Our analysis of water levels did not begin until mid-June <br />and our data is used along with data from Figure 10 to estimate <br />water elevations at Old Charlie and Wyasket Lake in mid to late <br />summer. From mid-June through September the Green River and Old <br />Charlie dropped very similarly. However, Wyasket Lake dropped <br />very slowly and it appears that it may retain water through the <br />winter of 1993-1994. This indicates that in their natural <br />condition these bottoms can hold water for very long periods of <br />time following the retreat of flood waters. A year with flooding <br />for long duration, say 4 to 6 weeks, followed by continued high <br />flows of say 10,000 cfs for another 2 to 4 weeks would most <br />likely keep water levels in the bottoms high enough to allow them <br />to go through the winter nearly full. Under these conditions <br />they would not freeze to the bottom, and most likely would <br />contain sufficient oxygen to keep fish alive. <br />17 <br />
