If you use the cut on the river verses going out of the mouth to the lake, there are 2 barges under water,
with rerod and wood posts on them.
As you come out between the open area in the breakwall going out to the lake, they are on your port side.(towards the island/old garwoods location)
They are aprox. 50-100 yrds off the to the left, aprox 50 yrds from shore i believe (aprox.) can't remeber exact location hence approx. but they are there, used to get marked with milk jugs each year.
Closer to garwoods old location, there is a huge rock just under the water, should be visible with the low water.
