"You would think like the old saying "$*** rolls down hill, but looking at the adisory charts, the water flowing to Deer Creek AND Deer Creek are good to go. That is strange, but maybe it somehow gets filtered."
[cool][#0000ff]Filtered? You're sorta kinda right. It's a food chain thing. The bad stuff flows into the lake from the mineralization in the surrounding mountains...and as a legacy from the mining operations. Then is is absorbed by the vegetation and invertebrates...and eaten by chubs and perch. The chubs and perch are then eaten by larger predators...and the oogies are concentrated at higher levels in the food chain.[/#0000ff]
[#0000ff]The good news for downstream waters is that a large part of the original heavy metals are either settled into the sediments of Jordanelle or absorbed into the food chain...with relatively little flowing on into Deer Creek. At least not enough to get the ecolologists agitated.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]What I have always found "interesting" is that red flags go up with almost any mercury findings in our waters...or fish. But the levels that make "eeek-ologists" freak out are only about 1/3 of the levels commonly found in canned tuna and in fresh swordfish...and other salt water species.[/#0000ff]
