What was the 2010 population of the town in which the Pontook Reservoir has both a dam and impoundment? 
304
Dummer, New Hampshire
Dummer is a town in Coos County, New Hampshire, United States.
 The population was 304 at the 2010 census.
 It is part of the Berlin, NH–VT micropolitan statistical area.

 In the western part of Dummer lies the village of Paris.
Pontook Reservoir
Pontook Reservoir is a 379 acre impoundment on the Androscoggin River in Coos County in northern New Hampshire, United States.
 The dam and impoundment are located in the town of Dummer.
 The reservoir was created for hydroelectric power generation.
Hopkinton Dam and Spillway
The Hopkinton Dam and Spillway is a historic site at the eastern end of Hopkinton Reservoir in Hopkinton State Park in Ashland, Massachusetts.
 The western end of the reservoir lies in the town of Hopkinton.
 The reservoir was constructed between 1891 and 1894 as part of the city of Boston's second major water works project, the impoundment of significant portions of the Sudbury River watershed.
 The Hopkinton Dam impounds Indian Brook, a Sudbury River tributary, creating the reservoir to its south.
 The core of the dam is concrete, with earthen embankments that are bermed on the water side, with rip-rap below.
 The spillway is at the northern end of the dam, and is a 650 ft series of steps lined with granite set in concrete.
 Unlike other dams in the system, this one apparently never had gatehouses built above the chambers from which water flow is controlled. Logue Brook Dam
The Logue Brook Dam is a dam located in the south-west of Western Australia in the Darling Scarp near the town of Yarloop.
 The impoundment, a reservoir, is known as Lake Brockman. Lahontan State Recreation Area
Lahontan State Recreation Area is a public recreation area surrounding Lake Lahontan, an impoundment of the Carson River, located approximately 18 mi west of Fallon, Nevada.
 The reservoir is nearly 17 mi long and features 69 mi of shoreline and 10000 acre of water when full.
 Most of the park lies below 4000 ft in elevation and is dominated by high desert sagebrush; cottonwoods and willow trees can be found along the shore of the lake.
 Primary access points to the park are along U.S. Route 50 near the Lahontan Dam and off U.S. Route 95 in the town of Silver Springs.
 A corridor known as Carson River Ranches connects Lahontan with Fort Churchill State Historic Park. Richland-Chambers Reservoir
Richland-Chambers Reservoir is the third largest inland reservoir by surface area and the 8th largest reservoir by water volume in Texas formed by the impoundment of Richland Creek and Chambers Creek east-southeast of the town of Corsicana and south of Kerens, in Navarro County and Freestone County, Texas, USA.
 It has 330 mi of shoreline and is "Y" shaped with the dam on the eastern end of the lake. Kinbasket Lake
Kinbasket Lake (or Kinbasket Reservoir) is a reservoir on the Columbia River in southeast British Columbia, north of the city of Revelstoke and the town of Golden.
 The reservoir was created by the construction of the Mica Dam.
 The lake includes two reaches, Columbia Reach (to the south) and Canoe Reach (to the north), referring to the river valleys flooded by the dam.
 To the north it almost reaches the town of Valemount in an impoundment of the Canoe River.
 To the south it reaches upstream the Columbia River towards the city of Golden. Alqueva Dam
The Alqueva Dam is an arch dam and the center-piece of the Alqueva Mutlipurpose Project.
 It impounds the River Guadiana, on the border of Beja and Évora Districts in south of Portugal.
 The dam takes its name from the town of Alqueva to its right bank.
 It creates a large reservoir with an inter-annual regulation capacity from which water may be distributed throughout the region.
 The dam was completed in 2002 and its reservoir reached the full level, for the first time, in 2010.
 The 518.4 MW power station was commissioned in two stages, stage I in 2004 and stage II in 2013.
 The Alqueva Dam constitutes one of the largest dams and artificial lakes (250 km2 ) in Western Europe. Buffalo Bill State Park
Buffalo Bill State Park is a public recreation area surrounding the reservoir formed by the Buffalo Bill Dam, an impoundment of the Shoshone River, in Park County, Wyoming.
 The state park, reservoir and dam were named after William "Buffalo Bill" Cody, who founded the nearby town of Cody and who owned much of the land now occupied by the reservoir and park.
 The park offers camping, hiking, boating, fishing, and picnicking and is managed by Wyoming Division of State Parks and Historic Sites. Halabiye Dam
The Halabiye Dam (or Zalabiye Dam) is a proposed dam on the Euphrates in Deir ez-Zor Governorate, Syria.
 It will be the fourth and most southern dam on the Syrian Euphrates, after the Tishrin Dam, the Tabqa Dam and the Baath Dam.
 The proposed location for the dam is the narrow gap in the Euphrates valley northwest of Deir ez-Zor that is created by basalt outcrops on the left and right river banks.
 It is expected that dry areas will be brought under cultivation with irrigation water provided by the dam.
 In preparation of this project, the director of the Syrian Directorate-General of Antiquities and Museums (DGAM) appealed in 2009 to international teams of archaeologists to participate in the rescue excavations of the archaeological sites that would be threatened by the construction of the dam and the flooding of its reservoir.
 These excavations were expected to be carried out between 2010 and 2012.
 The sites that are threatened are located in the area that is projected to be flooded by the reservoir and in the area where construction works for the dam will take place.
 Important sites that are threatened include the Roman–Byzantine sites of Halabiye and Zalabiye that were first fortified by the Palmyrene queen Zenobia in the 3rd century CE.
 The lower town of Halabiye will be partially flooded by the reservoir and the Syrian government is cooperating with the United Nations Development Programme (UNDP) and UNESCO to limit the impact of the dam on this site as well as on Zalabiye.
 Other threatened sites include Bronze Age Tell Ma’dan and Tell Humeyda with Ubaid, Uruk and Byzantine material.
 Given the current instability in the region, it can be assumed that the project has been postponed.
