JG,

Yeah, the CWA may actually get in the way of some stream fertilization projects.

The problem is that we have rivers that are very barren of nutrients up top (cold water, no salmon, no bugs), but very high in nutrients downstream (farms, people's lawns, golf courses). If fertilizer is put in the upper river to raise the nutrient level there, by the time it gets downstream, CWA levels for phosphorous and nitrogen will have been exceeded.

I would guess it would be easier to not permit a fertilization project than to try and regulate farm outflows and lawn fertilizers for lawns and golf courses.

Those pollutants have, and will continue, to help create a very unbalanced nutrient gradient in the rivers.

Fish on...
