Northern Water’s weather network began in 1986 to provide high quality data for use in irrigation scheduling. While many other uses for the network have changed throughout time, one of the primary products is reference evapotranspiration calculations for use in irrigation scheduling. Evapotranspiration (ET) is a combination of transpiration, which is plant water loss through the leaves, and soil evaporation.
Northern Water’s weather network currently consists of 21 weather stations. Nineteen are located on the Front Range and eastern portion of our boundaries, while the other two are on the West Slope.
