diversion for the succeeding accounting year shall not exceed three thousand two hundred cubic feet per second on an annual basis. The average level of Lake Michigan will be based upon the average monthly level for the period from 1900 to 1976. (c) When river stages approach or are predicted to approach bankfull conditions at the established flood warning stations on the Illinois Waterway or the Mississippi River, or when further increased diversion of water from Lake Michigan would adversely affect water levels necessary for navigational requirements of the Saint Lawrence Seaway in its entirety throughout the Saint Lawrence River and Great Lakes-Saint Lawrence Seaway, water shall not be diverted directly from Lake Michigan at the Wilmette, O'Brien, or Chicago River control structures other than as necessary for navigational requirements. (d) The Chief of Engineers shall conduct a study and a demon- Study and stration program to determine the effects of the increased diversion demonstration on the levels of the Great Lakes, on the water quality of the Illinois program. Waterway, and on the susceptibility of the Illinois Waterway to additional flooding. The study and demonstration program will also investigate any adverse or beneficial impacts which result from this section. The Chief of Engineers, at the end of five years after the enactment Results, of this section, will submit to the Congress the results of this study submittal to and demonstration program including recommendations whether to continue this authority or to change the criteria stated in subsection (b) of this section. (e) For purposes of this section, controllable diversion is defined Controllable as that diversion at Wilmette, O'Brien, and Chicago River control diversion. structures which is not attributable to leakage or which is not necessary for navigational requirements. SEC. 167. (a_) The Secretary of the Army, acting through the Chief Hydroelectric of Engineers, is authorized and directed to conduct a study of the most power resources, efficient methods of utilizing the hydroelectric power resources at study. water resource development projects under the jurisdiction of the 42 USC 1962d-5g. Secretary of the Army and to prepare a plan based upon the findings of such study. Such study shall include, but not be limited to, an analysis of— (1) the physical potential for hydroelectric development, giving consideration to the economic, social, environmental and institutional factors which will affect the realization of physical potential; (2) the magnitude and regional distribution of needs for hydroelectric power; (3) the integration of hydroelectric power generation with generation from other types of generating facilities; (4) measures necessary to assure that generation from hydroelectric projects will efficiently contribute to meeting the national electric energy demands; (5) the timing of hydroelectric development to properly coincide with changes in the demand for electric energy; (6) conventional hydroelectric potential, both high head and low head projects utilizing run-of-rivers and possible advances in mechanical technology, and pumped storage hydroelectric potential at sites which evidence such potential; (7) the feasibility of adding or reallocating storage and modifying operation rules to increase power production at corps projects with existing hydroelectric installations;
