Arnagill Tower

Arnagill Tower is a historic building in Ilton-cum-Pott, a civil parish in North Yorkshire, in England. The folly was built in 1824 on Masham Moor, to a design by John Foss. It is a round tower, with walls terminating about 10 feet (3.0 m) from the ground, to resemble a ruin. It has one storey, and contains a doorway and three windows, all arched. It is described by Gwyn Headley as a "Gothic mood piece", linked with the nearby Druid's Temple. It was grade II listed in 1986.

Roundhill Reservoir

Roundhill Reservoir is situated near Leighton Reservoir in North Yorkshire, England. It was constructed by Harrogate Corporation early in the 20th century. Water from the reservoir is fed into Yorkshire Water's grid. Roundhill reservoir is overlooked by a stone tower, Carlesmoor sighting tower, which was used to triangulate the end points of a water tunnel from the reservoir to Harrogate. It is one of several Colsterdale towers. Although not in Nidderdale, the reservoir is within the Nidderdale Area of Outstanding Natural Beauty.

Leighton Reservoir

Leighton Reservoir is a reservoir which drains via the River Burn to the River Ure in North Yorkshire, England. It neighbours Roundhill Reservoir and is about 4 miles (6.4 km) west of Masham. It takes its name from the nearby village of Leighton. Work on the reservoir was started by the Leeds Corporation in 1908, and although the major parts of the building process were over by March 1926, the final cementation was not completed until 1941. The reservoir was allowed to fill with water over the winter of 1926–1927. A newspaper report from 1910, estimated that the final cost of the construction would be £437,000 (equivalent to £56,347,000 in 2023). Although the Leeds Corporation intended to build another reservoir in Colsterdale on the River Burn, this never came to pass, and Leighton Reservoir was constructed on two tributaries of the Burn; Pott Beck and Spruce Gell. Water from the reservoir is used to compensate for abstraction from the River Ure. Although not in Nidderdale, the reservoir is within the Nidderdale Area of Outstanding Natural Beauty. Leighton is accessible for fishing and has a car park. The reservoir is on land owned by the Swinton Estate and they stock the waters with fish. Like its near neighbours in Upper Nidderdale, the construction of Leighton reservoir (and Roundhill) necessitated the building of an industrial railway to bring in materials for construction. A 2 ft (610 mm) 6-mile (9.7 km) railway was built from the north end of Masham railway station where a transhipment yard was located to transfer freight between the narrow and standard gauge lines. The line opened in 1905 and was closed by 1930. The reservoir has a mean depth of 36 feet (11.1 m), a surface area of 91 acres (37 hectares), a catchment area of 5,600 acres (2,260 hectares), and it lies at an elevation of 617 feet (188 m) above sea level.

East Nidderdale Moors

East Nidderdale Moors is a Site of Special Scientific Interest (SSSI) in the Pennines, North Yorkshire, England. Part of East Nidderdale Moors is within Yorkshire Dales National Park and part of it is within the Nidderdale National Landscape. East Nidderdale Moors extend from the peak of High Ruddes in the south (above the town of Pateley Bridge) to the peak of Flamstone Pin in the north (above the hamlet of Caldbergh). This area is protected because of the important moorland and peatland habitats here and because of the diversity of bird species. The full name of this protected area is: East Nidderdale Moors (Flamstone Pin - High Ruckles) SSSI. One of the streams that flows through this protected area is called the River Burn. East Nidderdale Moors SSSI includes Colsterdale moor, Masham moor, Lofthouse moor, Dallowgill moor and Pateley moor.

Fountains Earth

Fountains Earth is a civil parish in the county of North Yorkshire, England. The principal village in the parish is Lofthouse, and the parish also includes the hamlet of Bouthwaite and the northern part of the village of Wath. The population of the parish in the 2011 census was 197. The parish occupies the eastern side of upper Nidderdale. It is bounded on the west by the River Nidd and Gouthwaite Reservoir, which separate the parish from Stonebeck Up and Stonebeck Down. In Wath, at the southern end of the parish, a stream known as Dauber Gill separates the parish from High and Low Bishopside. To the north and east large areas of grouse moor extend into the neighbouring parishes of Ilton cum Pott and Laverton. Historically Fountains Earth was a township in the ancient parish of Kirkby Malzeard in the West Riding of Yorkshire. The township took its name from Fountains Abbey, which owned the land in the Middle Ages and established granges at Lofthouse, Bouthwaite and other places in the township. Fountains Earth became a civil parish in 1866. From 1974 to 2023 it was part of the Borough of Harrogate, it is now administered by the unitary North Yorkshire Council. The parish now shares the Upper Nidderdale grouped parish council with the parishes of Stonebeck Down and Stonebeck Up.
