The EIS completed March 21, 1995 cemented some restrictions on dam operations, limiting the maximum power release to , the maximum hourly "ramp-up" (increase in river flow) to , and the maximum "ramp-down" to . The minimum dam release was set to during the day and at night. Flood control releases are allowed to go higher, but must remain constant for the entire month. Because these criteria limit the flexibility of Glen Canyon Dam to meet grid demands, economic losses for the period 1997–2005 were estimated at $38 million to $58 million per year.
