It is stated on pages 9 and 87 of the Geological SUI'vey <br />report (1975): <br /> <br />"The survival of the wet-meadow complex adjacent to the Platte <br /> <br />River in central Nebraska probably is dependent on relatively <br /> <br />high river stages during the winter and early spring. The <br /> <br />probable hydrologic factors that affect the ecologic health <br /> <br />of the wet-meadow complex include high stream <<tages that <br /><,. '\ <br />result in a high water table during the Ja~ii,tY-~il pericid.) <br /> <br />The high water levels during this periPd<:p'roVi~ for healthy , ~ <br />(.. ", \.

Therefore, the <br />wet-meadow complex should be maintained." <br /> <br />On the other hand, the Fish and Wildlife Service believes that cumulative <br /> <br />surface flow depletions from planned and proposed water resource develop- <br /> <br /> <br />ment projects could cause dessication and eventual loss of most of the <br /> <br /> <br />Platte's wet meadow habitat. <br /> <br />q <br /> <br />, <br />
