Section 779.20 (c) Continued. <br />• 1979 Investigations. Few fish were collected during the 1979 <br />survey. Tile only species captured was white sucker (Catostomus <br />commersoni). At lower Foidel a small school of minnows, probably <br />shiners, was noted. The fish appeared to be juveniles 1 to 2 <br />inches in length. These could not be electrofished or seined <br />effectively. One relatively large specimen of white sucker was <br />taken near the cattails below the dam of the. impoundment on lower i <br />Foidel Creek. Its length was 25 cm or nearly 10 inches. One whit' <br />sucker, 18 cm (7.1 inches) in length was collected in the southwest <br />arm of the impoundment. <br />In lower Fish Creek, no schools of minnows or juvenile fish were <br />noted. Electrofishing yielded a total of eight white suckers. <br />Five were less than 10 cm (3.9 inches) while the other three ranged <br />from 14.5 cm (57 inches) to 18 cm (7.1 inches). <br />The generally shallow nature of lower Fish Creek, lack of cover and <br />• absence of deep pools probably discourages the vse of this Hart of <br />the stream by fish. <br />Impacts of Mining on Fish and I•Iildlife Resources (Worse Case Situation) <br />Wildlife. Assuming the worst possible impact from mining, both <br />direct and indirect impacts to wildlife will occur as a result of <br />the disturbance to major components of the local ecosystem. Components <br />which would be disturbed by mining, activities and mechanisms fall <br />within the categories of soils, topography, vegetation habitat and <br />surface water. <br />Removal and disturbance of soils and changes in soil moisture <br />retention and other soil properties may impact wildlife as follows: <br />(i) Direct mortality or evaluation of bt:rrowing and,or ground <br />nesting mammals or avifauna from the mined area; (ii) Indirect <br />impacts due to destruction cf vegetation and other habitat substrate <br />• <br />779-240 <br />
