    1. Retaining Water (In A Good Way)

    2. Deerwood Soil and Water Management Association

    3. Field Shelterbelts 27 Years of Activity • Wild Life Plantings • Riparian Management • Off Site Watering

    4. 27 Years of Activity • Forage Establishment • Rotational Grazing • Residue Management

    5. 27 Years of Activity Water Management • Grassed Waterways • Drop Structures • Small Dams - Dry Dams - Back Flood Dams - Multi-Purpose Dams

    6. South Tobacco Creek Project From Implementation to Research • Monitoring Hydrology (flow) • Partners: • Local Farmers, Land Owners • Federal & Provincial Governments • Universities • Monitoring Water Quality (sediment, nutrients, pesticide, bacteria) • Land Use Trends

    7. South Tobacco Creek Conclusions • 30% control of headwaters produced a 19 to 25 % reduction in peak flows for spring and summer events. ( 15 to 20 yr payback in municipal savings ) • Conservation Tillage did not increase herbicide loadings. • Conservation Tillage did not decrease runoff volumes in a clay loam soil. ( BMP’s have been designed for wind and water erosion control, not nutrient movement)

    8. South Tobacco Creek Conclusions • Small dams can act as nutrient sinks with natural limitations. ( Once a natural equilibrium is established, the nutrients need to be removed either through irrigation, organic matter removal , or high flows ) • Escarpment Streams tend to be naturally high in nutrient loadings due to topography, soils, and stream bank erosion.

    10. Tobacco Creek Model Watershed Canadian Water Network Funding Accepted as 1 of 4 Research Nodes June 2011 Collaboration with University of Manitoba $600 K Research Call for 2012- 2014 Howard Wheater Consortium (U of Sask. /EC) Joseph Culp Consortium (University of New Brunswick/EC)

    11. Tobacco Creek Model Watershed Additional Research University of Manitoba Natural Sciences and Engineering Research Council (NSERC) To Develop Environmental Fingerprinting Techniques for Sources of Sediment and Phosphorous Manitoba Rural Adaptation Council (MRAC) Preliminary Survey for Wetland Potential -In Conjunction with the International Institute for Sustainable Development (IISD)

    12. Activities 2012 • Baseline Monitoring • Hydrology sampling- 12 new sites, 70 sampling days • limited flows beyond June 28 • Water Quality – 73 samples, 35 sampling days • reduced sampling as flows dropped.

    13. Tobacco Creek Model Watershed The Challenge- Retain More Water Funding Licensing Location Design

    14. On Farm?

    15. In Stream?

    16. More Escarpment Storage ?
