Summary Information
Fish Passability 0.9
Fish Passage is an area of concern for this site.
Yes, the water is being held up by a mud dam against the trash rack so that water isn't flowing through and the water level is elevated on that side.
A future visit to this site is recommended. The water flow is blocked.
