Clinging Jellyfish

Photo of a clinging jellyfish found in Narrow River in June 2018. These jellies are the size of a dime and sometimes sting. PLEASE DO NOT TOUCH THEM.

In June 2018, NRPA found two specimens of a very small species of jellyfish in Narragansett just north of Middlebridge Marina. We have positively identified these as clinging jellyfish (Gonionemus).

Clinging jellyfish are about the size of a dime and have an orange/brown cross on their transparent bodies with visible tentacles. Sometimes these jellies sting, but often they do not. PLEASE DO NOT TOUCH THESE JELLIES. From WHOI: “Reactions to stings can range from no discomfort to severe pain, redness at the sting site, and respiratory and/or neurological symptoms. Symptoms can last three to five days. While the sting symptoms can be severe, WHOI researchers are not aware of any documented fatalities associates with US or Sea of Japan populations.”

Dr. Annette Frese Govindarajan, a clinging jellyfish specialist at Woods Hole Oceanographic Institute (WHOI) has been tracking clinging jellies in the northeast US. She visited Narrow River shortly after the first two specimens were found and took samples for DNA study at her lab.

These creatures are called clinging jellyfish because they cling to eelgrass. They are not known to live in open water or high-energy environments such as beaches near ocean waves. Researchers say they generally only see clinging jellyfish in calm, quiet areas where eelgrass or other seaweeds grow. The Middlebridge area of Narrow River has a large population of eelgrass.

To our knowledge, this is the first time that clinging jellies have been found in Narrow River. They have not been documented in Rhode Island except in Potter Pond a few years ago.

25 Years of River Watch Data: Trends and Findings

Narrow River Water Quality: Trends and Findings Spanning a Quarter Century!

By Annette DeSilva and Veronica Berounsky, Ph.D.

In 1992, NRPA kicked off their River Watch program and since that time volunteers have taken measurements and collected water samples to help us assess the water quality of the Narrow River. In 2016, NRPA reached the 25-year milestone of their River Watch program. To mark the event, we have compiled and plotted all of the data to examine the water quality trends and to assess the condition of our River. A presentation was made at the 2017 NRPA Annual Meeting that highlighted the trends and findings spanning the past quarter century. The full PowerPoint presentation is available by clicking here. In this article, we will summarize many of the findings that were presented.

In the early 1990’s, water quality was on the minds of many. Sewers had been installed in Middlebridge and they were starting to be installed along the Narragansett side of the River. However, stormwater from the watershed neighborhoods was still draining directly into the River. NRPA had a strong interest in starting a volunteer water monitoring program because we were aware of high bacteria levels. Also, since there were no industries along the river (obvious point sources), a watershed watch approach to studying water quality was desired.

In 1992, NRPA’s “River Watch” program officially began with 10 monitoring locations.

Narrow River is seven miles long and its watershed is located in North Kingstown, South Kingstown, and Narragansett. The original sites (NR 1 – 10) were picked so that they would span the length of the river from Gilbert Stuart Stream in the north to Pettaquamscutt Cove in the south. The site at Sprague Bridge is closest to the mouth of the River. Over the years we added four additional sites. In 1996, Mettatuxet Brook (in Mettatuxet) was added in response to land development demand. In 2000, Mumford Brook (near Narragansett Elementary School) was added because a Rhode Island Department of Environmental Management (RIDEM) study identified this as an area of concern. Sites were added at Lakeside Rd and Lakeside Outfall (in Edgewater) in 2004 because they were near an area where a stormwater management plan would be implemented. With this data, we hope to observe pre- and post-management results.

The River Watch monitoring season runs from May to October each year. Every two weeks during the season, volunteers measure temperature and dissolved oxygen. They also collect samples for salinity and chlorophyll that are analyzed by the URI Watershed Watch Lab. Once a month, samples are also collected for bacteria, nutrient, and pH analysis. The lab analysis services are provided by URI’s Watershed Watch office, which also trains all new volunteers, supplies the monitoring equipment, compiles data into the database, and creates charts and graphs.

URI Rowing and Coach Shelagh Donohoe

by Alison Kates, Fall 2016

With a warm smile and friendly greeting, Head Coach Shelagh Donohoe welcomes me at the Middlebridge dock one chilly November morning as the URI Women’s Rowing Team is finishing up practice. Student athletes are coming in from the river. They row to the platform, lift their boat out of the water and walk it to an area for rinsing before storing it until tomorrow. All of this is fun to watch – each boat (skull) is carried by all of the rowers who fit inside and directions are coordinated by the coxswain. The students smile and seem to know exactly what they are doing.

The URI Rowing Team’s 50 members, Novice and Varsity, arrive at practice at the Middlebridge site daily by 5:45 am to practice until 8:00am. They row on Narrow River and in the Fall and Spring, and train indoors during the winter months. They consistently achieve one of the highest combined GPAs of all URI sports teams.

The Rowing team takes community service and local stewardship very seriously. They spent Sunday, November 13 improving trails at Canonchet Farm. Visit the Canonchet Farm website for great photographs of their efforts. http://canonchet.org/trails.php

The same day that the team was doing the heavy lifting at Canonchet Farm, the finishing touches were put on their new boathouse, which the team affectionately calls ‘the structure’. A sturdy steel frame covered in strong polyethylene will provide the team’s skulls with protection from the weather over the winter months. A strip of clear polyethylene along the highest point on the roof lets light into the vast space. Set back from the waterfront just past the parking area, the structure was deliberately placed out of the sightline of the scenic riverfront. The design is meant to blend in with the surrounding area, not to disturb it.

Likewise, the boat dock, installed in Spring 2016, was specifically designed and installed so as to not disturb the eelgrass and other life along the river’s edge.

The team uses one of the cottages on the Middlebridge property for storage, bathroom facilities and electric service. Even though it is filled to the gills with equipment and supplies, it’s clean, well organized and has a welcoming feel.

Lily Herberger, originally from California, walked on to the rowing team as a Freshman at URI and quickly fell in love with Rhode Island, the University and Narrow River. She rowed for four years while earning her Bachelor’s Degree, working her way up to the Varsity level. Now that she is working toward her Master’s Degree in Environmental Science, she’s helping coach the team.

Lily remembers when the team moved to the Middlebridge site from the Boathouse further up the river. She described how one day in September 2015, the team boarded the boats at the old site and rowed down to their new home at Middlebridge. Since then the team has embraced the Middlebridge site as their home.

Shelagh was delighted to talk about the Narrow River and the watershed. She has been coaching rowing at URI for 10 years. Shelagh has been involved with Rowing for decades. Her accomplishments as an athlete include winning a silver medal at the Barcelona Olympics in 1992 in the women’s straight 4. As a coach, she has guided many teams to victory, most recently the US Paralympic Team to silver at the Rio de Janeiro Olympics this summer.

Shelagh has high hopes for the future. She would love to work with the town and interested partners in the future to offer a rowing program to high school students and the general public. Shelagh loves the fact that NRPA, the Town and the team all have the same goal: protecting and helping people enjoy Narrow River.
