<br />t <br /> <br />A flow of 2 to 3 times the average flow is often best for kayaks and <br />whitewater canoeing. A flow of this magnitude is also preferable <br />for larger boats with inboard or outboard motors, like those many <br />people use on the annual Missouri and Yellowstone River floats held <br />in June and July in Montana. <br /> <br />. <br /> <br />RECOMMENDATIONS <br /> <br />1. Request "instantaneous flows" to prevent flow releases from dams <br /> <br /> <br />and diversion structures that are averaged over a day, month, or year, <br /> <br /> <br />which permits erratic releases or even no flow at times. <br /> <br />2. Recommend that dual or multiple outlets to all dams be designed <br />and constructed so that minimum flows of an appropriate temperature <br />and quality to protect the aquatic environment can be by-passed at <br />all times, including drawdowns for safety inspections and emergency <br />repairs. <br /> <br />3. Insist that costs for providing of instream flows to protect <br /> <br />the aquatic environment downstream below dams be project costs, <br /> <br />including costs for unforeseen emergency repairs and routine main- <br /> <br />tenance over the life of the project. <br /> <br />, <br />~ <br /> <br />4. Justify only that portion of a stream flow required to fulfill <br />specific instream needs. If fish need a flow of 100 cfs in a segment <br />of stream where there are already legal requirements of 25 cfs for <br />municipal water, l5cfs for irrigation water transpor~ and 10 cfs <br />for a u.s. Environmental Protection Agency water quality requiremen~, <br />you logically and legally should only have to justify a flow of 50 cfs <br /> <br />25 <br />
