[Sonar] Lake Minnetonka water level

[J.R.]

FYI link below If you want to follow the lake level
928.15 was the lowest level I have seen this year.
928.20 was a level that J24s have been able to get in and out at and Sonars
are
928.25 was the level that Capri 25 Code Blue pulled out at and they had 3
people on when they went to the crane
(** The above information is based of my in person observations)

In theory .. A Sonar should be good to a lake level of just under
928.00....
Based on Code Blue Draft that is 3.4" greater than a Sonar...
(At that level you might be pushing some mud ;)
(3.4" = .283ft ... code blue pulled at 928.25-.283 = 927.967 lake level for
a sonar equivalent)

*Drafts*
3'9.6" j22
3'11.0" Sonar
4'0.0" j24
4'2.4" Capri 25
