Upstream infiltration should be impossible due to the fact that the overflow pipe sends water out with a 3 foot drop to a rock bed that slows the flow down to the intermittent creek. Any fish swimming upstream would need to travel about a mile from the river into what generally is a dry or nearly dry creek. Then would need to climb the 3 ft. outflow water drop.
