(In A Good Way)


Deerwood soil and water management association

27 years of activity

Field Shelterbelts

27 Years of Activity

  • Wild Life Plantings

  • Riparian Management

  • Off Site Watering


Retaining water

27 Years of Activity

  • Forage Establishment

  • Rotational Grazing

  • Residue Management


Retaining water

27 Years of Activity

Water Management

  • Grassed Waterways

  • Drop Structures

  • Small Dams

- Dry Dams

- Back Flood Dams

- Multi-Purpose Dams


South tobacco creek project

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

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)

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.

Retaining water

  • 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.
