Connie Demoyer (Svoboda), Tracy Vermeyen. 2009. "Durango Pumping Plant Fish Screens Field Evaluation". Bureau of Reclamation, Report Number PAP-991.

Abstract: The objective of this field evaluation was to examine the hydraulic performance of the fish screening structure for the given operating condition. The evaluation included an assessment of velocity magnitudes and uniformity at the screen face and debris accumulation in the screening facility. All vertical louvers behind the fish screens were initially set by field personnel to 10% open as recommended by the mechanical design team. In the field evaluation, the vertical louvers were adjusted to optimize approach velocity uniformity along the screen face. The evaluation was conducted shortly after the maximum pumping rate of 280 ft3/s was reached during the initial filling of the reservoir in June 2009.
