There is a possible dam showing in the 1943 SixMaps picture at Lat. 33:43:19.12S Long 150:21:12.1E. The telling fact is the walking track visible in the 1943 photo Fig 13B (Blue Arrow) curving around to exactly where the dam is today (Red Arrow) and continuing away to the East, angling towards the SE corner of DP751646. Apparently, the Leura Golf Course Dam was built on or near to the site of the Schulze Dam for the Gladstone Coal Mine. By the time this 1943 (Fig 15) photo was taken the Schulze Dam had been abandoned for 59 years and may be the grey blob just below the red arrow tip. On the 1969 Topographic map of Katoomba a “tank” is marked on the site of the Gladstone engine. It could mean the concrete chimney footing (Fig 12) as an abandoned GI tank is not likely to have lasted 85 years.
