Declassified UFO / UAP Document
Proposal for work regarding lake drainage
AI-Generated Summary
A 1946 engineering report detailing the technical requirements and excavation volumes needed to lower a lake's water level. It addresses both the physical drainage process and local concerns regarding groundwater.
This document, dated July 21, 1946, is a technical proposal regarding the drainage of a lake. The author, identified as Lieutenant Kärfisch [illegible] Dastall, outlines the necessary steps to lower the water level by approximately 2 meters. The proposal includes specific engineering requirements: clearing the area between 200 and 220 meters from the old dam structure, and excavating approximately 900 cubic meters of gravel and clay, as well as 300 cubic meters of mud, followed by 150 cubic meters of stone. The author notes that to fully drain the lake, an additional 2-meter reduction would be required. The document also records that the maximum water depth is 2 meters, with a depth to the solid bottom of 4.8 meters. Finally, the author acknowledges concerns from the local civilian population regarding the potential impact on groundwater levels. A postscript adds that a depth of 5.5 meters was later discovered at point 15, referencing an attached document, Bilaga 8.
