Construction of 7100 dam on Meadow Creek (Blackbird Creek) side.
Dam will collect contaminated runoff in the Meadow-Blackbird creeks drainage
and divert it to water treatment plant. Clean water diversion have been
constructed up gradient of the dam to divert uncontaminated water. (Iadanza,
NOAA, 1996) |

Big Spring Creek historically provided habitat for anadromous fish
spawning and rearing. Overgrazing by cattle has eliminated woody riparian
vegetation, causing the stream to widen, lowering velocities resulting in
gravels to be covered with fine sediment. Stream temperatures at the mouth
during the summer are high enough to cause a thermal barrier to upstream
migrating chinook. The restoration project of installing fencing on the lower
two miles of stream will allow willows to re-establish, reversing the
degradation. (Iadanza, NOAA, 1996) |
Example of capping contaminated tailings at the West Fork tailings
dam. There are 2.0 million cubic yards of highly contaminated mine tailings
under the cap. Concrete channel conveying West Fork Blackbird Creek (clean)
water over capped tailings pile. (Iadanza, NOAA, 1996) |
