[3] Two dams impound the water of Killington Reservoir, and the main outflow for Peasey Beck runs through the longer of the two.

A minor road from Old Hutton crosses at Beckside, and then Popplemire Lane is carried over the waterway by Blaystone Bridge.

The weir by Gatebeck Bridge provided water power for some of the production processes, and fed waterwheels and turbines.

[3] The aqueduct dates from around 1818, and consists of two shallow arches, built at an angle to the line of the canal, with curved retaining walls at either side.

[6] At Milton, the mill is attached to the rear of the former miller's house, built in the early 18th century, with an extension constructed in 1863 for Jacob Wakefield, whose initials appear on the end gable.

They bought 86 acres (35 ha) of land in 1810, in order to build the reservoir, but over-stretched themselves, and construction had to wait until they had raised more money.

The contract was initially awarded to Millington, Bainbridge & Kelly, but there was a problem with their tender, and William Seed carried out the work.

The canal company obtained an additional 26 acres (11 ha) at this time, and the original three parishes received payment.

[11] Landowners in the three parishes maintained that although they had sold the land, that did not include the fishing rights, and appointed a bailiff to enforce this in 1840.

[11] The M6 motorway passes immediately to the west of the reservoir, and Killington Lake Services, which is only accessible to southbound drivers, is situated on the bank.

The buildings were sited as far away from the motorway as possible, but were quite small, initially having parking for 64 cars and 13 heavy goods vehicles.

They are affiliated to the Royal Yachting Association and offer training to members, youth groups and people with disadvantages.

Killington was chosen as a potential site for a community hydro-electric project because of its size, as it impounds some 3.2 billion litres of water, rainfall data for over 30 years was available, and there was already an outflow pipe running through the dam 49 feet (15 m) below the surface level of the reservoir.

[10] The scheme was initiated by Cumbria Action for Sustainability, who funded the feasibility studies, with engineering design carried out by Ellergreen Hydro of nearby Burneside.

A lease for 40 years was negotiated with the Canal and River Trust, and planning permission was obtained in September 2013, to which there were no objections, in part due to the level of community involvement.

[15] A crossflow turbine was installed into the existing drawdown pipe, designed to produce 30 kW from a flow of 300 litres per second.

Of this, £21,500 was available to fund interest payments and repayment of capital to the shareholders, as well as for community benefits, which are expected to be around £50,000 over the first 20 years.

[18] In the late 1600s, it was a corn mill and some of the first machinery for cleaning grain to be used in the region was described by Thomas Machell, the rector of Kirkby Thore, who collected a huge amount of data about Cumbria until his death in 1698.

Below Gatebeck Bridge there is another weir and a long mill race to the east of the main channel within the powder works.

The finished product was packed into barrels, which were manufactured by Gatebeck Cooperage, and was transported to Milnthorpe railway station by closed horsedrawn carts.

It ran alongside Peasey Beck to the A65 road, but motive power was still provided by horses, which were shod with brass shoes to prevent the risk of sparks.

The wheel was driven by a long leat which left the beck around 550 yards (500 m) upstream, and provided a fall of 20 feet (6 m).

An annular ring was attached to the side of the wheel, which meshed with a wallower, fixed to a vertical shaft.

There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish.

Like many waterways in the UK, the chemical status changed from good to fail in 2019, due to the presence of polybrominated diphenyl ethers (PBDE) and mercury compounds, neither of which had previously been included in the assessment.
