I notice that you are quoting directly from a piece done by a ex-riverkeeper, parts of which are out of date or were never actually correct. The Hill Carr Sough is no longer a substantial stream, being blocked below the union with the Thornhill level after the 1-100 flood event of October 2000. It isn't folklore that the PDMHS cleared out the blocked tail of Magpie in 1972; it actually happened. Scientists now believe the Magpie level is taking over 50% of the Lathkills natural entiltlement. Hill Carr goes no closer to the Bradford than Mawstone Mine.
