In table 18, values were corrected for available capacity (in billion gallons) at specified elevations for Pepacton Reservoir. 

In table 22, values were corrected for available capacity and dead storage (in billion gallons) at the time of the survey for Pepacton Reservoir and for the West of Hudson reservoirs in total. Corrections were also made to changes (in billion gallons and percent) from as-built values of available capacity and dead storage to values at the time of the survey.

In the abstract (page 1) and the section "Change in Reservoir Capacity Over Time" (p. 21), values were corrected for change (in billion gallons and percent) in available capacity and dead storage for the West of Hudson reservoirs in total from as-built values to time-of-survey values.

In figure 1 (page 2), the labels of East Delaware Aqueduct and West Delaware Aqueduct were corrected.

In table 2 (page 3), the placement of the footnote reference number was corrected.

Revised and reposted November 21, 2018, version 1.2

In the abstract (p. 1), the section "Change in Reservoir Capacity Over Time" (p. 21), and the summary (p. 27), text was revised to include data related to a change in elevation of the spillway at Schoharie Reservoir resulting from reconstruction during 2015.

In the introduction (p.1), the estimated as-built useable storage capacity for the combined West of Hudson reservoirs was corrected.

Table 22 was expanded to clarify that each line in the table is tied to a specific spillway elevation, and the overall change from as-built-at-old-spillway elevation to as-surveyed-at-new-spillway elevation information was added in footnote 2.
