August 9 2010 Dissolved Oxygen measurments

diana@southriverfederation.net — Fri, 13 Aug 2010 05:00:00 +0100

This week's bottom dissolved oxygen measurements indicate the expanding hypoxic zone from mid-river up to the Rt 50 bridge. Many of the tidal creek are also experiencing hypoxic conditions (2.0 mg/l or lower). This is due to the excessive nutrients causing the algae blooms, which then cause the low dissolved oxygen. Blue Crabs need above 3mg/l of dissolved oxygen to live, therefore at the moment the South River is not that hospitable for the blue crab. ---Diana

Building Moratorium in Mayo?

diana@southriverfederation.net — Thu, 20 May 2010 05:00:00 +0100

So much for a Building Moratorium on the Mayo Peninsula -My husband and I own two lots, one that has our house on it and the other is our "back yard", which is also mostly a wetland non-tidal marsh - that we like.We received this unsolicited letter from a realtor wanting to have us sell the second lot and build a house. Apparently she must know the "loop" holes. This type of behavior is unbelievable. I have attached the letter for all to see - feel free t [...]

Eyes Under the South River - Main stem water quality

diana@southriverfederation.net — Wed, 19 May 2010 05:00:00 +0100

The following is our own "Eyes Under the South River". This comes from my weekly water quality monitoring program, therefore this is REAL data and not a model. The graphs and interpretations are performed by Andrew Muller, PhD USNA-Oceanography and Diana Muller, South RIVERKEERER.

The Chesapeake Bay Restoration Strategy is now out as presented by Lisa Jackson (EPA administrator) yesterday. She stated that only thing needed is money and resources.

I would like to include Three more things:

1) The absolute old fashion American CAN DO. With [...]

No regulations on Snapping Turtle trapping

diana@southriverfederation.net — Wed, 05 May 2010 05:00:00 +0100

In the State of Maryland there are no regulations on size or limit on the catch of Snapping Turtles. Today I received a call about a trapper in Big Pond, Mayo Peninsula - the trapper had about 10 pots and was filling his John boat with as many Snappers as he could, I could not believe what I was witnessing. We need to get regulations on Snapping Turtles before another species starts to disappear. The growth rate on these reptiles is extremely slow, and trapping them until th [...]

2010 Snapshot, Total Nitrogen

diana@southriverfederation.net — Tue, 04 May 2010 05:00:00 +0100

Below is the GIS plot of the samples taken for total nitrogen for the Snapshot. No surprise that Church Creek had the highest concentration, considering that this sub-watershed is 60% impervious. The Chesapeake Bay program threshold for Total Nitrogen is 0.65mg/l, therefore the orange and red area were elevated. --Diana

2010 South River Snapshot, Bacteria

diana@southriverfederation.net — Tue, 04 May 2010 05:00:00 +0100

I have finally completed the data analysis for the 2010 South River Snapshot. I want to thank all of the volunteers for coming out Saturday morning (April 22, 2010) to sample the South River Watershed. Below is the bacteria data - Enterococci. The threshold is 104 colony forming units per 100 milliliter. Only two sites exceeded that threshold and both are explainable. The one site is near the Davidsonville Wildlife Sanctuary, which is being re-designed this fall. [...]

South River Hypoxic Zone

diana@southriverfederation.net — Mon, 22 Feb 2010 05:00:00 +0100

The X,Y,Z plot below was developed using the monitoring data that I collected, and was compiled by Dr. Muller at the United States Naval Academy. This plot is for July and indicates both a hypoxic (in dark red) and an anoxic (in black) zone from Liberty Marina toward the Rt 50 Bridge. Hypoxic conditions are 2.0 mg/l or less and anoxic are 0.2mg/l or less. This is one indicator used in the South River Scorecard for the River's health.--diana
