US flood risk and stream gauge APIs
Combine FEMA mapped hazard, observed discharge and river forecast context for US screening. Compare listed sources, access requirements and evidence for us flood risk and stream gauge apis.
3 sources · For environmental scientists, flood consultants, GIS analysts, hydrologists, water quality specialists. Enrichment describes potential applications; review source evidence and limitations.
Forecasts and observed gauge levels do not revise regulatory flood zones or establish parcel safety.

USGS Water Data API ↗
USGS water observations and monitoring-location metadata through modern water-data APIs.
What's in it
- Data offered docs-verified
- continuous sensor measurements · daily values · time series metadata · monitoring-location metadata · water quality samples · discrete water-quality data (Water Quality Portal) · gaging-station imagery (NIMS) · daily, monthly and annual statistics
- Coverage llm-inferred
- United States
- Formats docs-verified
- OGC API · STAC
- Access docs-verified
- Free to use; API key optional for higher rate limits. Licence not stated.
Useful for
- Use cases llm-inferred
- Baseline river flow and gauge record review for FRA inputs from nearest USGS gauge (US sites only) · Flood event analysis from continuous sensor records at gauged catchments · Water quality baseline sampling review for environmental assessment (US sites only) · Gauge camera imagery for site visit verification and condition checks
- Audience llm-inferred
- flood consultants · hydrologists · GIS analysts · environmental scientists · water quality specialists
Limitations
- Constraints llm-inferred
- Covers United States monitoring locations only; not applicable to UK sites · Rate limits apply without an API key · Licence not specified in catalogue metadata · Multiple API families (OGC, STAC, legacy Water Services, NIMS) may require different query patterns · NIMS imagery requires constructing full image URLs from camera base paths and returned filenames

Frequently asked questions
Which listed sources support US flood risk and stream gauge APIs?
Start with FEMA National Flood Hazard Layer, USGS Water Data API, NOAA National Water Model / NWPS. Combine FEMA mapped hazard, observed discharge and river forecast context for US screening.
What should I check before using these sources for us flood risk and stream gauge apis?
Forecasts and observed gauge levels do not revise regulatory flood zones or establish parcel safety.
How do I inspect FEMA National Flood Hazard Layer through MCP?
Connect an MCP client to https://terramcp.earth/mcp and call get_source with slug fema-national-flood-hazard-layer. Review its provenance, access requirements and limitations before contacting the upstream service. Discovery does not make every listed source directly executable through the router.
Are these sources free and independently verified?
Access and licence terms belong to each upstream provider; some products require registration or payment. Open each listing for evidence, health status and enrichment provenance. A wrapper and its underlying API can refer to the same dataset and are not independent observations.
