(2) List any endangered or threatened animals which are supported by the river and river corridor environment. Include location, if known. Check whether these animals are endangered [E] or threatened [T] species and if they are significant at a national [N] or state [S] level.

Currently, known endangered or threatened amphibians, invertebrates, or reptiles have not been documented in the Isinglass corridor. However, a new law prohibits anyone from possessing Blandings, Spotted, and Wood Turtles. All three species occur along the Isinglass. The Wild Lupine found in the corridor supports the state- and federally-endangered Karner Blue Butterfly.
 

(3) List significant wildlife habitat which is supported by the river or to which the river is integral, for game and non-game wildlife populations. Identify if the habitat has been determined to be exceptionally diverse, very diverse, or moderately diverse by the NH Department of Fish and Game or the US Fish and Wildlife Service.
 

The attached Wetlands map shows numerous wetland areas within the corridor which attract birds,  reptiles, and amphibians (see vegetation list below). The large forested areas in the corridor offer habitat to animals with more extensive ranges and provide cover and browsing feed for other animals through much of the year (see Unfragmented Lands map).

(4) Determine if the river corridor is important for the movement of wildlife between large habitat areas. If it is, explain why.

In a number of sections, the River serves as a corridor between unfragmented parcels (see Conservation Lands and Unfragmented Lands map). The upper five-mile natural section is particularly important as a wildlife area and for movement of wildlife between adjacent large habitat areas. The unsettled woodlands that extend north from the River corridor to the Parker Mountain area are extremely valuable. This peak is the most prominent in the Blue Hills range, a small southeastern New Hampshire highland. This expansive area supports many large mammals such as Moose, Black Bear, and White-tailed Deer.

The large undeveloped area along the northwestern bank of the Isinglass extending from the Route 126 bridge to the Route 202 bridge also connect with the extensive habitat described above. Hilly terrain, wetlands, and a terrace of inactive beaver ponds mark this section. Bobcats have been seen here in recent years as well as Moose, Black Bear, and White-tailed Deer. These animals move along the corridor downstream of Route 202. Bear and Moose are rarely seen below the Green Hill Bridge section. Coyotes cover virtually the entire River corridor west of Route 125. Most of the wildlife travel below Route 202 takes place on the northwestern banks, which are the least developed. However, all these species cross the River regularly.

Downstream, the River corridor offers good habitat to Deer in several places. The absence of reports of Black Bear and Moose suggest that the development that has occurred on the Rochester side of the River has impacted habitat for large animals.

(2) List any vegetative communities supported by the river and the river corridor environment which have been identified as “exemplary natural ecological communities” by the New Hampshire Natural Heritage Inventory. Include location, if known.

The richness of vegetation reflects the diversity of land types within the corridor. Swamps, beaver ponds, and wetlands contribute various sedges, Black Gum/Red Maple community, and species such as the Inflatable Bladderwort. Managed forests provide space for the herbaceous plants that provide food for wildlife, such as Pin Cherry. Newly opened areas in Tree Farms which have been predominantly pine offer opportunities for trees such as Black Spruce to grow more rapidly.

(d) Fish Resources

(1) List the fish species commonly found in the river.

Many of the species listed below are not considered common but are found in the Isinglass River corridor and are indicated by an asterisk.
 

American Eel Brook Trout Brown Trout Rainbow Trout Atlantic Salmon Eastern Chain Pickerel Bridled Shiner Common Shiner

Blacknose Shiner* Fall Fish Long Nose Dace Black Nose Dace Common Sucker Creek Chub Sucker Brown Bullhead Margined Madtom*

Common Sunfish Redbreast Sunfish Bluegill Smallmouth Bass Largemouth Bass Yellow Perch Swamp Darter

(2) List any endangered or threatened fish species which inhabit the river. Check whether these fish are endangered [E] or threatened [T] species and if they are significant at a national [N] or state [S] level.

The Blacknose Shiner, which occurs in the Isinglass mainstem, has not yet been designated but has a very limited presence in New Hampshire. It could qualify for listing in the future.

(3) Describe the presence and location of spawning beds, feeding areas, and other significant aquatic habitat for fish populations. Determine if the habitat is exceptionally diverse, very diverse, or moderately diverse as determined by the NH Department of Fish and Game or the US Fish and Wildlife Service.

The fish habitat in the Isinglass is judged to be very diverse by NH Department of Fish and Game biologists. This diversity is facilitated by the River’s high water quality, an abundance of riparian vegetation, and variable flow velocity which provides a range of bottom substrates from rock/cobble to mud.

Areas of importance fit into two categories: those that receive stocked trout for anglers and those that are stocked with sac fry Atlantic Salmon as part of the NH Department of Fish and Game’s effort to restore a salmon population in tidal rivers in southeastern New Hampshire. The Isinglass is a freshwater component of this program.

 The area most valued for trout stocking is the River reach between Routes 126 and 202. Annually, tsocked Rainbow Trout number about 2500 and Brook Trout about 3000. Due to the excellent public access there, angler actively pursue fish in the area. The stocking of sac fry Atlantic Salmon in the Isinglass also occurs along this reach as well as along Green Hill Road in Barrington. It is expected that the stocked fish will complete the early stages of their life cycle as sac fry, parr, and then as smolt when they will run to the ocean to mature. It is hoped that they will return to spawn in the Isinglass/Cocheco.

(4) Indicate whether the significant fisheries found in the river rely on natural reproduction or a stocking program. If fish populations rely on a stocking program, indicate whether they are partly or wholly dependent on the program.

Anadromous fish in the Isinglass system are currently restricted to one species, the Atlantic Salmon. Atlantic Salmon are present only as introduced sac fry and parr as a part of a program whose goal is to establish a sustainable population for the Isinglass/Cocheco system. With favorable conditions, fish may mature to run to the ocean as smolt and later return to spawn. The Isinglass lower reach (below the Locke Mill Falls) would be accessible by adult salmon after they ran the fish ladder in Dover, passed a natural ledge obstruction, and through Watson Road lower dam (all on the Cocheco River). It is possible that an adult salmon raised in the Isinglass system could ascend that stream and seek spawning habitat. The ability of salmon to pass Locke Mill Falls is less certain. The Cocheco/Isinglass, along with another coastal system, the Lamprey, are target streams for the New Hampshire Department of Fish and Game’s ten-year old federally-supported program directed at the restoration of Atlantic Salmon to coastal New Hampshire waters.

Evidence of natural spawning in the mainstem of the Isinglass is speculative. However, there is documented natural spawning in some of its tributaries. NH Department of Fish and Game personnel have observed clear evidence of natural trout spawning in Nippo Brook and a small unnamed stream that enters the Isinglass near the junction of Routes 202 and 126 in Barrington. No doubt, natural spawning of Brook Trout is possible in other tributaries and may be occurring in the upper reaches of the mainstem when the vegetative shading of the stream is heavy.

Based on NH Department of Fish and Game’s information on natural spawning in the Isinglass, it appears that the significant trout fishery is partly dependent on stocking. The majority of anglers who frequent popular fishing sites along the highway access points are pursuing stocked trout.

(5) Is the river a viable anadromous fish resource? If yes, identify any on-going or planned restoration programs.

The River is currently being used as a nursery stream for the restoration project as described above.

(e) Water Quality

(1) Check the state’s water quality classification which applies to this river or segment under state law.

Class A      Class B

(2) According to readily available information, what is the actual water quality of this river under the state's water quality standards?

Class A      Class B

(3) If the river is not currently supporting its water quality classification, identify the existing major causes of deficient water quality (e.g., industrial or sewage pollutants, agricultural fertilizer run-off) and possible corrective measures (e.g., regulations, enforcement, local, and use controls).

For this study, the dam discharge at the southeastern end of Bow Lake marks the beginning of the Isinglass River. During the summer of 2000, volunteers of the Isinglass River Protection Project performed field sampling. Sampling included the Isinglass and two of its tributaries, the Mohawk River and Nippo Brook. Data sheets from the NH Volunteer River Assessment Program for last summer’s results are included in the Appendix. Monitoring sites are depicted on the Ground Water Hazards map.

The Isinglass currently supports the Class B water quality designation at all of its monitoring locations. From a water quality perspective, the Isinglass’s two chief beneficiaries are the Cocheco River and the Dover Water Works. First, the Isinglass plays a crucial role in contributing to the Cocheco River’s water quality . Second, the City of Dover withdraws water above the confluence of the Isinglass with the Cocheco. The Isinglass helps replenish Dover’s public well water supplies.

There were monitoring sites  along the Isinglass that had E. coli and Dissolved Oxygen (DO) samples that would border or fall outside the Class B water quality classification:

Monitoring site, 01-Mhb, along the Mohawk River above the confluence with the Isinglass River had samples that came close to the DO 5 mg/L mark for Class B water quality classification:

• On 09/09/00, 10:10 AM, station 01-Mhb recorded DO samples of 5.27 mg/L and 55.6% saturation. Observations included comments of a beaver dam with stillwater above the sampling station that may contribute to these readings.
• On 10/07/00, 1:30 PM, station 01-Mhb recorded DO samples of 7.02 mg/L and 66.3% saturation.
• On 11/05/00, 1:30 PM, station 01-Mhb recorded DO samples of 8.88 mg/L and 75.8% saturation. Observations included comments of water flowing over the beaver dam above the sampling station.

• On 07/07/00, station 08-Isg recorded E. coli 320 CTS/100ml using EPA method SM 18 9213 D.3.
• On 10/10/00, station 08-Isg recorded E. coli 600 CTS/100ml using EPA method SM 18 9213 D.3. No observable evidence for the cause of this high reading was documented although this site is downstream of extensive wetlands.
• With the exception of monitoring station 08-Isg, the Isinglass River at Route 126 Bridge, E. coli samples from all other Isinglass River monitoring stations were 120 counts per 100ml or below using EPA method SM 18 9213 D.3.

Briefly describe the natural flow characteristics of the river, including natural periodic variation in flow (e.g., spring run-off and summer flow amounts) and frequency and duration of flood events. If applicable, describe purpose of and flow variations caused by impoundments, significant diversions, or channel alterations, including inter-basin transfers. Indicate which segments of the river are free-flowing.

There are no current or historic stream flow gauge sites directly on the Isinglass River. However, using other USGS stream gauges in the Piscataqua-Salmon Falls basin, namely the Lamprey River near Newmarket (#01073500), Mohawk River near Center Strafford, NH (#01072850), Cocheco River at Dover (#01072880), and Cocheco River Near Rochester (#01072800) the IRPP has estimated monthly average and median cubic feet per second (cfs) as well as monthly median cubic feet per second per square mile of watershed. Median flow values are a much less biased estimator of monthly flows than are estimates of mean flow. The monthly flow estimates are transposed using the watershed area that contributes to each respective gauge location and the area of the Isinglass watershed, then adjusting for the period of record available for each of the gauges to produce estimates of the historical discharge for the Isinglass River.

The low flow statistic, 7Q10 describes the lowest seven day-average flow that is likely to be seen at a given location on an average of once every ten years. That is, in any given year there is a 1/10 chance that the 7Q10 will occur. In determining the monthly median flows for the Isinglass River, four gauges with similar underlying geology and watershed characteristics were used. However, of those gauges only the Lamprey gauge had a sufficiently long period of record to produce a reliable 7Q10 statistic. The transposed 7Q10 for the Isinglass River would be 1.97 cfs. Impoundments at Bow Lake and Ayers Pond are not likely to impact the flow estimates since the Lamprey has a similar degree of impoundment.

 In 1978 and 1982, the USGS made several flow measurements in the Isinglass River. In August 1978, a low-flow event of 6.6 cfs was recorded. In April 1978, flow was recorded at 383 cfs and 298 cfs in April of 1983. By the method presented above, the April 1978 average flow was 289 cfs and 382 cfs for April 1983.

 From the outlet of Bow Lake the Isinglass River flows freely to the confluence of the Cocheco River. The Isinglass River watershed is approximately 75 square miles. The major tributaries of the Isinglass River include the Mohawk River, Nippo Brook, Berrys River, Green Hill Brook, and the outlets of Hanson and Ayers Ponds. In Rochester, the Isinglass flows into the Cocheco River and then proceeds to the Piscataqua River.

(g) Open Space

Briefly describe, give the location and identify the type (e.g., floodplain, forested, etc.) and type of ownership (i.e., public or private) of significant areas of open space in the river corridor. Describe and include the location of any protected land parcels within the river corridor (e.g., state parks and forests, national forest lands, municipal parks and conservation easements.

High-quality natural and scenic resources characterize the Isinglass River. The shore is largely forested, (primarily in natural vegetation); and the corridor largely undeveloped. Riparian land use is mostly active forest management and scattered residential housing. There are no state or federal parks or forests along the Isinglass.

Beginning at Bow Lake in Strafford, the River flows through Barrington and ends at its confluence with the Cocheco River. Various streams flow into the Isinglass including unnamed tributaries, the Mohawk and Berrys Rivers, and Ayers and Nippo Brooks. Nowhere in the River corridor is the flood plain more than 200 feet wide.

Segment 1, Strafford Corridor (IRM 17.9 - 12.1): From Bow Lake to the Barrington town line, the Isinglass corridor runs through primarily private, largely forested and undeveloped land. Immediately below the Bow Lake Dam, the River flows under the Province Road bridge, which predates the dam. Residences, two small businesses, one general store, and one craftwork studio lie on the northeasterly side of Province Road near the bridge. Beyond these structures, the River runs through deciduous forest for .3 miles until opening into a flat, forested wetland just northwest of the Route 202A bridge. Here the River separates into multiple channels which converge as the River passes under the Route 202A bridge (IRM 17.4). Extensive wetlands lie to the southeast of the bridge.

 Below these wetlands, the River runs through deciduous forest along high, steep banks. There is a housing development lying on the northwesterly side of the River, accessed off Route 202A. A natural vegetated buffer on a high bank separates house lots from the River. All of the house lots are located uphill from the river channel. From this point, the River runs through privately held, undeveloped forestland. The River divides into two channels above the Foss Mills Site (see Historic Sites map) at IRM 14.3, converging some distance below the old mills. Foss Mills is sited in forested uplands and punctuated by the breached remains of the 1780s mills and old cellar holes. The Foss Mills Site is a seventeen-acre conservation area leased by the Town of Strafford from the NH Water Resources Council. Pig Lane, a closed Class VI town road, “crosses” the River at this site. Pig Lane has snowmobile bridges over both its channels today and local recreational groups hope to include bicycle access.

Below the Foss Mills Site, the Isinglass continues to flow through privately held, undeveloped land, joined by No Name Brook. The River broadens into a wetland area at the confluence of the Isinglass with the brook descending from the Huckins Mill Pond. It then regains a defined channel with high banks. Public Service Company of NH power transmission lines cross the River about one-half mile from the Barrington town line. The River continues to run through privately held undeveloped forest land throughout this area and cannot be directly accessed from a road. Nearing the Barrington town line, the terrain flattens as the River nears its confluence with the Mohawk, opening into an extensive wetland area across the town line. Parshley Lane, off Route 126 in Strafford, extends near the River in this area, marking the site of one of the area’s first homesteads. Only the Parshley family cemetery remains today. Residential development is clustered at the Route 126 end of the road, well away from the River.

Segment 2, Barrington Corridor (IRM 12.1 - 4.0): The Strafford-Barrington town line is at the confluence of the Isinglass and Mohawk Rivers. The confluence of the Isinglass with Nippo Brook at IRM 12 marks the point at which the Isinglass becomes a fourth-order stream. Extensive wetlands are found where the Isinglass crosses the Barrington town line as it flows toward Route 126. The Isinglass then flows along the northerly side of Route 126 and west of Route 202 for a little over two miles. Along this stretch, the southeastern side of the River is scattered with residential use, woods, and open wet areas. On the northwesterly side are undeveloped forest and wetlands, part of a 1000+ acres of unfragmented land area (see Conservation Lands and Unfragmented Lands map).
 
Just below the Twombley’s Grist Mill ruins (also called Locke Mill), the Isinglass passes under the Route 202 bridge. Moving rapidly through the mill’s abandoned sluice, the water broadens into a narrow floodplain where Ayers (AKA Betty's) Brook joins the River (IRM 8.5). This area is mostly flat, forested land on the northwestern bank and residential on the southwestern.
From Route 202, the River roughly parallels Scruton Pond Road for approximately 3.5 miles. The banks are generally high with a few seasonally wet floodplain areas. In this section of the River are abutments of three pre-Revolutionary bridges. The most westerly of these led to the Barrington Town Farm and Tuttle’s Fulling Mill (See Historic Sites map and Barrington’s Town Farm in the Appendix). Presently this site is a managed woodlot of approximately 300 acres belonging to Harlan Calef. Across the River, below the old bridge abutment is a Certified Tree Farm of approximately 50 acres also owned by the Calef family.

Continuing downstream, a fifteen-acre parcel on the southeastern bank has recently been acquired by the Town of Barrington. This lot has approximately 200 feet along the River. No management plan is currently in place. At the junction of Scruton Pond and Brewster Roads, a 55-acre parcel owned by Jim and Ann Schulz is under conservation easement and is a Certified Tree Farm. A footbridge spanning the River and relying upon the historic abutment is maintained by the owners for local use.

 As the River turns northeast from Scruton Pond Road, it is bounded by two small wetlands formed from the outlet of Winkley Mill Pond. The pond’s containing-berms were fully breached in the mid-1980s. In all other areas, the banks are very high and steep. Below the pond, the water flows shallowly and rapidly over rocks and through rapids as it passes the abandoned Winkley Mill. Most of the northern bank here is residential housing buffered, with one exception, by natural vegetation.

Above the Green Hill Road bridge (IRM 4.7), the River broadens briefly and then moves downhill over rocky terrain for the next half-mile, passing an inactive gravel pit well-buffered by forest. This property is owned by Robert Hussey who permits informal public access for recreational use on its 200+ acres.

Segment 3, Rochester/ Barrington Corridor (IRM 4.0 - 0.0): As the Isinglass flows northeast into Rochester near Flagg Road, it passes a clustered housing development on the northwest bounded by 11.37 acres of open space deeded to Rochester. Also along the bank is a deeded Public Service of New Hampshire property of 2.34 acres where power lines cross the River (approximately IRM 3.5).

As the River flows southeast again, it passes through the abutments of an abandoned Boston & Maine railbed. A deeded easement on a 50-foot forested buffer along the Isinglass begins at the abutment where the River can be forded on horseback and used for fishing and boating access. This space also offers opportunity for rough hiking (see Recreation Sites map).
From IRM 2.0 - 0.8, the River’s southern bank is within Barrington. On the northern shore of this segment, Turnkey has a created a forest management area of over 100 acres within their 1200 acre site with excellent recreational and scenic opportunities (see Recreation Sites and Historical Sites maps). Although the area is in active forestry management, it is not under conservation easement and cannot be considered permanent open space.

At IRM 0.4 the River flows under the Rochester Neck Road bridge. There, the River is narrowly buffered from a former Pike Industries gravel operation. Just downstream of the bridge, the City of Dover draws water from the Isinglass for an adjacent town well. Otherwise, the southern bank of the River is private land in agricultural and scattered resdiential use.
The confluence of the Isinglass and the Cocheco is at IRM 0.0. There is a conservation easement on the Gabriel Farm at the confluence.
