<br />The April 1st figures were not indicative of an impending snowmelt flood threat in any <br />of the state's major watersheds. Then, approximately midway through April, things changed. <br />The dry and mild weather that had prevailed through much of the winter was replaced by wetter <br />and cooler weather. When the May I, 1995 figures were calculated, there had been a <br />considerable change. In fact, the increase in the basin figures from April I to May I led directly <br />to the creation of the Flood Task Force and subsequently to all of the other preparatory measures <br />taken by federal, state and local agencies and by private entities. <br /> <br />From about the middle of May through the first week in June, the Front Range and <br />adjacent foothills, as well as portions of the Eastern Plains, experienced a lot of rain. In some <br />locations rains were heavy enough to cause localized flooding. <br /> <br />By June I, 1995 the basin figures were quite a bit worse than the figures on May I. <br />As the rains were affecting the lower elevation portions of the state's watersheds, the higher <br />portions of those watersheds were experiencing two problems: I) no melting of the snowpack and <br />2) the addition of more snow. Instead of slowly getting better each day in May and early June, <br />the state's snowpack situation was getting worse each day. For the first and second week in June <br />that trend continued. Almost at the middle of June the weather got hot. During the week <br />following the Task Force's regular Monday meeting on June 12, 1995 stream levels in the <br />mountains rose every day. They peaked on the weekend (June 17-18), partly because Sunday, <br />June 18 was a very cold and rainy day (a record cold day in Grand Junction). After that <br />weekend temperatures were not as hot for about three weeks, so much of the remaining snowpack <br />melted slowly. Stream levels dropped because of this moderate weather. <br /> <br />Then another heat wave arrived after July 4. About July 12 the two watersheds with <br />significant snowpack still remaining, the Roaring Fork River and Clear Creek, experienced peak <br />flows again. After those peaks none of the state's watersheds had enough remaining snowpack <br />combined with hot weather to produce significant flooding. There may have been more unusual <br />weather after that, but it was no longer flood weather. <br /> <br />Basalt, Colorado \\,1uld have experienced a flood exceeding the 100-year event if it hadn't <br />been for the additional storage allocation in Reudi Reservoir. Attentive operational measures <br />provided flood control at Basalt by reducing the flow 1,000 cfs. <br /> <br />
