Typical pool and riffle cross-sections and width to depth ratio <br /> <br />t,,,", <br />....;( for each. <br />tv <br />(.0 <br /> <br />c. Monthly discharges for two or more series, e.g., median and dry <br /> <br />years. <br /> <br />C. Target Fish Species and Life Stages <br /> <br />Target species are those which are expected to respond significantly to <br /> <br /> <br />imposed physical changes in their aquatic environment. The methodology <br /> <br /> <br />paper(1) previously cited contains suggested target species. "Pool <br /> <br />. <br /> <br />species" and "riffle species" are listed for evaluation of the impacts on <br /> <br />both types of habitat. Species listed may be combined as appropriate for <br />small streams or the larger rivers. <br /> <br />Fish may be affected by changes in the stream environment during any of <br /> <br /> <br />four life history stages: egg (spawning and incubation), fry, juvenile, <br /> <br /> <br />or adult. Passage is a critical activity which must be considered in the <br /> <br /> <br />life cycl~s of certain fishes. <br /> <br />D.
