Stormwater runoff from nonpoint source pollution is one of the most significant threats to aquatic ecosystems in the United States. Pollutants such as motor oil leaked on parking lots, plastic grocery bags, pesticides, fertilizers, detergents, and sediments are known as nonpoint source pollutants. Direct contamination of waterways, such as industrial waste pouring from a factory drain into a river, is an example of point source pollution. Scientists and environmental managers break pollution into two categories: point source and nonpoint source pollution. Fishermen, whitewater paddlers, others who use water recreationally use these river predictions to plan safe outings. Hydroelectric dam operators use similar information to produce electricity efficiently. Cargo ship and barge captains on large rivers use information on the current and forecasted river level, and flow rate for navigation. These decisions can reduce flooding threats, limit the impact of droughts, and influence fish migrations. ![]() Water managers use this information to make decisions about water allocation, such as how much water should be released from a reservoir during spring runoff. Hydrologists (water-system scientists) use snow data, river gauges, evaporation rates, precipitation forecasts, radar, and other data to produce forecasts that allow water managers and others to plan efficient and safe use of this natural resource.
