<br />Unquestionably, the summer rains of 1977 were helpful, but they did not
<br />completely allay the effects of the extremely dry winter which had preceded
<br />them. By October 1977, streamflows in many river basins remained near 50
<br />percent of normal and soil moisture levels in many areas remained low.
<br />Furthermore, the decreased streamwater inflow into reservoirs during the summer
<br />resulted in a reservoir depletion rate which more than doubled that of prior
<br />years. By October, reservoir storage, which had stood at near normal levels the
<br />preceding April, rested at levels 60 percent of normdi. Many reservoirs on the
<br />eastern and western slopes were dry. If the approaching winter season proved to
