Taunton River WatershedRemarks:The Taunton River is formed by the confluence of Town River and the Matfield River in Bridgewater.The only obstruction on the main stem river is immediately downstream of this point. A partially breached damat Plymouth Street creates an impediment to fish migration during low spring flows. Under most flowconditions, however, river herring are able to pass upstream. Complete removal or further breaching of theremaining dam would insure unencumbered passage to the upper river.The main stem river possesses considerable potential for American shad development and, beginning in1969, fertilized eggs and adult shad from the Connecticut River were introduced by DMF into the Taunton.Subsequent monitoring revealed little or no success. More recently, other coastal programs have been able toestablish shad populations using other techniques such as fry stocking. Because of the substantial quantity ofunobstructed spawning and nursery habitat available in this river, it is highly recommended that Massachusettsexplore and develop similar methods to create a population and fishery for American shad.28

The first is at the head of the tide and thelast forms the only significant potential spawning area, Forge Pond. The Forge Pond dam is in poor conditionand leaks badly resulting in the loss of most of the impounded acreage. The cost of extensive repairs to thedams and fishway construction at all three sites gives this stream a low priority for development. River herringand smelt currently spawn immediately below the first dam and an active white perch fishery is carried on in theestuary. Consideration should be given to protection of existing spawning habitat and removal or breaching ofthe dams in order to create a free flowing stream habitat.31

Taunton River WatershedRemarks:Muddy Cove Brook is a small tributary to the main stem Taunton River in Dighton. Severalobstructions exist, two of which are passable at some tidal stages. The first, a tide gate at the stream mouth hasdeteriorated and allows fish to get by at higher tidal stages. The second is a concrete dam which has had itswooden stop logs removed and is passable under current water levels. A 17 foot dam blocks fish passage to a 23acre impoundment. River herring have been reported to ascend to the base of that dam. The habitat available inthe impoundment and the fact that the owner has expressed interest in installing fish passage facilities makesthis system a good candidate for development.36

The first, a low headconcrete and steel structure, was equipped with a steel plate weir-pool fishway which became badly deterioratedand was removed in 2000. A new ladder has been constructed by the Town of Dighton along with volunteerhelp and appears to be functional. Although this dam creates a spawning habitat of only 2.8 acres, a smallpopulation of river herring appears to be maintaining itself with some success. Also, smelt eggs have beenobserved in the stream below the dam in past years.A second dam, immediately upstream, blocks further passage. This obstruction creates an impoundmentof only 1.2 acres which does not justify construction of fish passage facilities.38

Thelower course is impounded by two currently impassable dams. The first, at the Harodite Company wasequipped with a prefabricated, wooden Denil ladder. This structure was washed away by high water during thespring of 1998. The upstream impoundment has been stocked by DMF with blueback herring in anticipation ofa replacement being installed. A more permanent structure has been designed for the site and is awaitingfunding. A second dam at the Harodite location appears to be avoidable by way of a bypass channel a few yardsfrom the spillway. A railroad trestle over the bypass channel, while not forming an obstruction itself, collects alarge amount of debris which could impede passage and must be cleaned annually.A fishway has also been designed for the third obstruction, a dam at the Draka factory. This structure, aconcrete and wood Denil style ladder, if funded, would make a significant amount of riverine impoundment andslow flowing river habitat available to anadromous species.40

The dam thatcreates Lake Rico was constructed by the Commonwealth’s Department of Environmental Management in 1969.A fishway was installed at the time of construction but the inability to fill the impoundment to its designelevation caused the ladder to be nonfunctional. In 2000, DMF developed a design to retrofit the fishway with anew exit at the existing lake elevation. DEM funded the modifications and the fishway now passes river herringsuccessfully. With proper maintenance and flow regulation, Lake Rico’s 215 acres should support a sizeablepopulation. Due to the low stream gradient, channel maintenance below the ladder and to the brook mouth isalso an important priority.53

Taunton River WatershedRemarks:The Nemasket River supports what is probably the largest coastal river herring population inMassachusetts. Estimates based on visual counts by volunteers have consistently exceeded one million fish peryear. The primary reason for this run’s large size is the total lacustrine and impoundment spawning and nurseryhabitat, which exceeds 5000 acres. Three dams form obstructions to passage on the river, each of which isequipped with a fishway. The first, at Oliver Mills, was incorporated into an historic site restoration project andis essentially a highly efficient set of stream baffles. The second, at Wareham Street is a large weir-pool ladderthat was designed and constructed by DMF in 1996. The last fishway is at the outlet of Lake Assawompset andis a relatively small Denil type fishway.The dam at Assawompsett is, in fact, passable for most of the early spring flows since the tailwater poollevel rises sufficiently to allow herring to swim over it. When the pool level drops, the migrating herring areable to utilize the fishway. This is an important point since the dam is in poor condition and may be replaced.A dam design that would not allow fish to ascend it could have a dramatic impact on the population because thesmall Denil ladder is incapable of passing such a large number of fish efficiently. Emergent aquatic vegetationin the impoundment above Wareham Street and other slow moving sections of the river has caused problems formigrating fish in the past and a channel should be maintained through this growth.A granite structure at the culvert connecting Pocksha and Great Quittacas Ponds has often blockedjuvenile out migration during low water periods in late summer and fall. The City of New Bedford, which usesthese ponds for a water supply, has altered the structure to allow passage under some lower water levels. TheCity, with the assistance of EOEA’s Taunton River Basin Team has designed a system to reduce sediment buildup at this location. The effectiveness of these measures should be monitored.Two other potential obstructions to passage may be encountered once fish have entered the lake system.A culvert at Route 18 which accommodates the connector stream between Assawompsett and Long Pond wasreplaced in 1993. The invert elevation of the culvert was too high for downstream migration of juvenile herringand as a result a second smaller culvert was added at a lower elevation. The effectiveness of both these culvertsin passing fish has never been assessed. Since Long Pond represents a substantial portion of the total spawninghabitat, such an assessment should be conducted.Lastly, it should be mentioned that the Nemasket River fishery is the only one in the Commonwealththat is under local control other than that granted by Section 94 of Chapter 130. The Towns of Lakeville andMiddleborough, through an amendment to an old Special Act of Legislature, have been granted the authority toregulate that fishery.

Althoughthe potential habitat available in the headwater pond is considerable, two dams present difficult fishwayinstallation problems. The first at Route 28 is associated with a culvert which would limit the efficiency of aladder and the second, at a small private impoundment, is structurally not conducive to fishway construction. Inaddition, the amount of spawning/nursery area that this pond would add to the system is small when comparedto that currently available in the Nemasket’s headwaters.62

Taunton River Watershed 36 Remarks: Muddy Cove Brook is a small tributary to the main stem Taunton River in Dighton. Several obstructions exist, two of which are passable at some tidal stages. The first, a tide gate at the stream mouth has deteriorated and allows fish to get by at higher tidal stages. The second is a concrete dam which has had its
