2021 Severn River Report Card

Abstract

Published in 2022, the 2021 Severn River Report Card summarizes data collected in the summer of 2021. It was a troubling year for water quality in the Severn River in 2021. The overall grade for the Severn River dropped to a D+ in 2021, largely due to a decline in underwater grasses. This decline offset improvements seen in dissolved oxygen.
