cyanheads/usgs-water-mcp-server

Gates and workflows for the water_* tools over USGS stream gages and groundwater wells. Covers whether a river or aquifer is high or low right now, telling live gages from discontinued ones, reading depth-to-water rankings (they run inverted), finding the parameter code a site actually reports, time zones and data lag, and SQL over staged series. Use when answering questions about USGS streamflow, gage height, groundwater levels, or water-quality sensors.
