Check out our data on Riverkeeper’s site

Every month, SKWC citizen scientists go out and collect samples from 14 different locations along the Saw Kill. They record observations and data such as temperature and salinity. The samples are then taken to the Bard Water Lab, where they are processed for parameters such as sewage indicating bacteria, nutrients, and turbidity.

But what happens to that data? We present lots of our findings at our monthly community meetings. And now, thanks to Riverkeeper, you can view our findings on Enterococcus counts online. Their interactive map shows our sampling locations, and data alongside environmental conditions such as rain events.

Entero what? Enterococcus is a bacteria found in the intestines of humans and other warm blooded animals. It’s called “fecal indicating” because of its presence in human sewage. Therefore, an abundance of enterococcus in the water can correlate with sewage contamination. The EPA uses enterococcus counts to regulate water safety. Riverkeeper shows these counts alongside rainfall data as rain events often trigger fecal contamination. Looking at the two side by side helps us understand whether enterococcus levels are weather related or due to other factors.

Take a look around the site! They have lots of interesting information on water quality, as well as data on surrounding watersheds. The map reminds us of our watershed’s connection to surrounding watersheds and communities. It’s exciting to see our separate data collections coming together to create a larger, more complex picture.

Electrofishing below the Annandale Dam

On Tuesday, two Saw Kill interns and a Bard student Office of Sustainability intern went electrofishing with the DEC. We donned our waders, with nets in hand, to look at what kind of fish diversity exists below the Annandale Dam.saw kill electrofish 1

The way electrofishing works is by a handheld probe in the water that delivers a small electrical current. This shocks the fish for about 5 seconds, allowing enough time for a net to scoop them up in to a bucket. The DEC is interested in looking at what kind of biodiversity exists in the Saw Kill, but were also particularly interested in the eel population. The dams and waterfalls along the Saw Kill make eel migration tough, but they still manage to make it, proved by the large eel we found close to the dam.

 

Along with the american eel, we found a mixture of native and non native fish such as a brown trout, white sucker, largemouth bass, cutlips, bluegill, rock bass, spiny cheak crawfish,redfin pickerals, black nosed dace, yellow bullhead, and tessellated darters. I had never seen most of the above mentioned fish before, and it was exciting to learn about them and see how diverse the Saw Kill is. Thanks to the DEC for including us in  a great afternoon!

 

Community walk along the Saw Kill

Last week we had an awesome walk along the portion of the Saw Kill that runs through Bard campus with ecologist Gretchen Stevens from Hudsonia. It was a beautiful summer night, and a great opportunity to catch up with old friends, and meet some new faces. It was wonderful to see families, students, folks from different Hudson Valley environmental groups, and community members from Red Hook and Milan all out together.

Our conversation, as we stopped at different points along the Saw Kill, focused on the ecology of the river and the much discussed micro-hydro project. Gretchen confirmed what we all know to be true, that our Saw Kill is a unique and special environment. It happens to be home to unique bird species such as the migrating Louisiana Waterthrush, and the Winter Wren. We also looked at rare plant species like the American Spikenard. We talked about the trout species, such as brown trout, that make their home in the Saw Kill. This ties into recent conversations on stream classification as the Saw Kill is designated class T for trout, as well as class B. And my favorite Hudson Estuary fish, the American Eel, got a special mention as we took a look at the eel bucket/ladder system on one of the existing dams.

Many questions on the feasibility of a micro-hydro project, and consequences of such a project or dam removal were discussed. A group, that presented to the SKWC in February, has been putting together information on the possibility of micro hydro on one of the old dams along the Saw Kill. For the minutes of that meeting see here. This is an ongoing community conversation that is addressing questions surrounding habitat, migration, eel accessibility, sediment loading, flow, etc. in order to understand the effects of such a project.

Along with all of the information gained, it was a wonderful opportunity to not just talk about the Saw Kill but experience the Saw Kill as a community.

We look forward to seeing everyone again at our next meeting, Wednesday, August 16th.

Summertime along the Saw Kill

Our water monitoring program is year round, and in full swing this summer. If you haven’t gotten the chance to get up close to the Saw Kill with fellow community volunteers to collect samples and record observations, this summer is a great chance!

We are lucky our watershed is located in the beautiful Hudson Valley. Volunteer snapshots show off what a beautiful waterway we have, and why we’re so determined to protect it. Get out in the sunshine and in to your water way by becoming a volunteer in the water monitoring program. Our next sampling day is Friday, August 11th and we would love to see you there!

Taking our community meeting to the Saw Kill

We hope everyone is enjoying the summer months and getting plenty of time to explore the watershed. The weather is too nice to ignore, so we are taking our monthly community meeting outside and to the Saw Kill!

Please join us this Wednesday, July 19th from 6:30-7:30pm. We will be walking along the portion of Saw Kill Creek that runs through Bard campus with Hudsonia naturalist Gretchen Stevens. This is an exciting opportunity to learn more about the ecology of the Saw Kill, take a look at one of the dams, and spend some time together outdoors as a community. Families are welcome!

If you would like more information, please email Tierney (SKWC intern) at tw4287@bard.edu.

Looking forward to seeing you there!

Check out SKWC member’s recent article on water quality!

Eli Dueker, SKWC member and Bard professor, recently published a paper on Challenges to Managing Microbial Fecal Pollution in CoastaEnvironments: Extra-Enteric Ecology and Microbial Exchange Among Water, Sediment, and Air.” . The paper adds complexity to traditional understanding of fecal indicator bacteria.   His research looks at fecal indicator bacteria, some of the same ones we monitor in our sampling program, and their interactions with both air and sediment as well as water. Improved water quality management would recognize the importance of these microbial exchanges, as well as microbial particle association and microbes length of environmental persistence.

We are excited to see such interesting research being done by a member of our community, as well as applicable to our ongoing efforts to improve our own sampling program.

Off to a busy new year!

Bard student, Isaac Yelchin, describes the “Big Night” to a full audience at our February community meeting.

After a month off, we are back and busy this February!

On February 10th we had our first water quality monitoring day of 2017! A HUGE thank you to all of the volunteers who battled the snowy weather to gather samples, and the volunteers who dedicated their Friday afternoon to process the samples. We are very excited to see how the winter month results compare to our other data.

On the 15th we had our first community meeting of the year at the Elmendorf Inn in Red Hook. There was a great turn out, and it was wonderful to see both old and new faces! We had a presentation on the assessment of doing a micro-hydro power project on the Saw Kill as we have historic dams on the Saw Kill that are currently unused for hydropower. This project is looking at the feasibility of micro hydro or dam removal–it does not take for granted that micro-hydro will be built, but does an honest assessment of what hydro power would look like at Bard’s dam.

Take a look at our meeting minutes (link) to see more information on Micro-hydro, and the current state of the assessment.

Our community conversation focused on how our local watershed can relate to our larger Hudson River watershed, as well as other communities both regionally and nationally. Looking forward to talking more about this in future conversations. Furthering community engagement and expanding our community was a large theme voiced in our community brainstorming, as well as thinking about how to improve our water monitoring program.

Coming up we have a film screening, Hudson River Environmental Futures: Film Screening & Discussion. A short film in the Hudson River: A River at Risk series by Jon Bowermaster. Riverkeeper staff and others will lead discussion at Bard College (Campus Center/Weis Cinema) on March 7, 2017 at 4:45 PM.  

Also in March, will be the Big Night! When the temperature gets just right, different amphibians come out of hibernation and head to their vernal pools. Volunteers are needed to help the salamanders cross the road safely and count. Contact us if you are interested in this important citizen science opportunity. Lastly, March will also bring our monthly monitoring program and next community meeting.

It has been a busy month already, and we look forward to only getting busier! Hope to see you out in the watershed!
