No...predators will not work. Poison works in flowing creeks, streams and rivers...it is just volume of poison versus volume of water versus costs versus risk and reward etc.
Potassium Permanganate neutralizes rotenone for instance. You apply it downsteam of where you want effects to stop.
This would not work in the Red Deer. It likely would work in Serviceberry, Rosebud etc...during low water in the Summer heat.
Another point to consider is that most predators can not survive in the same low oxygen, high temperature creeks like minnow and carp.
Stocking the Red Deer is not cost feasible nor likely to make a difference. If a short term fast solution does not eliminate enough from the small creeks to lower the likelihood of a viable population forming in the Red Deer...then it is likely too late.
