Water District Drinking Water Source
Cocheco River Watershed
Baxter Lake lies across Rochesterís northern border with Farmington, near Four Rod Road. The predominant development along the lake is the Grandview Campground, which includes dozens of campsites, trailers, boat slips, and facilities. A dam blocks the outflow of the lake at its southwestern corner. Here Rickers Brook passes the dam and flows into a small marsh, adjacent to Four Rod Road. The brook makes its way southeast, flowing through a small forested area between Meaderboro Road and Sampson Road. It passes several homes as it crosses under Walnut Street. Rickers Brook runs through another mile of forest until it meets Howard Brook.
Rochester Reservoir lies across Rochesterís border with Barrington, along Strafford Road. There is very little development along the shores of this impoundment, except for the dam at its northern end, and the Rochester Water Treatment Plant. Rochester Reservoir is a source of drinking water for the town. Howard Brook flows over the reservoir dam and runs east, through a small marsh area. The brook crosses Estes Road, where it passes near to several homes. It meets Rickers Brook not far from Estes Road, and the two smaller brooks combine to form Axe Handle Brook, which continues east through a half mile of forested and emergent wetland. Axe Handle Brook passes under Washington Street, and flows past several homes and a large gravel pit. It passes through a culvert under the Spaulding Turnpike and then turns south, along the highway. The brook then passes several housing complexes and a series of onramps for the turnpike, where it flows into the Cocheco River.
Hanson Pond is located in Squanamagonic Park, near Hansonville Road. This small pond is relatively undeveloped, except for the park facilities on its eastern bank. A small stream flows out of the southern end of Hanson Pond, and flows past numerous homes in a residential area along Flagg Road. The stream flows through a large farm field, and then a small marsh that borders a subdivision on Flagg Road. Finally the stream flows into the Isinglass River, which enters Rochester from Barrington. The river passes close to the subdivision and makes a dramatic turn south. It flows for a mile, passing many homes and a small commercial lot, before passing under Gonic Road and crossing back into Barrington. The Isinglass River passes into Rochester again south of the Turnkey landfill on Rochester Neck Road. The river passes under a bridge on this road and then joins the Cocheco River.
Clark Brook originates in a small forested wetland in eastern Rochester, north of the Spaulding Turnpike. It flows south along Blackwater Road, through the backyards of several homes. The brook then crosses under Blackwater Road and the Spaulding Turnpike, and crosses into Dover, on its way to join the Cocheco River.
The Cocheco River flows for over nine miles across the entire length of Rochester, beginning near several gravel pits, where it enters from Farmington. The shoreline of the river is developed for almost its entire length in Rochester beginning with dozens of homes and a few farms along Farmington Road. The river meanders dramatically as it passes a large junk car lot and then passes under a bridge on Little Falls Bridge Road. It turns south and runs past several large subdivisions and industrial sites between Farmington Road and Chestnut Hill Road. The Cocheco River passes under a bridge on the Spaulding Turnpike, where it enters a marsh area between commercial sites on North Main Street and a residential area to the east. The river passes the Spaulding High School as it enters downtown Rochester. It flows past dense residential neighborhoods and passes under two bridges, before encountering a dam in the heart of downtown. The river passes the dam and makes a large turn past the Rochester Fairgrounds. The Cocheco River runs past more dense residential areas as makes its way out of Rochester center. It crosses under a bridge on Gonic Road, and another on the Spaulding Turnpike, as it passes several businesses. The river passes another dam on Main Street and continues south, with several fairways at the Rochester Country Club on its west bank, and the sewage ponds of the Rochester Wastewater Treatment Pant on its east bank. The Cocheco River flows past the Turnkey landfill on Rochester Neck Road, and borders several large farms, as it passes into Dover near a large gravel pit at the southern tip of Rochester.
Salmon Falls River Watershed
Heath Brook drains a large emergent wetland between the New Hampshire Northcoast Railroad tracks and the Spaulding Turnpike. The brook flows around a rail yard and then passes through a large wetland on either side of the railroad tracks. The wetland is bordered by a large farm on Old Milton Road. The brook passes under this road and Milton Road in an area of highway exit ramps, and then turns east into a wide emergent wetland. Heath Brook flows through this wetland for over half a mile until it passes through a culvert under Salmon Falls Road, and flows into the Salmon Falls River.
The Salmon Falls River forms Rochesterís eastern border with Maine. The river flows out of the southern end of Spaulding Pond, which is formed by a dam at the Spaulding Fibre Company facility on Spaulding Avenue. The river flows over the dam and flows south past several large subdivisions, and two junk car lots along Milton Road. The Salmon Falls River passes under Flatrock Bridge, and forms a small oxbow near a farm on Salmon Falls Road. The river continues past a dozen homes along Salmon Falls Road, and then turns east. It next enters a residential area in East Rochester, and passes under a bride on Highland Street, where it forms a small reservoir behind another dam. The river then twists and turns through a forested wetland area near several cemeteries, and then enters a half mile stretch of forest. The Salmon Falls River continues to meander dramatically as it bends around a large subdivision off of Salmon Falls Road, and enters a series of wetlands. The shoreline becomes less developed as the river continues south, passing several farms and then crossing into Somersworth.
