Patent ID: 7594779

Claim:
A fish-safe water diversion apparatus, comprising: an input, a non-diverted output and a diverted output; a screen generally disposed in a configuration that is more horizontal than vertical and configured in said apparatus such that water entering said input flows substantially under said screen to said non-diverted output and substantially upwardly through said screen to said diverted output; and an under screen passage chamber is defined on a lower portion thereof by a bottom and a surface ascending from the bottom, a downstream portion of the ascending surface being configured to convey fluid thereover to the non-diverted output and the point at which fluid is conveyed over the downstream portion of the ascending surface into the non-diverted output being above the bottom so as to create a survival pool over the bottom that is of sufficient depth to create a condition favorable to survival of juvenile salmonids; wherein the path of water from said input through said under screen passage chamber to said non-diverted output is substantially unimpeded for unobstructed movement of fish from the input to the non-diverted output.
