- Abstract:
- In 2000, the five downstream weirs in the transition pool at Lower Granite Dam were modified so that a 0.3 m (1ft) head could be maintained at each weir to increase velocities through submerged orifices. We hypothesized that with higher flows through the underwater orifices, fish would more readily locate the submerged orifices and move into the ladder without delay. A framework for vertical panels was added, allowing for the addition of panels as needed to reduce the width of the overflow section.
