# USGS Water Data

> Use this tool when you need to access real-time and historical USGS water data, including stream flow, gauge height, and flooding conditions, to support applications such as hydrological data analysis, flood monitoring, and emergency management. It provides a modular API interface with separate modules for water services, real-time flood impacts, and geospatial queries, accepting location-based inputs and returning comprehensive water data outputs. Ideal for use cases requiring timely and accurate water data, such as environmental research and emergency response scenarios.

## Description

MCP server implementation by pgiffy that provides AI assistants with access to USGS (United States Geological Survey) water data through three complementary APIs: the Water Services API for real-time and historical water measurements like stream flow and gauge height, the Real-Time Flood Impacts API for current flooding conditions and reference points, and the OGC API for monitoring location metadata and geospatial queries. Built using Python with FastMCP and httpx, the implementation offers both a modular architecture with separate API modules and a consolidated single-file version, supporting comprehensive water data operations including site-specific queries, geographic filtering, flood monitoring, and agency/aquifer code lookups. Designed for applications requiring hydrological data analysis, flood monitoring systems, environmental research workflows, and emergency management scenarios where real-time water level and flooding information is critical for decision-making.
