I think I can simplify it to two things. One is knowing the sources for the non-point source pollution in the assessment within the watershed and in doing the modelling so you can see the relative contributions from those different sources. For example, we found in the low water response plan that none of the producers of the nutrients is going to want to do reductions if they don't know what their neighbour is doing. By doing some modelling and assessment and putting some numbers on it, the rural areas will say it's all coming from the municipal point sources. The idea with the watershed-based assessment of the sources, the relative contributions lend themselves to having the discussion at the local level: who's responsible for what, and then what can we do to fix that.
I didn't touch on this in my presentation but by having that kind of an assessment framework within an area, some of our conservation authorities are looking at water quality trading programs. So instead of doing a major investment in municipal infrastructure they can look at getting the reductions and phosphorus through their rural water quality programs.
