flexibility for the Corps to address species needs under the combined project authorities.
ACTION AREA
The combined action area for this consultation includes the area directly and indirectly affected by the
three projects under consultation. This includes most of the Missouri River main stem, the Kansas nur -ions
River, and portions of major tributaries and the Middle Mississippi River where listed species are
influenced by the Corps' MR Operations, KR Operations, and BSNP. MR Operations primarily
affects the area of the Missouri River and its reservoir system from the headwaters of Fort Peck Lake
in Montana downstream to the mouth of the river near St. Louis, MO, river mile (R1MI) 0 at the
confluence with the Mississippi River. The point furthest upstream where the Corps regulates Missouri
River flows is at Reclamation's Canyon Ferry Dam in Montana when the reservoir is in the flood pool.
MR Operation begins at Fort Peck Dam in Montana and continues downstream to Gavins Point Dam
on the South Dakota- Nebraska border 811 mi (1304 km) upstream from the Missouri River's
confluence with the Mississippi River. Additionally, tributary inflows into and downstream from the
System influence operations. Therefore, the action area for this biological opinion is the Missouri Ri
Basin. However, the thrust of the opinion will be cn„� „° a to *�° T� T'con��f j Rj�7°r == =ain}p fr�11 the
r
headwaters of Fort Peck Lake to its confluence with the Mississippi River.
The Corps operates and maintains the Missouri River BSNP from Sioux City, lA, at RM 735 to the
mouth. Tributaries that may influence MR and KR Operations and the Middle Mississippi River below
the confluence which may be affected by operations also are included within the action area. The
action area for KR Operations includes the river from its formation at Junction City, KS, below Milford
Reservoir on the Republican River, downstream about 170 mi (274 km) to its mouth and confluence
with the Missouri River at Kansas City, Kansas and Missouri.
Overall management of these three projects falls under the purview of the Corps' Northwestern
Division in Portland, Oregon, the Missouri River Region in Omaha, NE; the Omaha District in Omaha;
and the KCD in Kansas City, MO. The Corps' Reservoir Control Center in the Missouri River Region
Office was established in 1954 to plan, regulate, and coordinate the operation of the Missouri River
Main Stem Reservoir System, as well as provide oversight on the regulation of the Corps tributary
reservoirs and the flood control regulations of Bureau of Reclamation (Reclamation) projects authorized
for flood control. Operations, management, and technical support is provided by the District Offices.
