Great Idea Periwinkle. That was the first thought I had when Bob mentioned digging channels earlier in the week. Heavy equipment, in-water work (shallow) is not an uncommon occurance and is certainly warranted considering the extreme condtions these fish were facing. Although, it appears that some of us would prefer putting those low-life in-mates to work. Obviously, the equipment must be steam cleaned and in good condition i.e. no leaking hydraulic hoses. Provided access, an excavator could have relieved every riffle from Barlow to G&L in a couple of days. All the vehicles parked on the gravel bar (see pictures) likely contributed more contaminates to the "habitat" than a clean excavator would have. Not to mention those of you who insist on running older model two-strokes up and down the rivers on a regular basis. Thanks for caring Bob and putting this effort together. Thank goodness for the rain and lets make sure we give the remaining spawners a break this fall once rivers are opened.
