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
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)!
The TRWA Sampling Volunteers collected another complete data set from all 19 monitoring locations in May. The results to date for 2017 as well as last year’s results may be found on the Water Quality Monitoring tab.
Spring due to cold water and high flows generally is the time of year with the highest water quality. In May the rivers exceeded the nitrate level of concern by a small amount at three locations and a more significant amount at the Matfield River location. The fact that high flows didn’t cause bacteria problems is very good news reflecting favorably on … Continue reading
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 … Continue reading
TRWA issued its 2016 Water Quality Report Card. TRWA monitors 19 locations along the Taunton River and its tributaries. A major concern for the watershed is nutrient pollution from nitrogen. Nitrogen levels in the main stem are often 2-5 times recommended levels and much higher in tributary streams. High nutrient levels fuel algae and rooted aquatic plant blooms limiting biodiversity in the watershed. Currently about 66% of the nitrogen load comes from wastewater treatment plants which are being required to upgrade to remove excessive nitrogen loads from their discharges over the next five years.
This past May, a dead adult sea lamprey was observed at Oliver Mill Park in Middleborough. The fish had migrated up the river to spawn on the Nemasket and having completed its life cycle, died and was washed up on the banks. It was 30” long.
There are two lamprey species native to Massachusetts waters, the American Brook Lampry (Lethenteron appendix) (which is a threatened population in the state) and the Sea Lamprey (Petromyzon marinus).
The fellow … Continue reading
The TRWA is pleased to announce it will be funding a technician to formally investigate the Diamondback Terrapin (Malaclemy terrapin) population of Assonet Bay located in Southern Massachusetts. This population and its nesting beach have been documented for several years, but no rigorous studies have been conducted to determine and record the abundance, sex ratio, or age structure of this population. Such a study would provide crucial information for conservation and management of this, and other populations … Continue reading
