The Kootenai Basin is an international watershed with a drainage area of ab km 2, and originates in British Columbia, Canada ().The natural hydrology of the Kootenai River is snowmelt dominated, which results in a high, sustained peak in late spring (mean flow of ∼ m 3 /s at Leonia gage station before Libby Dam operation).

The Kootenai Basin has been intensively managed since Cited by: carefully surveyed to establish suitable sites for the construction of the dam.

Each alternative site will then receive a detailed assessment to determine the size of dam that can be constructed and the corresponding storage-area-elevation relationships. With a choice of dam sites and various reservoir sizes, the hydrologist or analyst must now.

GEOLOGY OF THE AREA - The area should reveal the following: main topographic features natural drainage patterns general characters and structures of rock formations such as their stratification, folding and faulting 2. GEOLOGY OF THE SITE - LITHOLOGY. The Kootenai River population of sturgeon is a land-locked and genetically-distinct species of sturgeon found solely in the Kootenai River of British Columbia, Montana and Idaho.

They are restricted to approximately river miles in the Kootenai River basin. The Kootenai River begins in southern British Columbia, Canada in the Rocky Mountains. Altitude, as used in this report, refers to distance above the vertical datum. Transmissivity: The standard unit for transmissivity is cubic foot per day per square foot times foot of aquifer thickness [(ft3/d)/ft2]ft.

In this report, the mathematically reduced form, foot squared per day (ft2/d), is used for Size: 3MB. The Colorado River Compact laid the legal groundwork for the development of Hoover and the many other dams on the river. The writers of the Compact assumed on the basis of 18 years of streamflow measurements that the annual flow of the river averaged million acre–feet (one acre–foot equals the amount of water which would flood one acre to a depth of one foot – km³).

Some home owners living along the banks of the Kootenai River will have flooding to sections of their property. About This Location Latitude: ° N, Longitude: ° W.
