This etching of "The Cascade near Matlock Bath Derbyshire" was published in the Lady's Magazine. I cannot provide an accurate date. However, the original was published in "The Modern Universal British Traveller or, a New, Complete, and Accurate tour Through England, Wales, Scotland, and the Neighbouring Islands" by Charles Burlington, David Llewellyn, and Alexander Murray, published by J. Cooke, London, 1779... The articles respecting England, by Charles Burlington, Esq.

There's a similar image elsewhere on this website, in the "Bemrose Guide".
A view of a smaller cascade, this time from near Museum Parade, was published in Henry Moore's "Picturesque Excursions From Derby to Matlock Bath, 1818". The Cascade here is also described by Moore.

Whilst this is almost exactly the same as the version published in 1779 there is one minor difference which is the length of the
fisherman's rod. A third version, "A Prospect of that Beautiful Cascade below Matlock Bath" published in 1743, shows three women
in crinolines with a male on the opposite bank close to the bottom of the Cascade.

The remnants of this cascade can still be seen from Lovers' Walks today, just to the north of the Woodland Terrace houses on Derby Road near the former Matlock Bath school building. Like other springs that were discovered in the late seventeenth and early eighteenth centuries, it is now enclosed in a pipe. This one travels under the A6 from the New Bath Hotel. Although there are a number of views of the New Bath and this stretch of the river taken from Cat Tor, the cascade is hidden by trees.
