6.0 FISH STUDIES <br />• 6.1 Methods <br />Fish were sampled 3 times dicing the year, corresponding to the benthic <br />sampling periods. These xere late October, late March, and late July. The <br />same sampling locations xere chosen to correspond xith benthic sampling areas <br />but included a much larger azea and more varying habitats. Details of the area <br />chazacteristics, its size and the length of time sampled are given in Table 6-1+2• <br />In general, the habitats sampled were the entire stream width for approxi- <br />mately a 100 foot section. Tnis included shallow neazshore areas, riffle areas, <br />pools, and undercut bani:s. There were no large deep pools in the four study <br />areas, and a small length of undercut bank occured only in the uppermost <br />sampling area, NF-1. <br />Differences betxeen stations,- although all stations included some <br />• of the same type of fish habitst, made it im possible to pick stations that <br />were very similaz and yet meet some of the other goals of the overall <br />sampling program. Thus, the lower two stations (NF-3 & 4) xere most <br />similar in being generally riffle-type water with some small pools or <br />pockets, being generally shallox, having no overhang from trees, and having <br />a cobble substrate that had been disturbed by bulldozer operation xithin <br />the past feu years. At the lowest water levels in July however, station <br />NF~1 was very shz?low and there xas one deeper pool at NF-3. <br />The two upper stations were more similar to one another and different <br />from the two lower stations. Both had somexhat deeper water and more <br />flow since the}~ were above two of the ditches depleting water from the <br />lower stations. Both had tree lined banks and the cobble bottom had not <br />• beer. disturbed within recent yeazs. <br />6~ 1 <br /> <br />
