Welcome back to the lake! Wayne has some great links to help you know when it is okay to launch at Hite.
First is a link called "launch ramps." Here:
http://wayneswords.com/index.php?option=com_content&view=section&layout=blog&id=6&Itemid=12 If you scroll down to Hite and look there, the last update was in December 2016 when you would have had a rough time launching at Powell. But not to worry, the link has more useful information, like where it says "If elevation is above 3611 then it is likely that a launch at some location along the shoreline is possible. If less than 3611 then go to Bullfrog or Halls and run uplake." It goes on to give you tips on the best places to launch for different lake levels.
About this time, you are probably wondering, what is the lake level? Not to worry, Wayne has a second link for that. Here:
http://lakepowell.water-data.com/ If you follow that link, it says that the current lake level (as of yesterday) was 3628.74. As much as that high lake level is good for the world (at least those who need to drink water) it probably saddens Glen Canyon Institute. But it will give you and me a warm fuzzy feeling.
Third, you are doing the right thing to check in here. This time of year at high runoff, you might be launching into water that is the consistency of chocolate pudding. That will probably get better by the time of your trip, but you will want to check back to be sure. Chances are, someone will be able to give you a recent report.
Again, Welcome back!
