Watershed report cards are powerful tools to describe ecosystem status, increase public awareness, and inform and influence decision makers to improve the health of a watershed. This is the first Upper Rio Grande Report Card. It is the collective effort of dozens of stakeholders throughout the Upper Rio Grande watershed. Indicators in the report card were selected to assess the health of four different values in the watershed:

1 September 2022

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.

13 October 2021

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2019-2020 Coastal Bays health. Coastal Bays health is defined as the progress of four water quality indicators (total nitrogen, total phosphorus, chlorophyll a, dissolved oxygen) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals.

2020 Severn River Report Card

Nathan Miller, Alexandra Fries ·
1 September 2021

Published in 2021, the 2020 Severn River Report Card summarizes data collected in the summer of 2020. The Severn River received a C- grade in 2020. All three indicators--water clarity, dissolved oxygen, and underwater grasses--declined from 2019 to 2020. However, more samples were collected in 2020 than in 2019, so comparing the two years is not apples to apples.

Pacific and Atlantic data from 2012–2018 indicate that U.S. coral reefs are in fair condition. Most themes did not meet their historical references, meaning they are moderately to very impacted. There are exceptions, but overall, the data suggest that reefs are vulnerable to further decline due to threats from ocean warming and acidification, coral disease, and fishing impacts. Download the document to learn more about U.S. Coral Reef condition.
