The August nitrate, total phosphorus, and fecal coliform sampling results have been added to our tracking table and the Water Quality Monitoring Program page of the website.
The results for nutrients (nitrogen and phosphorus) the pollutants that cause algae blooms and excess aquatic weed growth are worse (higher) than last month. Nitrogen in particular is many times higher than any reasonable instream water quality criterion would allow and many times our nitrate target for concern. Algae blooms and excessive plant growth is currently evident throughout the watershed.
This underscores the need for the wastewater treatment plants (WWTPs) in the watershed to continue to make progress on their permit implementation schedules for nutrient reduction and for reductions from other sources such as golf courses, agriculture (including cow and horse farms), residential/commercial lawn fertilizer application and stormwater runoff.
EPA and MassDEP should also issue the long overdue two remaining major municipal WWTP permits in the watershed Somerset (8+ years overdue) and Fall River (11+ years overdue) with appropriate nutrient limitations and implementation schedules as well as implement (make effective) the new stormwater (a.k.a. MS4 permit) which is 9+ years overdue.
In June 2017, Mass Audubon and the Taunton River Watershed Alliance released Stream Continuity Assessment in the Taunton Watershed a report detailing the findings of more than 500 stream crossing assessments in the Taunton River watershed. The River and Stream Continuity Project was a joint effort of the University of Massachusetts, the Massachusetts Division of Ecological Restoration, the Nature Conservancy and American Rivers. The Project developed a system to assess stream crossings and determine the extent to which each one created a barrier to aquatic passage and natural water flow. The database generated an “Aquatic Score” that represented the degree to which that crossing creates a barrier. Crossings were ranked as “severe,” “significant,” “moderate,” “minor” or “insignificant” barriers to passage. The report with its three Appendices are available on the Mass Audubon website.
Sixteen-year-old Tauri Adamczyk of Taunton caught a 7 pound, 14 ounce, 26.5 inches long Bowfin on July 23 in the Taunton River claiming the state record for this species. This species was added to MassWildlife’s state record keeping program which covers 23 fish species two years ago. See photo on MassWildlife website
On July 16th, TRWA, the Mass Wildlife Angler Education Program, and the MA Department of Conservation and Recreation teamed up to create a day of local cultural and natural history. Dozens of Dighton Rock State Park visitors learned about Taunton River biodiversity, explored the Dighton Rock Museum, and got a fishing lesson (and loaner tackle if needed) while enjoying a beautiful day along the river.
The July sampling results are in and available at the Water Quality Monitoring Tab above (click on the sample bottles picture on the monitoring program home page). While not as bad as last year’s dry year we are seeing nitrate values 2 to 3 times the water quality target value of 0.4 mg/l. This underscores the need for wastewater treatment plants to continue with their programs to upgrade the plants to remove nitrogen and for municipalities, state agencies, and the public to identify ways to control nonpoint (a.k.a. non-wastewater treatment plant) sources of nitrogen.
The June 10 and 11 Wild and Scenic Run of River Canoe Trip was a great time with high river flows and spectacular weather both days (click on blog title for photos)! Continue reading
Don’t forget to visit the What’s Happening – Events section of the website to see the information on upcoming events and urge friends, family, neighbors, and colleagues who you think might be interested to do the same:
- Music in the Grove – Sunday, May 28th, 2-5 at Boyden Refuge;
- Overnight Canoe/Kayak Trip – June 10-11 (or either day as a single day trip);
- Angler Education / Family Fishing Day – Sunday, July 16th at Dighton Rock State Park;
- Annual Watershed Photography Contest – Submission deadline is July 15th (see rules and application on website).
Don’t forget to plan for and participate in the June 10 and 11 Wild and Scenic River Run Canoe and Kayak trip. Participate in both days and the overnight camp out at the historic Camp Titicut Reservation on Beech St in Bridgewater or either day. For more information see the events section of the website or click on the event flyer.
On Tuesday April 11th TRWA began the 2017 sampling season. Almost 30 trained volunteers sampled all 19 watershed sampling locations. Despite seasonal high flows and dilution we found elevated nitrogen levels at seven locations in April although levels were substantially lower than the peaks measured during last summer’s drought. To see our sampling results for 2017 and 2016 click on the Water Quality Monitoring tab at the top of the home page and then the picture of the sample bottles.
The Taunton River carries a high percentage of treated wastewater during the summer. Water quality and aquatic life diversity has been improving with each improvement in treatment plant effluent quality and sewer system integrity. Fortunately all the major treatment plants in the watershed except Somerset and Fall River whose permits have not been reissued yet are scheduled to remove significant amounts of nitrogen within the next 5 years. Removal of this nitrogen load will result in the next leap in ecological, recreational and economic benefit for the citizens of the watershed. As demonstrated so clearly by the successful Boston Harbor clean up; clean water not only benefits fish and wildlife but people and the economy as well.
The clean up of the Charles River and Boston Harbor now the cleanest urban river and harbor in the nation resulted in a million dollar a year fishing industry, tourism, beach openings, property value growth, and spurred unprecedented economic opportunity in the Boston Seaport District. We are fortunate to be poised to make similar progress in Mount Hope Bay and the Taunton River within the next half dozen years once the treatment plants in the watershed achieve their nitrogen removal targets. Many years ago Mount Hope Bay was once famous for its extremely productive and valuable flounder fishery. TRWA volunteer sampler efforts are supporting and monitoring this progress.
