Methods In addition to hydraulic design criteria defined by Bondurant and Kemper (1985), our prototype "fish screen" design incorporated a circular outer wall with an attached fish bypass pipe (Figure 54), along with inflow and outflow capacity designed to maintain constant flow through the bypass pipe. The screen was designed for a maximum inflow of m s, of which a maximum m^s was available for outflow, with the remainder available for the bypass. The screen incorporated a mm mesh over a m circular stainless screen set at a one percent slope, with a maximum mean approach velocity of meters-per-second over the surface of the screen. We also reduced the screen diameter from the recommended original criteria of 213 cm to 152 cm in order to more effectively wash fish and debris off the screen. Following construction, we 87.
