Habitat structures were placed a few weeks prior to the survey; however, stream flows were inadequate at that time to cause change to the stream structure in association with the placed habitat structures. Two habitat structure sites (one boulder oval habitat structure and one boulder and log habitat structure) were intentionally targeted to monitor substrate accumulation with cross-section surveys. Poor visibility in pools due to sedimentation from recently placed habitat structures. 2013 REACH: 1 __________ LOCATION: T23S-R06W-S06NW
