If they had left the miners alone, they wouldn't have this problem now. All dredgers I know take an extra effort to take out the mercury and TOXIC LEAD!!

Because state wildlife officials narrowed state rules to define a suction dredge as a hose, motor and sluice box, miners are simply removing the sluice box — an alteration that leaves dredge spoils containing highly toxic mercury piling up along waterways.

Yeah the kurack itch are back at it...

Cowboy- not true about the mercury. WMA has aligned Dr Nick Ralston from N Dakota, the top scientist in his field of Mercury Methylization and he states the mercury argument is a non-starter in areas where there are high concentrations of naturally occurring selenium in the soils (like CA). Apparently, the naturally occuring Se neutralizes mercury's ability to methalize in anaerobic environments. NOAA concurs. There is zero basis to their argument. Think about it. When they were hydraulic mining and they were dumping literally tons of mercury into the rivers, NO ONE GOT SICK FROM EATING FISH. NO ONE. Now they expect us to believe that 150 years later when most of the mercury is deposited in the SFO bay, a handful of dredges in the high country is going to release more mercury into the environment than actively running hydraulic mines? I think someone is smoking something.

Dr Ralston's and NOAA's testimony is going to turn this debacle around.

lets hope so!

we have also aireated the waters and the gravels for more oxygen content witch the choked up rivers need desperately to sustain aquatic life and food for fish.

just like a garden,you cant grow a bumper crop with out mixing the soil .

mite help to give the ppl a education. i would start in the town of quicksilver. or leadville. or may be, cinnabar. they are common names of towns on the west coast i wonder why.
