Eric absoutely an amazing post. Should go in hall of fame posts.

We have had some questions about electrofishing effectiveness so I finally broke down and got a conducitivyt meter. Around here if the pond is not too muddy or turbid with phyto bloom I can guess with good acuracy the alkalinity based on the conductivty results.

Not scientific but I have two reagents for alkalinity I use the more accurate when I see a low conducivity b/c in 90% of cases the alk is low. IN coantrast when conducivity is higher than I normally see I use less accurate reagent. It has been useful for that as well as something we report along with shock results.

So dave I would caution the conclusions (jest of EW post) but with expereince in local waters cond would serve as indicator in some situations of hardness and alkalinity IMHO.
