Waterfall Effects on Native and Non-Native Fish Movement in the San Juan River

Learn about the ecological impacts of a waterfall barrier on fish migration in the San Juan River through this informative presentation from the Bureau of Reclamation. Explore how the 2001 waterfall formation near Lake Powell in Utah created obstacles for upstream fish movement, particularly affecting the Razorback Sucker (Xyrauchen texanus) population. Examine the conservation efforts implemented since 2016, including the spring capture and transport program that moves fish beyond the barrier. Gain insights into similar geographical barriers, their formation processes, and the broader implications for managing both native and non-native fish species as part of Reclamation's environmental compliance initiatives. Delivered by Mark McKinstry, this hour-long talk provides valuable understanding of aquatic ecosystem management and conservation strategies in the face of natural barriers.
