This structure was designed specifically to handle debris, as the water at the point of diversion has already been screened for fish.
In October of 2010, FID installed a custom farmers screen just upstream of the fore bay of their penstock in order to manage debris that accumulates in their conveyance canal.
This water has already been screened for fish at the point of diversion so this structure was designed specifically to handle debris.
By-pass flows are recaptured and sent to the fore bay while screened debris is removed periodically from the system. Typically, about 75 CFS is run through this debris screen but volume can fluctuate depending on the time of year. This debris screen system includes improved emergency by-pass functions to reduce District liability due to canal failures.
