WMA water withdrawal Summary (APPENDIX E, TABLE E5)
*System-wide withdrawal, all sources are not necessarily within this segment. **Water from Silver Lake supplies cities and towns in the Taunton River Watershed. Because of periodic water shortages, the Massachusetts Legislature authorized diversions into Silver Lake from Monponsett Pond in the Taunton River Basin and from Furnace Pond in the North River subwatershed in 1964 (Teal Ltd. 2000). There are also 874 acres of cranberry bog open space in this subwatershed, inclusive but not limited to WMA registered growers (UMass Amherst 1999). For the purpose of this report, a conservative estimate of water use for this bog area is approximately 7.8 MGD. NPDES wastewater discharge summary (APPENDIX E, TABLE E2)There are no permitted direct discharges to this segment of the Jones River. The Brockton Water Filtration Plant (MAG640029) currently discharges to a lagoon near to Silver Lake, however, this discharge is tentatively scheduled to be eliminated by June 2006. Use AssessmentAquatic LifeHabitat and FlowLittle if any water flows from the outlet of Silver Lake to this segment of the Jones River (Reback et al. 2004). Flow discontinuity is typical from July through December (Teal Ltd. 2000). Additionally, neither the dam at Silver Lake nor at Wapping Road are equipped with any upstream passage for anadromous fish (Reback et al. 2004). During the water quality surveys conducted by DWM during the summer of 2001, there was very little if any flow near the outlet structure near Lake Street, Kingston (Station JR104) (this reach was described as being a stagnant pool) and further downstream (Station JR103) the river was also very slow moving. GeoEnvironmental, Inc. recently completed an inflow/outflow analysis for the Jones River Watershed (GZA 2003). The report concluded “The majority of the Jones River watershed currently contains flow rates to support aquatic habitat under the current level of permitted and registered water withdrawals… Although the watershed as a whole experiences streamflows which meet flow targets, there are nevertheless specific reaches of the Jones River and its tributaries that are flow-impaired. The flow-impaired portion included the “Upper” Jones River (i.e., freshwater portion of the river above the Elm Street Dam) downstream of the Forge Pond Dam”. Stage height data for the Jones River near Lake Street crossing are available as part of the Massachusetts Riverways Programs pilot River Instream Flow Stewards (RIFLS) project (MA DFG 2005). BiologyBenthic macroinvertebrate samples were collected at two locations in this segment of the Jones River in late September/early October 1998 – near Grove Street (Station 7) and near Foxwood Lane (Station 6), Kingston (Teal Ltd. 2000). Sampling was also conducted near Grove Street in 1999 and again in May 2000. Although RPB III analyses are not available, family level taxanomic data were reported (Teal Ltd. 2000). Electrofishing in the river near Grove Street in October 1998 resulted in the capture of tesselated darter, redfin pickerel and a chain pickerel (Teal Ltd. 2000). The species collected are typically found in coastal streams with impoundments. Chemistry – waterDWM conducted water quality monitoring (DO and % saturation, temperature, pH, conductivity, alkalinity, hardness, chlorides, nitrate-nitrite nitrogen, ammonia-nitrogen and/or total phosphorus) at two locations in this segment of the Jones River between June and October 2001 (Appendix A, Tables A6 and A7). From upstream to downstream these locations are just upstream from the outlet structure near Lake Street, Kingston (Station JR104), and near the Route 106 (Wapping Road) crossing, Kingston (Station JR103). These data are summarized below. Dissolved oxygen and percent saturation With the exception of one DO measurement in the river near Route 106 in October 2001, none of the measurements at either sampling location was greater than 3.7 mg/L nor were saturations any higher than 53%. The data represent both pre-dawn and daytime measurements. Temperature The highest temperature measured in this segment of the Jones River (24.0C) was near Lake Street (Station JR104). pH, hardness, and alkalinity The pH of the Jones River was low ranging from 5.8 to 6.4 SU. Hardness and alkalinity were also fairly low at both sampling locations (21 to 26 mg/L and 6 to 25mg/L, respectively). Conductivity Specific conductance in this segment of the Jones River ranged from 129 to 201S/cm. Ammonia-nitrogen No detectable concentrations of ammonia-nitrogen were found in this segment of the Jones River. Total phosphorus The total phosphorus concentrations were moderate to high (0.039 to 0.18 mg/L) in this segment of the Jones River and were consistently higher at the upstream sampling location. The Aquatic Life Use is assessed as impaired based primarily on the lack of streamflow, which is a chronic problem for this segment of the Jones River as well as the extremely low DO/saturation conditions. These problems result from flow regulation/modification associated with water withdrawals in this segment (including but not necessarily limited to the out of basin transfer of water from Silver Lake to the City of Brockton for public water supply). Barriers to fish migration are also present at the Silver Lake and Wapping Road dams. Although pH, hardness and alkalinities were also low, these conditions are considered to be naturally occurring. The elevated total phosphorus concentrations are also of concern. Evidence of enrichment along this segment of the Jones River included abundant macrophyte growth particularly in the impounded and slow moving areas along the river. Primary and Secondary Contact RECREATION and AestheticsDWM conducted bacteria sampling (fecal coliform, E coli. and Enterococci) at two locations in this segment of the Jones River between June and October 2001 ((Appendix A, Table A7). From upstream to downstream these locations are just upstream from the outlet structure near Lake Street, Kingston (Station JR104), and near the Route 106 (Wapping Road) crossing, Kingston (Station JR103). None of the fecal coliform bacteria counts exceeded 30 cfu/100 ml at the upstream sampling location. The counts ranged from 75 to 290 in the river near Route 106 during the primary contact recreational season (geometric mean = 141 cfu/100 ml) although the highest count was in late October (410 cfu/100 ml). Field observations were made by DWM personnel during the surveys conducted in this segment of the Jones River between June and October 2001. Objectionable conditions (odors, trash/debris, algal scums, dense macrophyte cover, turbidity) were noted near the outlet structure near Lake Street, Kingston (Station JR104). Moderate/dense amounts of macrophytes/algae and turbidity were also present in the impounded reach of the river near the Route 106 (Wapping Road) crossing, Kingston (Station JR103; MassDEP 2001a). The bacteria counts were generally low in this segment of the Jones River, but the Primary and Secondary Contact Recreational and Aesthetics uses are assessed as impaired because of the aesthetically objectionable amounts of algae and macrophyte growth as well as turbidity. These conditions appear to be exacerbated by the lack of flow in the river resulting from flow regulation/modification associated with water withdrawals in this segment (including but not necessarily limited to the out of basin transfer of water from Silver Lake to the City of Brockton for public water supply). Odor and trash and debris were also problematic in the upper reach of the river. Jones River (MA94-12) Use Summary Table
