Notes:
1) The forecasts illustrated are based on Acres and Manitoba Hydro's estimates of manpower and a construction schedule based on a December, 2017 first unit in-service date.
2) The bar chart represents an estimate based on current regulations, present project plans, and experience with similar projects. Contractors will determine specific job requirements when the project is being built. Actual employment requirements will vary from the estimate presented above.
3) "Peak Site Workforce" refers to the maximum number of people on site, within the quarter specified.
4) The bar chart illustrates contractor site personnel (including supervisory and management positions) and Manitoba Hydro site personnel. The forecasts do not include workforce for the construction of Substations and Transmission Lines.

Upstream Boundaryof area affected by
Keeyask GS duringopen water conditions Notes:
1. Flooded Area computed as the difference between watered area during high flow conditionsbefore and after the Keeyask GS is developed.
2. Existing Shoreline based on 95th percentile. Existing (Post CRD) Inflow of 4330 m3/s
3. Project Shoreline based on 95th percentile. Project Inflow of 4430 m3/s at 159m forebay level.
4. Based on GR-4 axis configuration
5. This map illustrates flooded area immediately after impoundment.
6. This map does not illustrate additional flooded area that will occur as a result of shoreline erosionthat will occur after reservoir impoundment.
