July 10, 2014: Six River Watchers completed the tour of the Edwards Aquifer with a canoe trip to Cold Springs. This summer River Watchers have tested water upstream of the Recharge Zone, which extends from Kyle to south Austin, they crawled through Whirlpool Cave Preserve, which is an occasional floodwater route with over 400 m of total passage, swam at Barton Springs, tested below the outfall of Barton Springs Swimming Pool, and then canoed to Cold Springs. Thanks again to Zilker Park Boat Rentals for making this opportunity happen. We ended a great adventure day with lunch at Sandy’s.
