Lake Ivanhoe (also known as Round Pond) is located in Carroll County, New Hampshire, in the United States. The lake has no traditional inlets or outlets. Historically, a small stream drained Lake Ivanhoe to Great East Lake, but construction filled in that stream many years ago and now drainage flows via groundwater to Great East Lake. Lake Ivanhoe is classified as "Potentially Impaired" according to the New Hampshire Department of Environmental Services water quality parameters. Lake Ivanhoe receives this designation due to its in-lake phosphorus concentration which exceeds the water quality standards for oligotrophic lakes. The Lake Ivanhoe watershed is 455 acres (184 ha) and is 64% forested. The watershed is currently 17%, developed with 59% of the watershed being buildable area. The Lake Ivanhoe shoreline is primarily composed of low density residential houses and camps (66%). The majority of these structures (88%) are within 50 feet of the water's edge. Lake Ivanhoe water quality monitoring has been collected since 1981. During this period, 16 years of secchi disk transparency data, 17 years of total phosphorus (TP) data, 16 years of chlorophyll-a (Chl-a) data, and 14 years of dissolved oxygen (DO) data have been collected. From this data, the median TP concentration is 8.0 parts per billion (ppb) and the mean transparency is 4.7 metres (15 ft).

Great East Lake
Great East Lake

Great East Lake is an 1,825-acre (7.4 km2) water body located in Carroll County, New Hampshire, and York County, Maine, in the United States. The lake is shared by the towns of Wakefield, New Hampshire, and Acton, Maine, with 45% of its surface area in Acton and 55% in Wakefield. The lake is the farthest upstream of the five headwater lakes of the Salmon Falls River, a tributary of the Piscataqua River. Water from Great East Lake flows out its dam and through the 800-foot (240 m) Newichawannock Canal into Horn Pond, then into the Salmon Falls River below Horn Pond. The widest part of the lake is in New Hampshire. The lake narrows to the east in Maine, creating the First, Second and Third basins. Great East Lake is the largest of the Salmon Falls headwater lakes. Great East Lake supports abundant wildlife, and 21 fish species including lake trout (togue), rainbow trout, smallmouth bass, largemouth bass, American eel, hornpout, white perch, black crappie and chain pickerel.Water quality monitoring data has been collected since 1974, including 29 years of secchi disk transparencies, 23 years of total phosphorus (TP) data, 20 years of chlorophyll-a (Chl-a) data and 7 years of dissolved oxygen (DO) profiles. Sampling results from Station 1 (1974-2008) show a median TP concentration of 6.4 parts per billion (ppb), a mean secchi disk transparency of 9.2 m (30.2 ft), and a mean Chl-a concentration of 1.2 ppb. The data indicates that Great East Lake is a high quality water by both the Maine Department of Environmental Protection and New Hampshire Department of Environmental Services standards.The Great East Lake watershed is located in Acton, Maine, and Wakefield, New Hampshire, and covers approximately 9,939 acres (40.2 km2). Great East Lake is part of the Piscataqua River major drainage basin and the Salmon Falls River subdrainage basin. Great East Lake flows into Horn Pond which in turn starts the Salmon Falls River at its outflow. The Salmon Falls River then flows into the Piscataqua River and into the Great Bay estuary and the Gulf of Maine. The Great East Lake watershed is currently 66% forested, 9% developed, and 52% buildable area. The shoreline of Great East Lake is composed of primarily medium density residential houses and camps (77%). The majority of these structures (64%) are within 50 feet (15 m) of the shoreline.The Great East Lake Improvement Association (GELIA) was founded in 1932 and has been dedicated to the welfare of Great East Lake, its wildlife, and environment. The nonprofit organization sees education as its primary function to help protect the lake. Great East Lake has several other programs and organizations dedicated to protecting its pristine water quality. A boat inspection program is run by the NH Lake Host Program where over 1,000 boats are inspected annually for invasive aquatic plants. There is also a weed watchers program (similar to the Invasive Plants Patrollers Program in Maine).

Horn Pond
Horn Pond

Horn Pond is a 227-acre (92 ha) water body located on the border of Acton, Maine, and Wakefield, New Hampshire, in the United States. The lake is both spring-fed and fed by the outflows of Great East Lake to the north and Wilson Lake to the east. Horn Pond's outlet is the Salmon Falls River which forms a natural border between Maine and New Hampshire and empties into the Piscataqua River east of Dover, New Hampshire, and ultimately the Gulf of Maine. Horn Pond is classified as "Potentially Non-supporting" under the New Hampshire Department of Environmental Services' revised water quality standards for oligotrophic lakes. The Horn Pond watershed covers 1,139 acres (461 ha) that is primarily forested (70%). Only 6% of the watershed is developed, with 34% buildable area. The shoreline of Horn Pond is composed primarily of low density houses and camps (51%) and undeveloped shoreline (44%). 70% of the structures along the shoreline are within 50 feet (15 m) of the water's edge.Horn Pond water quality monitoring has been collected since 1982. During this period, 11 years of secchi disk transparency data, 7 years of total phosphorus (TP) data, 2 years of chlorophyll-a (Chl-a) data, and 5 years of dissolved oxygen (DO) data has been collected. From this data, the median TP concentration is 8.0 parts per billion (ppb) and the mean transparency is 6.6 m (21.7 ft).The Horn Pond Association has been recently redeveloped and aims to protect and improve the water quality of Horn Pond.The lake is classified as a warm- and coldwater fishery and contains brook trout, rainbow trout, brown trout, largemouth and smallmouth bass, Eastern chain pickerel, brown bullhead, white perch and bluegill.

Wakefield Village Historic District
Wakefield Village Historic District

The Wakefield Village Historic District encompasses the historic village center of Wakefield, New Hampshire. It is centered at the junction of New Hampshire Route 153 and Mountain Laurel Road, which was historically the major north–south route in Carroll County. The district consists mainly of residential properties dating from the 18th to early 20th centuries, and also includes the 1836 town hall (supplanted in 1895 by the current town hall in Sanbornville), public library¸ Grange Hall, and a one-room schoolhouse that now houses the local historical society. The district was listed on the National Register of Historic Places in 1984.The junction around which the village grew was created in 1778, when the road branching northeast was laid out in the direction of Parsonsfield, Maine. Most of the houses in the district date roughly from this time to the 1820s, and are either vernacular or Federal in style. The notable exceptions are "Westlook", a Colonial Revival house built in 1929, and the Jackson Horne House, built in 1875 and remodeled in 1865. The oldest house in the district is believed to be "The Anchorage", a vernacular Cape style house that appears to date to the 1770s.The Old Town Hall was built in 1836, and hosted the town's meetings until 1895, when the new town hall was built. It has since been leased to the Congregational Church, which uses it for social service functions. The Lovell Grange Hall was built in 1918 for a chapter organized in 1892. It is a rectangular wood frame clapboarded structure mounted on concrete piers. The old portion of Wakefield Library building began as a lawyer's office in the 1860s, and was acquired by the town in 1895 as a gift from Seth Low. The newer portion, also donated by Low, was built in 1902–03. The Colonial Revival Congregational Church was built in 1958, replacing an 1831 church that burned in 1956; it is not historically significant.
