SHERIDAN, Colo. (CBS4)– The water levels in the South Platte River were lower on Tuesday thanks to the Army Corps of Engineers who slowed the release of water from Chatfield Reservoir.

They slowed the release of water in hopes of helping search crews find Joe Goodwin who went missing on Saturday afternoon after went tubing in the South Platte River.

Goodwin, 20, from Littleton, was on a tubing trip with three others when he went missing.

Search crews of about 12 divers resumed their search at 8 a.m. Tuesday along the river from West Union Avenue to West Hamilton.

Goodwin is a member of the Marine Corps Reserve.

Denver Dive Captain Troy Morelli told CBS4 that despite their efforts over the past couple of days, the water has been so high it’s prevented them from searching as thoroughly as they would like.

Crews wrapped up their search at noon Tuesday after their efforts did not produce any signs of Goodwin.

Restrictions have been put in place on the South Platte River and Boulder Creek. Jefferson and Douglas Counties have also closed waterways to inflatable devices.
