Our Mallows Bay buoy was recently removed for the winter. 
We will redeploy in the Spring of 2021. 

Thanks to the National Marine Sanctuary Foundation 
for funding the purchase of the buoy.

Late July Chesapeake Bay Hypoxia Report Available:

https://news.maryland.gov/dnr/2020/08/11/late-july-2020-hypoxia-report/

 

Due to approaching storm Isaias 

our continuous monitoring stations at

Public Landing-Coastal Bays; Hooper's Island, 

Seashore Beach and Point Lookout

have been temporarily removed to protect our equipment.

We will reinstall these sites as soon as the hazards have passed.

Monitoring Resumes!

Our biologists are back on water monitoring Maryland's water quality. Above is a map of continuous monitoring sites that have been deployed and have near or real-time data.

Tidal water quality data submissions have been completed for 2019.

Data status can be checked at:
http://eyesonthebay.dnr.maryland.gov/eyesonthebay/DataStatus.cfm

Official data available via the Chesapeake Bay Program Datahub:

http://data.chesapeakebay.net/WaterQuality

Due to the COVID-19 Pandemic, our field sampling operations were ceased on March 16, 2020 until further notice that it is safe for our staff to resume normal activities. 

The Eyes on the Bay website will continue to be active, and we continue to work on projects via telecommuting to improve the website, analyze data, and process datasets that were collected prior to the outbreak. As always, you can contact us at: eyesonthebay.dnr@maryland.gov.

BOOKMARK EYESONTHEBAY.NET

We have recently discovered that Eyes on the Bay is not appearing readily on popular search engines. Please bookmark our site, while we work to get this issued resolved.

September / End of Year Maryland Chesapeake Bay Hypoxia Report

Full details: https://news.maryland.gov/dnr/2019/10/03/september-hypoxia-report/

This is an animation of how salinity has changed in the Chesapeake Bay since the beginning of 2018, showing salinity decreasing as record rains and flows entered the Bay in latter 2018 and early 2019.

Inner Harbor Algal Bloom

This week our Inner Harbor National Aquarium sites saw algal blooms with a subsequent die-off, lowered dissolved oxygen and then a returning algal bloom.

We have a mobile friendly page where you can view current water quality conditions as text or gauges:

Monie Bay Site Real-time Data

The Monie Bay site on MD's Eastern Shore is posting real-time data. The site is part of the Chesapeake Bay-MD National Estuarine Research Reserve System. More on CBNERR and Monie Bay data.

Estuaries are dynamic places. Salinity around Maryland, like our monitoring site in the Wicomico River, is returning to normal after the heavy rainfalls from the past year have ceased.
