Rat River Swamp wetland development feasibility study. D. Flavell and D. Sexton
Material type:
TextPublication details: MB : 1986Online resources: Abstract: The 6000 ha Rat River Swamp area in southeastern Manitoba was evaluated for potential as a waterfowl enhancement project with additional capability to protect agricultural land from flooding. A 9 cell complex with a retention reservoir is proposed. The development would prevent breakout of Rat River water overland into Joubert Creek in 70% of years and significantly reduce flows in 90% of years, thereby offering substantial protection to farmland. Waterfowl production, now very limited, would increase to about 10,000 birds per year and fall staging by migrants would reach 500,000 bird-days of use annually. The total cost of development including a 30% contingency is $6,245,000. This produces a benefit/cost ratio over a 30 year period of 0.81, considering only waterfowl benefits.
