publish the given data type: 'iv' = instantaneous (real-time, default), 'dv' = daily values, 'qw' = water quality, 'gw' = groundwater levels. |
| lat | number | – | Latitude of the search center. Required if state_code is not provided. |
| lng | number | – | Longitude of the search center. Required if state_code is not provided. |
| radius_km | number | – | Search radius in km around (lat, lng). Default 25. |
| site_type | string | – | USGS site type code: 'ST' = stream (default), 'LK' = lake, 'GW' = groundwater, 'AT' = atmosphere, 'ES' = estuary. Full list: https://help.waterdata.usgs.gov/site_tp_cd |
| state_code | string | – | US two-letter state code. Mutually exclusive with lat/lng. Returns ALL active stream gauges in the state. |
