Physical and Hydraulic Monitoring on the Yellowstone River Fish Bypass Channel, Montana, May 2022 to August 2023

This data release was produced by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation to present the results of monitoring efforts on the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish with a route around a diversion dam. The objective of this study is to monitor the physical and hydraulic characteristics of the bypass channel, including flow split, minimum depth for the deepest continuous 30 cross sectional feet, and mean channel velocity, which are summarized in the data files in this data release. Physical and hydraulic data collected during this study will be used to ensure that the hydraulic design criteria of the bypass channel are being met.

本数据集由美国地质调查局（U.S. Geological Survey, USGS）与美国垦务局（Bureau of Reclamation）合作编制，旨在依据《下黄石河适应性管理与监测计划》的规范，发布黄石河鱼类绕行通道的监测工作成果。该鱼类绕行通道的建造目的是为洄游至上游的鱼类提供绕过分水坝的通行路径。本研究的目标为监测绕行通道的物理与水力特性，包括分流比、连续30断面英尺段最深区域的最小水深以及通道平均流速，相关参数已汇总于本数据集的数据文件中。本研究采集的物理与水力数据将用于验证绕行通道是否符合其水力设计标准。
