Han River Water Level

This pulls real-time water level and flow rate data from the Han River Flood Control Office for specific observation stations in Korea. You ask by station name like "한강대교" or by station code, and it hits a proxy endpoint that handles the upstream API key for you. The proxy returns current water level in meters, flow rate in cubic meters per second, and relevant alert thresholds. If your query is too broad it'll give you a list of candidate stations to pick from. It's a straightforward wrapper around Korean government hydrological data, useful if you're building anything that needs to track Han River conditions without dealing with the HRFCO API directly.
