Missouri River Reservoir System with 6 large dams managed by the US Army Corp of Engineers

DAILY US ARMY CORP OF ENGINEERS RESERVOIR CONTROL CENTER REPORT
(ISSUED AROUND 9 AM CDT)
http://www.nwd-mr.usace.army.mil/rcc/reports/showrep.cgi?3MRDTAP7

A guide assisting in reading this report:

  • Under 'Project Information' are the capacities of each reservoir referring to the dam/reservoir's elevation above sea level.
  • MP means the minimum power pool or a normal lake level- FC means flood control of the maximum height the reservoir can hold before water goes over the emergency spillways (called an "uncontrolled release").
  • Current data shows the reservoirs actual level at the time of observation- acre-feet of the lake's surface- inflow to the lake/reservoir and discharge out the dam's control structures/spillway.
  • The last figure in each project- probably the figure most telling- is the percentage of flood control capacity left in that particular reservoir/lake.



The Yellowstone River is a tributary of the Missouri River, approximately 692 miles (1114 km) long, in the western United States. Considered the principal the Missouri River, approximately 692 miles (1,114 km) long, in the western United States. Considered the principal tributary of the upper Missouri, the river and its tributaries drain a wide area stretching from the Rocky Mountains in the vicinity of the Yellowstone National Park across the mountains and high plains of southern Montana and northern Wyoming. It is the longest undammed river in the lower 48 states.
