Nibi Metrics is a water intelligence platform built and run by Muskoka Research Inc., an independent Canadian company. "Nibi" means water in Anishinaabemowin. The platform tracks water levels, flow, weather, and forecasts for more than 19,410 gauged lakes and rivers in a growing number of countries, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, the Environment Agency for England, the Scottish Environment Protection Agency, Natural Resources Wales, the Office of Public Works in Ireland (waterlevel.ie), the Norwegian Water Resources and Energy Directorate (NVE), the State of Queensland's, the State of Victoria's, the State of South Australia's, the Northern Territory's and the State of Western Australia's water monitoring networks, the French State's hydrometric network (Vigicrues, through Hub'Eau), the German Federal Waterways and Shipping Administration's gauges (WSV, through PEGELONLINE), and on the Great Lakes the Canadian Hydrographic Service and NOAA.
Nibi began at a family cottage on Lake Muskoka, Ontario, where the spring freshet floods the shoreline in most years and the only way to know what the water was doing was to stand on the dock and look. The platform grew from one question - how high will it get this time - into a continental system that answers it for any monitored lake or river: what the level is right now, how it compares to what is typical for this exact date, which way it is moving and how fast, and what the next days are likely to bring.
Every number on the platform is measured, not modelled - read from government gauges and compared against that location's own historical record. Nibi is built by one person, funded by its members, and carries no outside investment.
