1 Sturgeon River Watershed Alliance State of the Watershed Overview and Intermunicipal Partnership October 19, 2017 Presented by: Melissa Logan, P.Biol. Environmental Coordinator, Sturgeon River and Natural Areas Department of Environment

2 Outline State of the Watershed Issues and Challenges Municipal Partnership Successes Prior inter-municipal projects Sturgeon River Watershed Alliance Project Work Next Steps 2

3 State of the Watershed 3

4 North Saskatchewan Watershed 4

5 Sturgeon River Watershed 5

6 State of the Watershed Report Project initiated by the City of St. Albert in

7 Questions to be Answered What is the current condition of the watershed? How does this compare to past conditions? What are the critical or emerging issues? What the data/knowledge gaps that need to be addressed? What mechanisms are in place or need to be in place to maintain and protect the health of the Sturgeon River Watershed?

8 Ecological Health Indicators 15 indicators with categories for: Land Use Water Quantity Water Quality Biological health Graded POOR, FAIR or GOOD Insufficient Data

9 Sturgeon River Sturgeon River is a small, precipitation and groundwater fed prairie river 260 km in length 3,301 km2 watershed area Sub-watershed of the North Saskatchewan watershed 9

10 Sturgeon River Watershed Land Cover 71% agriculture 20% natural features 5% water 4% developed 10

11 Sturgeon River Watershed Land Use Major urban areas: St. Albert Spruce Grove Stony Plain 74.5% population in urban areas with high growth rates 11

12 Sturgeon River Fishery Now: Northern pike, white suckers and minnows Whitefish and sturgeon no longer exist on mainstem River used for spawning, rearing and feeding near lake inflows/outflows Lakes host a larger, more diverse population of fish and may provide winter refuge

13 Issues and Challenges 13

14 Watershed Issues Lake eutrophication Low river levels and flow Low dissolved oxygen Invasive species Water quality 14

15 Watershed Challenges Rapid urban development Gravel extraction Stormwater impacts 15

16 SOW Overall Grade and Key Issues Minimize impacts of urban sprawl Prevent further loss of natural areas especially wetlands and riparian areas Reduce amounts of pollutants entering the watershed - fertilizers, pesticides and road salts

17 Municipal Partnership Successes 17

18 Municipal Success Stories Capital Region Wastewater Treatment Plant (1985) Big Lake Stormwater Master Plan (2004) New floodplain elevations Pre-development release rates Lois Hole Centennial Provincial Park (2005)

19 Municipal Success Stories Water Quality Monitoring of Sturgeon Watershed NAIT Regional Natural Areas Studies Regional Water Conservation and Waste Minimization Strategies

20 Sturgeon River Watershed Alliance SRWA: Steering Committee and Technical Advisory Committee Support from NSWA 10 member municipalities Subcommittees: Water quality Water quantity Policy Ecosystem Health Watershed Management Planning

21 Sturgeon River SOW Data Gaps Riparian Health Aquatic Macrophytes Benthic Invertebrates Wetland Inventory Fish Populations

22 Sturgeon River Projects $500,000 received to date for technical projects: Water Quantity literature review of studies on the Sturgeon River; water balance for headwater lakes; modelling of flood and drought resiliency and restoration opportunities Water Quality overview of current and historic conditions

23 Sturgeon River Projects Ecosystem Health Riparian condition assessment; survey of aquatic health; barriers to fish passage; fish habitat condition; winter dissolved oxygen study; overview of gravel extraction impacts Policy overview of existing policies and legislation; recommendations for policy alignment and new policies/bylaws 23

24 Next Steps 24

25 What s Next ( ) Completion of technical studies to address data gaps Determine key areas to address with policies partnership approach Public consultation and education events Watershed management plan THANK YOU!
