The cache is not at the stated coordinates but those coordinates
are where you start. From there, take a bearing of 182 degrees.
Okay, anywhere in the 180-185 degree range should do the trick. You
should see an obvious location for the cache. No, it is not under
water.
Once you get there, you will need to use the hint but as of today
that narrows it down to two possible locations.
PLEASE, PLEASE cover it back up well so it's not a victim of
muggles.
I'm suggesting this does NOT be done in the winter or early spring
as you might have to contend with thin ice. That would not be
smart.
Have fun!
