I participated in a redd survey on a small coastal river on Saturday. We counted 51 redds and spotted 20 big steelhead. On of my duties included marking redds. We used hot pink tape tied around a rock or weighted object. I marked one redd, as the maker sunk to the bottom and enormous buck aggressively swam up and checked out my fluttering marker only to return to his holding water. What a rush as from above it appeared as he almost tracked the marker through the air.
