Here is a copy of a email sent to us from our house boat maintenance company.
"Lake Powell Marine just received information, verified by the National Park Service, that they will be opening (blasting) the cut at Castle Rock! To reduce the use of fossil fuel and facilitate uplake traffic the cut will be reduced to a depth of 3600 ft. This action should allow all boat traffic to traverse this area throughout the season!!
Scheduled to be completed by April 2008!"
