[font "Arial"][size 2]RALEIGH, NC—Colorado's kokanee stocking program suffered a major blow recently when officials found thousands of dead fish at Vallecito Reservoir, which is used as a kokanee source for stocking 25 lakes and reservoirs statewide.
Biologists believe the kill resulted from low oxygen levels caused by high water temperatures, ongoing drought conditions and large amounts of organic debris washed into the reservoir after last year's wildfires.
Interestingly, Vallecito's rainbows, browns and northern pike were not affected, probably because these species inhabit shallower, more oxygenated portions of the lake. [/size][/font]
