摘要：本文描述了一种快速简便的方法来确定流量，以保护温水和冷水中的水生资源，基于它们的平均流量。生物学家借助美国地质调查局（USGS）提供的水文数据进行分析。1964年至1974年间，对3个州的11条河流进行了详细的实地研究，以测试“蒙大拿方法”。这项工作包括对196英里的58个断面的38种不同水流进行物理、化学和生物分析，这些水流对冷水和温水渔业都有影响。这些研究都是在国家渔业生物学家的帮助下计划、实施和分析的，结果表明，在大多数平均流量相同的河流上，水生栖息地的条件非常相似。在过去的17年里，在21个不同的州，对美国地质勘探局测量点附近的数百个额外的水流形态进行了类似的分析，证实了这种相关性在各种各样的河流中都存在。百分之十的平均…
Abstract A quick, easy methodology is described for determining flows to protect the aquatic resources in both warmwater and coldwater streams, based on their average flow. Biologists do their analysis with aid of hydrological data provided by the U.S. Geological Survey (USGS). Detailed field studies were conducted on 11 streams in 3 states between 1964 and 1974, testing the “Montana Method.” This work involved physical, chemical, and biological analyses of 38 different flows at 58 cross-sections on 196 stream-miles, affecting both coldwater and warmwater fisheries. The studies, all planned, conducted, and analyzed with the help of state fisheries biologists, reveal that the condition of the aquatic habitat is remarkably similar on most of the streams carrying the same portion of the average flow. Similar analyses of hundreds of additional flow regimens near USGS gages in 21 different states during the past 17 years substantiated this correlation on a wide variety of streams. Ten percent of the average fl...
