Hello Everyone,

Are any of you monitoring soft-bottom tidally-influenced streams? If so, I’d love to hear what protocols you are using and what you’re monitoring. I’m exploring the possibility of adding a few such sites to our monitoring program. I look forward to hearing your insights.

Joanna

Hi Joanna,

The Narrow River Preservation Association (http://www.narrowriver.org/templates/System/default.asp?id=40529) has been monitoring Narrow River here in RI as a part of URI Watershed Watch (URIWW) for many years. In brief, they monitor a dozen sites from the headwater stream (Gilbert Stuart*’s birthplace!) to the ocean biweekly for DO, temperature, salinity & filter water for subsequent lab analysis of chlorophyll and collect monthly water samples at low tide for URIWW lab analysis of bacteria (enterococci) , total, nitrate- and ammonia-N, total P. The monitoring protocol can be found online.  As a result of what they have found they are also monitoring several tributary streams and a storm drain outfall.

Interestingly Narrow River starts as the outflow of a freshwater lake, Carr or Pasacauco Pond, then becomes Gilbert Stuart stream and flows into 2 deep ponds, Upper and Lower Ponds, which are stratified due to chloride from salt and then into the Narrow (Pettasquamscutt) River. The ponds rarely destratify and when they do the river turns yellow from sulfur and reeks of hydrogen sulfide.

*Gilbert Stuart painted the famous portrait of George Washington that’s on our $1 bill.

Hope this is helpful,
