Abstract:
The list is of Montana streams that support important fisheries or contribute to important fisheries (i.e., provide spawning and rearing habitats) that are significantly dewatered by man-caused flow depletions. Most man-made dewatering occurs during the irrigation season (July-September). Although most dewatering is caused by irrigation withdrawals, a few of the listed waters are dewatered through dam manipulations for both agricultural use and power production.
Purpose:
To provide a spatial representation of documented chronically or periodically dewatered streams in Montana.
