[cool][#0000ff]That is a very real consideration. Saw some problems with that in Arizona, in the lakes along the Salt River drainage after a 400,000 acre fire in the watershed above. The combination of ash and the fire retardant chemicals dumped on the fire really messed up the chemistry of the whole chain of small lakes along the river. In some cases there were immediate dieoffs of some species. In other cases it raised the nutrient levels high enough to cause massive algae blooms. On Saguaro Lake, one of my favorite fishin' holes, it created a big bloom of toxic blue-green algae that forced all of the fish out of the shallow areas and into the depths. It also killed all the invertebrates in the shallow coves...like crawdads and freshwater clams. They were actually floating to the surface and the whole area would stink something awful. It took that lake at least two years to recover.[/#0000ff]

[#0000ff]I have heard from a couple of sources that fires might have been a contributing factor to big perch dieoffs at Rockport and Jordanelle three winters ago. Not sure which fire or fires were involved but it was suggested that spring runoffs from the affected areas were laden with crud that messed up the food chain in the lakes.[/#0000ff]

[#0000ff]Gee, I sure hope whatever comes down the river will be selective enough to kill carp and not the other species. Yeah, right.[/#0000ff]
