<br />'I <br /> <br />information at any point on any stream. Simple channel geometry <br />measurements have produced average flow data as accurate as 10 years <br />of continuous gage records.13 The standard errors were lowest for <br />mountain regions and in competition with 5 to 10 years of gaged <br />records for the plains region. There is very little variation when <br />results are compared between channel width and average flow (fig.3). <br />Mean annual discharge is one of the few criteria that will be routinely <br />provided by this future program. Therefore, the Montana Method can <br />still be used with this new program, since it is based primarily on <br />knowledge of the mean annual discharge or average flow. The <br />ability to provide the average flow at any point on any stream <br />would actually facilitate the use of the Montana Method in the <br />future. <br /> <br />Adopting the metric system would not require conversion tables <br />or other problems since this method is based on percentages of <br />the average flow however it is expressed. <br /> <br />CONCLUSIONS <br /> <br />The following conclusions on flows are the result of frequent <br />observations and detailed analyses of flows from a wide variety of <br />streams over a large geographical area of the United States <br /> <br />17 <br />
