Ohio: Water quality monitoring network

Funds for the load monitoring stations are from federal, state, and local governments, as well as private enterprises. In 2018 monitoring partners brought four new stations online. Annually, between 100-500 water quality samples are collected at every site. The timing of which samples are collected is strategic to allow for the calculation of continuous nutrient loads. These loading data allow for a better understanding of each tributary’s contribution to nutrient delivery to Lake Erie. They are also used to track changes in nutrient delivery based on land use changes/best management practices adoption.
