Description
Scope/Content: Abstract: FERC issued docket number p-20, p-2381, p-2401, p-472, p-2420, p-6509. The work consisted of surveying existing dam control monuments at the Ashton Darn, Cutler Dam, Grace Dam, Oneida concrete Dam and earthen embankment Dam, Soda Dam and Viva Naughton Dam. At least two monuments at each dam site have been assigned as fixed and arc shown as "BENCH MARKS". The field measurements have been computed and compared to a base measurement made in 1988. The values are reported in appropriate 1927 State Plane Coordinates with elevations based on NGVD '29 datum. The 1988 report showed a grid bearing between the fixed monuments and the values for the monument reported as "Bench Mark" was used as a basis for the comparison. This report includes a copy of a spreadsheet computation that shows 1988 base values, and the other measured values calculated, and a comparison noting any bearing changes, distances from the Bench Mark Monument, differences noting left or fight and differences in elevations. Please note that the left or right data shown on the spreadsheet is in reference to the base year difference and not the benchmark base line. A graphic representation for each monument, except for Bench Marks, has also been prepared. It shows the monument's position on the dam with an inset of plotted coordinates at actual scale and a bar graph noting vertical movement.
