1 The Pine Coulee Project ENVS 4000 Case Study

2 Background Historical water management problems in Willow Creek Basin: - relatively small drainage area - 60% of annual flow occurs during short spring runoff - results in the development of Chain Lakes Reservoir in 1966

3 - demand for water continues to increase as population increases ’s severe drought conditions- Willow Creek virtually dries up - Advocacy groups lobby government to construct another water storage facility within the Willow Creek Basin

4 - Planning for the project commenced in the mid 1980’s by Alberta Environment - Project initially announced in Responsibility for construction was transferred over to Alberta Public Woks, Supply and Services (APWSS)

6 Anticipated Project Benefits Increased security of supply for existing municipal and domestic water users Secure water supply for livestock and irrigation water uses Potential expansion of irrigated agriculture in Willow Creek Basin Additional-water based recreational opportunities

7 Improved potential for meeting instream flow needs – quality and quantity Increased fire protection capability in the Livingstone- Porcupine Forest

8 First project reviewed under the Canada-Alberta Agreement for Environmental Assessment and Cooperation Joint review panel under the jurisdiction of the Environmental Assessment and Review Process (EARP) Guidelines Order and Natural Resources Conservation Board (NRCB) Act

9 What is significant about the EARP Guidelines Order? A) It is no longer in force B) It was amended last week in parliament C) It was replaced by the Canadian Environmental Assessment Act D) A and C only E) Absolutely nothing!!

10 Main Components of Project Pine Coulee Dam Construction and Saddle Dyke creates a 13km long reservoir Diversion Weir on Willow Creek with a 3.5 km canal Bridge and Causeway

12 Background Studies Site Selection –13 possible sites, quickly reduced to 4 based on technical and other reasons –of the last 4 sites, the current site was deemed to be the “least environmentally sensitive” and was the most acceptable as per public consultation

13 Engineering and Technical Studies –Appropriate cost estimates –Hydrological models developed Necessary for all future hydrological assessments –Engineering constraints Geohydrological conditions Historical natural flow calculations Impervious fill within 1 km Gravel supplies from 7 to 80 kms away Rock rip rap was 80kms away

14 EIA Specific Studies Project Description Studies –Instream Flow Needs (IFN) requirements Water quantity and quality conditions required to meet the demands for instream use of water and protect river and riparian ecology (Spencer 1993) –Preliminary Operating Plan

16 Topic Specific EIA Studies –Environmental Agricultural soils Geohydrology Surface hydrology Water quality Vegetation and Wildlife Fish and Invertebrates –Socio-economic Historical resources Socio-economics (Cost-Benefit Analysis) Water use Outdoor Recreation

17 Project Issues and Potential Impacts Project description basically superimposed over existing conditions Impact assessment assumed no mitigation or enhancement Categorized as negative or positive Impacts were then rated Mitigation measures were then identified
