Did you know scientists have been routinely measuring streamflows within Yellowstone since the 1880's? Streamflow (discharge) is the volume of water that moves past a reference point over a period of time. This data helps answer management questions related to water availability, water quality, ecological conditions, infrastructure design and maintenance, hazards, climate change, and water rights. It also lets visitors know when it’s time to pull out their fishing rod and waders each year.
