Fish Passage Enhancement to El Jaro Creek at Rancho San Julian

Fish Passage Enhancement to El Jaro Creek at Rancho San Julian

The proposed project will modify the left streambank and channel (facing upstream) across the grade control structure below the bridge entrance to Rancho San Julian, El Jaro Creek. The concrete apron currently prevents access for migrating steelhead during low/moderate flows. The project includes demolition of a portion of the existing concrete sill and the construction of a concrete fishway composed of nine pools, each 4 feet wide by 6 feet long and 2.5 feet deep, to provide no more than an 8 inch vertical jump at each pool. Pool construction will involve excavating approx. 4-5 cubic yards of concrete and bedrock and placing approx. 3-4 cubic yards of concrete. The excavation will be performed using hard tools and a pneumatic jackhammer.
