Document Summary
Week 7 lecture 2 (lecture 19) midterm 2 (no notes) Week 7 lecture 3 final lecture on irrigation, navigation and dams. Modern dams are larger and planned to meet multiple water resource needs: recreation (most popular primary purpose in the us, flood control. In many instances, the priorities for users have shifted after a dam was built: creates conflict amongst users. In eastern canada, most dams are hep (quebec especially), whereas in bc, mix of dam types and in saskatchewan/manitoba/alberta, lots of irrigation, recreational and water supply dams. In the us dams mostly exist for recreation which is surprising. (designated primary use is largely recreation) Quebec, newfoundland, new brunswick; dams predominantly for hydroelectric power. Looking to the prairies, (west of 100th meridian) purpose of the dam shifts to primarily irrigation or flood control [many are multi-purpose particularly in alberta; irrigation, flood control and recreation].
