<br />There are no active, natural streams heading on or running across
<br />the project area. The Basin Ditch and a feeder ditch therefrom
<br />cross the project and irrigate lands within the project boundary.
<br />The mining and reclamation plans incorporate provisions for
<br />Maintaining uninterupted flows in these ditches.
<br />The hydrologic characteristics of the reclaimed area following
<br />mining will be very similar to those existing today in that
<br />surface drainage is now and will remain tributary to the Roaring
<br />Fork River.
<br />Plant operational water will come from the land owner's water
<br />rights in the Basin Ditch. Operational water requirements will
<br />be minimized by maximum recirculation of wash water. Surface
<br />water percolation will be increased temporarily on the areas
<br />of active operation, but will be restored to nearly original
<br />conditions by reclamation.
<br />Any surface drainage collecting on and being potentially
<br />contaminated by operation areas will be collected, settled,
<br />and skimmed for floating contamination prior to its release
<br />om the project area.
