In 1850 Chorley was growing, like many other towns in the area, . A larger population and more industry meant there was increased demand for water and Chorley's existing small reservoirs were inadequate. So, in 1850 Chorley Council decided that a new reservoir would be built at Anglezarke, below a house called High Bullough. John Frederic Bateman of The Chorley Water Company designed it and started work on it in 1850. It was named Chorley Reservoir

The reservoir has a surface area of 6.9 acres with a perimeter of 0.6 miles. It has two embankments that are, in total, 330 yards long, one to the north and one at the southern end. It can hold 48.3 million gallons of water and is approximately 40 feet deep. Water outflowed from the northern end and was carried by a 12 inch pipe down to a holding reservoir near Crosse Hall Lane. That pipeline goes below what is now Anglezarke reservoir.

In 1857, Liverpool started work on 3 new reservoirs at Rivington and took responsibility for Chorley's water supply. To avoid confusion with the reservoir near Chorley, Chorley reservoir was renamed and took the name of the house above it, namely High Bullough. High Bullough House was later renamed "Manor House", the name most people refer to it as today. With regard to High Bullough reservoir, well to me it is, and always will be "Chorley Reservoir".

The reservoir is now disconnected from the water supply but will still contribute to Anglezarke Reservoirs supply in times of heavy rain. High Bullough's only overflow, that being at the southern end, discharges into Anglezarke Reservoir, just north of Lister Mill Quarry.

Footpaths Although it is possible to do a circular walk of the reservoir it can also be included in the walk round Anglezarke reservoir. Whatever you chose, ensure you visit Jacob's Ladder.

Below the surface Other than Brook House, which was lost because of the north embankment being erected nothing else was lost below the waterline. However, though not technically beneath the water, I have three photos of the pipeline from High Bullough to Chorley Reservoir. In the 1980s the stone tunnel collapsed and repairs had to be made. The collapse occurred a little to the west of the valve on Anglezarke's west shore. Thank to Boyd Harris, who has kindly supplied me with three photo's of the orininal stone tunnel. They are the last three below.

The left picture shows the start of the steps from the path by the reservoir, very difficult to spot. Half way up these are in better condition - but need care when using them - see Jacobs Ladder section further down for an old photo of these steps

 

 

Chorley is the most inaccessible of the eight reservoirs, seen here from Healey Nab. On the right the top of the overflow

Jacob's Ladder

Due to the location of the reservoir, a ladder was built so that water company employees could quickly access the reservoir. Near Jepson's Farm , the company built a recess into the cliff face, stone lined it and then added three or four ladders (see photo left). Then a series of stone steps lead down to the reservoir. Today the whole area is overgrown, the steps slowly getting covered and the last short section to the ladder is treacherous when it is wet and muddy. It also appears that the bottom section has been filled in - but that may just be plant growth covering it
