'Till Next Time

Final Blog Entry from Emily Pitman
Hamilton College '15

It's amazing to think that a little over two months ago I was just beginning my internship with North and South Rivers Watershed. This summer I gained valuable experience and a greater understanding of the ecological relationships within the river and the watershed. 


Through my internship, I had the opportunity to work on a variety of field projects with ecologist Sara Grady. Fellow interns Margo, Sara, and Alex and I assisted with multiple projects including collecting samples for an ongoing experimental study of dock shading impacts, analyzing samples to determine the ecological effects of harbor alterations,  and completing surveys of Phragmites and other invasive species in the surrounding harbors. While the summer began with Sara patiently instructing and informing us on proper techniques and scientific names, we gained the knowledge and confidence to conduct the surveys independently. Not only have I successfully developed navigation skills necessary to get me to the various locations, but I can also correctly identify Japanese knotweed invasive species while driving!

A significant aspect of my internship was conducting the preliminary research for potential shellfish restoration in the North and South Rivers. Historically blue mussels (Mytilus edulis) had a significant presence in both rivers, but there are currently significantly decreased populations. I conducted field surveys to determine current shellfish populations in the North and South Rivers, held interviews with government officials regarding existing regulations, and discussed the experiences from similar restoration projects in the Bronx River and Martha's Vineyard. The information I gathered will be used in NSRWA's efforts to establish new blue mussel populations in the rivers for water purification and habitat remediation. My research exposed me to the complexity of federal regulations surrounding water resources and the influence of minor changes in ecological factors. It was fascinating to gain an understanding of the necessary steps for such a project, and I look forward to following NSRWA's development of this project in the following years. 
  
I greatly value the friendships that I made during my internship and owe a great thanks to all those who assisted me throughout my time with NSRWA. Sara H., Alex, Margo, and I had a lot of fun throughout the summer, from playing with squirt guns at the Great River Race to frequent ice cream stops after working in the field. Janet Fairbanks, Joe Stradzes, and Russel Clark deserve additional thanks for providing their time, knowledge, and boats that allowed me to conduct the necessary studies in my research of existing shellfish habitats. I am so grateful for my experience with North and South Rivers Watershed Association and look forward to hearing of the continued successes of the organizations and other interns. It's not a 'goodbye' as I leave for college, it's more of a "I'll see you soon' and I can't wait until the next time I'm on the rivers.

Notes From Wampanoag Canoe Paddle 2013

Notes From Wampanoag Canoe Paddle 2013
by Peter Kelly-Detwiler

What a difference one year (and a lot of rain) makes.  Last year, the canoe trip from Scituate to Dighton was something I had not undertaken in about 35 years.  We went in May, after a very dry spring.  And I had not appropriately described the trip to the other paddlers in terms of the mud, poison ivy, logs to cross, and potential for getting lost.  That escapade resulted in: enough exposure to the ivy that two of us itched for nearly a month (I had never had subcutaneous itching on my palms before); a canoe with a broken bow; a two hour bushwhack up the wrong stream; and hours of pulling canoes through mud and grass that was marked as water on the Google map.

So this year, we were ready.  There were two crews.  Nik Tyack had his team of four – who went about the trip with style – and I had my team of four as well: two ex-rowers and one of their sons (Clay – who had been with me last year).  These were tall, strong guys who a) knew what they were getting into and enjoy hardship and, b) know how to move a boat. 

The week before, my friend from Kentucky had emailed north to say, “I hope this trip is as hellish as you have advertised.”  As it turns out, it wasn’t.

The first day saw us leave with a huge contingent from the Driftway for the beautiful North River paddle. 
First Day with everyone paddling the North River starting at the Driftway!

With the tide, we canoed and floated our way up into Norwell and Marshfield, and took a short break at Couch Beach.  From there, our group broke off and started to paddle with more determination: our goal was to make it to the Herring Run Park on Route 14 by late afternoon, so that we could loop back to the paddler party at the Tyack’s house.

We fairly flew up the river with the tide, and found the outlet to the Herring Brook on the first try (compared with last year, where we paddled past it, into the appropriately named Swamp Brook, cut our way with loppers through heavy brush until the stream ran out on us, then backtracked to the right watercourse).  The first part of the Herring Brook was easy.  Last fall I had dropped down from the Herring Park and cleared the section with loppers.  We easily followed the trail for some time, until we lost it completely and ended up on a stream that simply did not exist last year.  With the higher water, the area that usually has two braided streams now had additional flows, and we followed one of those additional braids.  So the loppers had to come out once again as we cut new trail. 

Tiring of that, I left the group and walked through chest high grass to find the larger stream (so that all of last fall’s work would not be useless), and eventually found it, about 50 yards away.  We dragged the canoes through the grass to this channel, climbing in and out of the canoes to maneuver around tight corners, and made it to the Herring Brook park by late afternoon. 
Chest High Grass Portage
The party was a nice end to the day, and we met up with Nik’s team there to coordinate the events of the following morning.

Day two saw the two teams meet early the next day (having skipped about 5 miles of paddling and portaging that my team is determined to try the next time – in two years), and put in at the outlet from Stetson Pond.  Shortly, we were hauling canoes up over the train tracks, and putting in again in the cranberry drainage ditch that takes one to the swamp before Monponsett Pond.  Nik’s team determined that the wiser course was to portage canoes through a construction site and down a road to the water: my team was determined to give the swamp a try.  Truth be told: it’s my favorite part of the trip, because it is the one place where you really cannot tell exactly where you are.  We paddled the wrong way once for about 50 yards, but turned around once we reached a dead end.  In places, it’s so dense in there you cannot see 10 yards ahead.  The best way to determine the correct course is to watch the water and see which direction the flow is going.  This year’s higher water made that task easier.  Then you cut through the bush with the loppers, check the channel again, and so on.

The swamp was also made easier than last year because I had been there once before.  There were occasional lopper marks on branches, confirmation that we were going the right way. 
Following last year's lopper marks!

Rubberized gloves helped too.  The only poison ivy I contracted was on my legs.  When you cut the stuff, it falls into the soup around you – pretty much a guarantee.

Coming out of the swamp, we paddled the two Monponsett Ponds and Stump Brook, where we met up with Nik’s team.  The next section – which was a mud slog last year – went about twice as fast this time, and we quickly powered through to Robbins Pond in East Bridgewater. 

There, we waited for Nik’s team.  He planned to spend the night camping at a friend’s place (where all of his gear had been dropped), which was less than two hours’ paddle away.  As it was early afternoon, our team decided to push on and see how much distance we could cover before dark.  And we did cover distance.

Robbins Pond drains into the Satucket River, where the flow was strong and water level high.  Areas where we had to pull and drag last year now had several feet of water in them: fallen trees from last year passed under our keel, and the new blowdown from Sandy and the February Blizzard was not as bad as I had feared.  Once or twice we had to deviate from the river and drag canoes through mud and grass – once scaring a fawn in the process, but the detours were minimal.

We reached the old mill in East Bridgewater around 5 PM.  The water running through the sluiceway was moving at a good clip, but the portage would have taken a long time, so we opted to run a canoe through the sluiceway – a task easily performed last year with minimal flow.  We snapped all of the dry bags to the gunnels, attached a rope to the canoe and let it slide into the spillway.  And then the canoe got stuck.  We tried to pull it back out of the flow, but the rope snapped and the canoe shot through.  The good thing about the Satucket is that it’s full of snags, and the canoe did not go far, resting in the high reeds.  We opted not to repeat the experience with the second canoe, and ended up lifting it – as well as all our gear - over the six foot dam, and launching below.  Aside from a few things getting damp, the gear in the other canoe was none the worse for wear.
Running the Canoes through the Spillway

We entered the Town River in late afternoon, and paddled until 8:30 in the evening, pulling over near the Plymouth Street Bridge in Bridgewater.  Ramen Noodles and other fare were on the menu.  But my iphone restaurant locator said otherwise.  Warm fare and cold beer (it HAD been a hot day in the low 90s) beckoned us, so we walked two miles in to Bridgewater to the 99 Restaurant.  I have to say, the $9.99 specials have it all over Ramen Noodles.

I also have to say that although we had been in the river, we were kind of odiferous, and it was a good thing we were away for other diners.  A two-mile walk back with a near full moon seemed to take no time.  Fireflies lit up the fields as we walked, and we made our way through a field into the woods to our campsite hidden on the river.  Sleep was not long in coming.

The next day was about mileage.  The Town River yields quickly to the Taunton, the current gets wider, and the bridges more frequent.  Great Blue herons croak noisily around every turn, as one passes through woods and meadows, until one ultimately reaches the commercialized and industrialized area of Taunton.  It starts with the McDonalds, which is on the right and has a nice place to land canoes.  Bad junk food tastes really good after a half day of paddling, but the best thing is the unlimited cold drink – free refills!

This day was also about being decidedly unfriendly to the other boat, and watching for potential places for ambush.  The trick in this game is to come up fast from behind when the other paddlers are not paying full attention, and then hit the bow of their boat just as they are passing a log in the stream or brush projecting from the bank.  Appropriately struck, the victim’s canoe gets jammed into the bushes, with the occupants lying flat on their backs to protect life and limb.  Inappropriately struck, the ambusher becomes waylaid instead.  Either way, there is great potential for humor among grown men acting like fools, and sons watching (and participating).  Thirty years melts away and in our minds we are briefly in college again, doing silly things, and laughing so hard that we can barely breathe.

From the McDonalds downstream, it’s solid paddling through the industrial landscape and soundscape – the noise of trucks and cars is omnipresent for miles - until Dighton and the take-out at Shaws boatyard, which we reached around 4 PM. A quick jump into brackish water was intended to take away the worst of our sweat and stink, before we jumped into the car of Sarah Head, the intern who pulled the short straw to come get us.  A conversation with Sarah a few days later confirmed that our effort was futile – the car carried a distinct odor for a few days after she dropped us off.  Such is the price of being an intern for the NSRWA…

Thanks to all who supported us.  In the final tally, we raised just shy of $10,000 to support the activities of the NSRWA.  Come join us next time.

Wompanoag Paddle '13

This years Wompanoag Paddle was a great turnout! Founded by the Tyak's, this water stride is a non-competitive, breathtakingly scenic event that begins at the Herring River off of Lady's Way in Scituate and ends - for most people - around 10 miles up the North River at the Tyak's very hospitable and beautiful residence. For those who can handle a more strenuous distance, like Peter Kelly-Detwiler and Nick Tyak - the founder of this paddle in fact - the entire paddle would continue for 3-4 more days!

Executive director of the NSRWA, Sam Woods, and I canoed along side kayaker Dorie Stolley, a representative of her business Three Birds Consulting as well as the US Fish and Wildlife Services at which she served as a wildlife biologist. 

The paddle itself was one of remarkable landscape and serene nature. The wind was endless but the surrounding beauty served enough of a distraction. Along the bank of the North River about 5 miles into the paddle there was a camping site that participants were allowed to make a pit stop at to grab a bite or take a dip. Sam, Dorie, fellow intern Sara Head, and I tested the water out after working our upper bodies to the brink. The temperature of the river was quickly adaptable and the current was strong enough that when we swam against it we wouldn't move foward at all. Like natures own resistance pool! 

The Wompanoag Paddle was a great experience that I and many others were fortunate enough to share together. I look forward to participating in it again next year!

Boat Tour with the Town Managers

Scenic Tour of the North and South Rivers with Local Town Managers
By Emily Pitman

         Last Friday I had the opportunity to go out with the managers of the towns located on the North and South River. While it was initially rainy, the clouds cleared in time for Norwell Jim Boudreau, Duxbury Rene Reed, Scituate Patricia Vinchesi, and Marshfield Rocco Longo to accompany Sam, Sara and I on the tour. The boat ride was provided by Marshfield Harbormaster Mike DiMeo.

Our group included (top row, left to right) Mike DiMeo, Jim Boudreau, Sara Grady, Rene Reed, (bottom row, left to right) Samantha Woods, Patricia Vinchesi, and Rocco Longo.

       Once on the water, we discussed various successful progressions and projects that have been completed within the individual towns, including the Greenscapes education initiative and Scituate water restrictions. The town managers also described various water issues that the individual towns are facing, and potentially how the members of the Watershed can help facilitate ways to solve the problems. Communication between the town managers and the North and South Rivers Watershed is critical in preserving the rivers and the surrounding area. I personally look forward to hearing about the continued successes in the towns and am excited for the next time that I will be able to discuss ways in which the Watershed Association can help engage the community!

And Then There's Margo

Hello there! My name's Margo and I, too, am a summer intern for the NSRWA! I can now say the acronym pretty fast. Much progress. I lived in Charlton, MA (near Worcester) until I was about 15 and then moved in with my dad in Marshfield, MA. I attend Marshfield Public High School here and will begin my senior year come fall! I plan on going to college in California for geology, particularly geochemistry, and studying abroad to further explore our monumental planet and its inhabitants.

I've always had an affinity for the natural world and the diverse life it holds. When I was a kid I remember learning about the Ring of Fire in elementary school and was completely mesmerized and astounded. Ever since then I dream of becoming a volcanologist! Usually when I say that people go, "Oh so like Dante's Peak?", yes except unlike Mr. Brosnan I'm a real scientist ;-D

Working with the NSRWA for the past few weeks has already been an awesome experience with only greater and more memorable things to come! Lookin forward to it indeed! Later!

Intern Number Four, Alex Rozen

My name is Alex Rozen and I am the final summer intern for the NSRWA! I am from Carver, Massachusetts and I graduated from Carver High School this spring. I am very excited to begin my first year at Worcester Polytechnic Institute in the fall! Although my major is currently undecided, I am very interested in environmental science, and I am so happy to have the opportunity to help out at NSRWA.

On Thursday the 13th of June, Sara Grady, Emily Pitman, and I went out to Mill Pond to set up quadrats around clumps of purple loosestrife plants along the bank of the pond made by the Mill Pond dam.  Purple loosestrife is an invasive species of purple flowering plant that is native to Europe but was introduced to North America in the 1800s. It thrives in shallow wetlands, so Mill Pond is an ideal location for a takeover by the plant. Our mission is to release a purple loosestrife eating beetle, the galerucella, into the Mill Pond area to suppress the current invasion.

Now that the quadrats are in place, we will return to Mill Pond to record the plotted purple loosestrife and then monitor these marked plants when the galerucella are released.

I am excited to see the results of the galerucella release and all of the other things in store for us interns this summer at the NSRWA!

Another New Summer Intern-Sara Head

Hi everyone! My name is Sara Head and I am one of the NSRWA's new summer interns.  I am from, and currently reside in Marshfield, MA.  For those familiar with the area, I live on Damons Point, located across from the mouth of the North River and The Spit.
Naturally, I developed a love for the rivers and surrounding ecosystems from years of kayaking and boating with my family.  This passion led me to study Environmental Geology in college.  I attended Eckerd College, on Florida's Gulf coast for my freshman and sophomore years, and recently transferred to Bridgewater State University.  I will be a senior this fall, and plan to continue my education in Paleontology and Paleoclimatology later in grad school.

For now, I am the secretary for BSU's Geological Society, where we host guest lecturers and go on field trips to significant geological sites.  We recently went to the Big Island of Hawaii in the Spring to study volcanoes and magma composition!

As an intern, I am extremely excited to put my love for nature to work in the field!  The NSRWA currently has several projects underway, including the removal of Japanese Knotweed, which I took part in with my fellow interns on my first day.

Japanese Knotweed is a highly invasive bamboo-like plant that grows mostly along rivers and streams.  As the name implies, the plant originated in Asia and has now made itself quite dominant here in our watershed communities.  The Knotweed may look pretty, but it actually limits biodiversity of species in an ecosystem, deeming it an "invasive species".  The plant is spread when it is uprooted and transported to new locations, usually through waterways.
Last Thursday (June 6th), we removed nearly all of the Japanese Knotweed from South River Park in Marshfield, hopefully allowing for more plant life to flourish there.  Removal of the leaves and stalk will prevent further photosynthesis and the remaining roots were treated with an organic Sodium Chloride herbicide.

For more information on Japanese Knotweed, please check out these websites:

I am very excited to continue working with the NSRWA and get my hands dirty with more projects, and I look forward to blogging more about my experiences!

Until next time,
~Sara Head
