Stream-Watch is Coming Soon!

By Alan Samel

The annual DCVA Stream Watch will be April 15th.  It’s hard to believe that we have been doing this for over 15 years!  This is a tribute to the legions of volunteers that have helped in the past and continue to help.  If you have never participated in the Stream Watch there’s no better time than now.  Like the Vernal Equinox, the Stream Watch occurs once a year.  And now is the time for you to get involved.  The Stream Watch is one way for us to give back to our communities in our continuing and non\-stop effort to enhance the Darby Creek Watershed.

Over the years we have experienced glorious and, um, less than glorious days.  Last year we had a beautiful spring day!  The sun was shining, the birds were singing, and we were right where we wanted to be: in the streams!  This year, we’re hoping for another incredibly beautiful day…hope springs eternal.  It’s always easier to get into the stream on a beautiful day; but this is a rain or shine event and the show must go on.  We plan to start at 9:00 and hope to finish around 3:00.  People come to all sites and people help out at some sites.  Anyone with an interest can come when they can.

This is a great opportunity for you to get in the creek, take samples, work with the samplers, and see what is living in Darby Creek.  We take samples from five locations on Darby Creek: Bartram Park in Darby, Darby Creek Road in Havertown (downstream from the Haverford Reserve), Skunk Hollow in Radnor, the Brandywine Preserve at Waterloo Mills in Easttown, and the Swedish Cabin in Upper Darby.  What a great way to meet others and learn more about Darby Creek!! 

The insects and bugs we collect provide a snapshot of the health of Darby Creek.  This is the ninth year of intense sample collections and identifications.  From this long-term sampling, a trend of the stream health at each site has been determined.  Each year we compare our findings from the water quality determinations from the previous years.  It’s a way of getting the big picture from a lot of very small bugs!  But getting into the stream and collecting the bugs is only part of the stream watch program. 

The next step will be to identify the bugs pulled from the stream.  We then can identify the level of water quality for that section of the creek.  The Insect Identification Workshop will be scheduled for this coming fall.  Please check the DCVA web-site for more information as we get closer to this time.

2016 Stream-Watch a Huge Success!

Alan Samel

The annual DCVA Stream Watch was April 16th.  It’s hard to believe that we have been doing this for almost 15 years!  This is a tribute to the legions of volunteers that have helped in the past and continue to help.  If you have never participated in the Stream Watch there’s no better time than now.  Like the Vernal Equinox, the Stream Watch occurs once a year.  And now is the time for you to get involved.  The Stream Watch is a great way for us to give back to our communities in our continuing and non-stop effort to enhance the Darby Creek Watershed.

Over the years we have experienced glorious and, uhm, less than glorious days.  This year we had glorious conditions!  It was a beautiful, sunny day that hovered in the mid-50s the entire day. 

This is always a great opportunity for us to get in the creek, take samples, work with the samplers, and see what is living in Darby Creek.  On this day, we took samples from five locations on Darby Creek: Bartram Park in Darby, Darby Creek Road in Havertown (downstream from the Haverford Reserve), Skunk Hollow in Radnor, the Brandywine Preserve at Waterloo Mills in Easttown, and the Swedish Cabin in Upper Darby.  What a great way to meet others and learn more about Darby Creek!! 

The insects and bugs we collect will provide a snapshot of the health of Darby Creek.  We have been doing this for almost 15 years!  From this long-term sampling, a trend of the stream health at each site has been determined.  Each year we gather data and compare our water quality findings from previous years.  It’s a way of getting the big picture from a lot of very small bugs!  But getting into the stream and collecting the bugs is only part of the stream watch program. 

The next step will be to identify the bugs pulled from the stream.  We then can identify the level of water quality for that section of the creek.  The Insect Identification Workshop will be scheduled for this coming early 2017.  Please check the DCVA web-site for more information as we get closer to this time.

The DCVA ("StreamWatch") is a yearly study of water quality in the Darby Creek watershed. While it is possible to measure water quality and water pollution, the animals in the creeks have much to tell us about water quality – they spend their entire lives in the creek. In the "Streamwatch" macroinvertebrates (animals without backbones that are macro- large enough to see with the naked eye) are collected. These organisms have all been labeled as pollution tolerant, pollution sensitive, or facultative- meaning they can live in healthy or in impaired (polluted) environments. The collections are done in the spring at a variety of locations throughout the watershed. The same spots are checked every year so that we can watch the quality of the water in the creeks over time. In the autumn we identify the organisms and calculate a "biotic index" a mathematical measure of stream health based on the proportions of pollution tolerant, pollution sensitive, and facultative types of organisms at the study sites.

We welcome volunteers who wish to learn the stream side and the laboratory techniques! In addition, we are meeting with local residents, schools, scout troops, etc. to encourage the groups to adopt sections of the stream for monitoring. DCVA is also working with interested groups to provide the required training, equipment and technical support to monitor the sites.

This is a great opportunity for you to get in the creek, take samples, work with the samplers, and see what is living in Darby Creek.  We take samples from five locations on Darby Creek: Bartram Park in Darby, Darby Creek Road in Havertown (downstream from the Haverford Reserve), Skunk Hollow in Radnor, the Brandywine Preserve at Waterloo Mills in Easttown, and the Swedish Cabin in Upper Darby.  What a great way to meet others and learn more about Darby Creek!!
