Results of CRC River Testing for 2013
CRC has completed its ninth year of river testing. The results are summarized in the accompanying graphs. More information about the CRC river testing program and detailed testing results can be found by clicking on the word “more” under Water Quality Monitoring on the upper right side of the page.
The unusually high rainfall early in the season kept the salinity very low for the months of June , July and August. Once the rain slowed the salinity started climbing and was at normal levels for the month of October.
The rains also kept the river very muddy. Of our 23 weekly data points, 12 set new 9 year lows for clarity. Even as the rain slowed the river had a difficult time recovering clarity and was below average for the entire year. The poor clarity and poor DO in September and October are unusual. If anyone has thoughts on what was happening there, let us know.
Except for short periods in early July and September, the DO level was consistently above the 5mg/l level considered adequate for aquatic life. During the high rains the Dissolved Oxygen (DO) levels were good and frequently above the average for the previous 8 years. This could be a result of the fresher water bringing oxygen into the system. As the rains diminished so did the DO levels. September and October had lower DO levels than in the heat of the summer. DO is related to temperature; hotter water can hold less oxygen, colder water can hold more oxygen. The last data point when the temperature was significantly lower was very good and probably reflects the colder water.

Corsica River Success Story
The Environmental Protection Agency is highlighting the Corsica River as a success story. Efforts to reduce pollution in two non-tidal tributaries show a significant decrease in nitrogen - showing that dedication, collaboration, and on-the-ground projects can make a difference. Read the full story here.
Our Maryland Grows Oysters (MGO) oysters were picked up from our growers along the River during the first two weeks of May. This is the fourth year that forty or more residents along the Corsica have grown oysters from spat on shell in cages hung from their docks starting in the Fall. Each Spring the oysters are deposited on an historic oyster reef we are restoring in the River. As in past years the work was done with the help of our Corsica River Conservancy (CRC) volunteers, Gunston School students and staff and Chesapeake Boatlift Services.
