Dove Rosario twice on 2 Aug, both at low tide. Visibility on both dives was about 5'. We went around Urchin Rock on both dives. Tons and tons of different kinds of algae along with seaweed. There were spots 3' deep. Never saw any oto but there was plenty of proof that they were there. Lost of sea cucumbers and yellow rock fish. Easy entry but the climb up to car required a break before the hill. Got a refill of air in Anacortes...and did two more on Sunday. Not much changed from the 2nd.
