The last two weeks of June were hot, dry, <br /> and windy,and irrigators shifted into high hear. There is still YAMPA RIVER AT STEAMBOAT <br /> sufficient water in the rivers to meet irrigation demands. saD FLDW 8Y wATEa Yr�w <br /> There were some calls in isolated areas, mostly on the small <br /> side tributaries. Ranchers were cutting some hay by the end SOO <br /> of the month. <br /> +00 <br /> Outlook <br /> Stream flows will continue to drop until reaching base 300 <br /> ti- <br /> flows later in July. There should be sufficient water for the ISv 200 <br /> first hay crop, and possibly enough in some areas for a second 1 <br /> cutting. The dry land hay crop appears to be the best in 1UD <br /> several years. <br /> 0 <br /> Oct Nov Doc Jan Feb March Aar I May June July Aug Sect <br /> Administrative/Management Concerns MONTH <br /> 4 WET(198+) O WY(4977) A AVG X 1997 <br /> There are no administrative or management concerns <br /> anticipated. <br /> Public Use Impacts <br /> There are no adverse public use impacts anticipated. <br /> 8 <br />
