thread_title:  Derbyshire portal 

message: The internet in general (probably copying from wikipedia) say 1831. this page which should know what it is talking about say 1838 with planning not starting until 1834. Civil Engineering Heritage: Eastern and central England says opened in 1838. The EA says here on page 140 that the thing was built 1840-41. I'm going with 1838 for now.©Geni (talk) 17:05, 1 August 2019 (UTC)

message: “Todd Brook dam, which still exists, was built to provide a water supply for the Peak Forest Canal. It is some seventy feet in height, two hundred or so broad at its base and some seven hundred feet in length, and was built in or around 1794.” 
The later 1838 date might refer to the change in its use, from providing water for the canal to supplying drinking water. Indeed, construction of the Peak Forest Canal began in 1794 and the first barges travelled along the new canal in 1796. The canal was completed in 1805.

replies: text: Reservoir is later that the canal. See here under water supply https://www.macclesfieldcanal.org.uk/interactions-part-1-1826-39 . They started talking about it in 1834 due to water supply issues.©Geni (talk) 11:46, 2 August 2019 (UTC)
replies: text: According to  it was brought into service in 1838. Does it supply drinking water? Richerman (talk) 12:44, 2 August 2019 (UTC)
replies: text: Probably not? While some canal reservoirs were taken over by water companies those that weren't tended to remain purely for canal use.©Geni (talk) 14:33, 2 August 2019 (UTC)

text: This local history site says: "Toddbrook and Combs are not reservoirs for drinking water; they are simply there to supply the canal." Martinevans123 (talk) 14:40, 2 August 2019 (UTC)

text: This, from the local council, puts the date at 1837, and gives various parameters about the dam and its lake (section 4.9.2). -- Finlay McWalter··–·Talk 15:03, 2 August 2019 (UTC)
replies: text: Quite an apposite document. Do you know if that is the latest assessment, from 11 years ago? I guess that's relatively recent in the rather slow-moving world of reservoirs. Martinevans123 (talk) 15:11, 2 August 2019 (UTC)
replies: text: So built in 1837 and brought into service in 1838 - that seems reasonable. Richerman (talk) 15:38, 2 August 2019 (UTC)

text:  This document from the local council should be used with care. For example the table 4.5 has a copy&paste error in the first and last row of the last column. Hb (talk) 16:24, 3 August 2019 (UTC)
