Pentwater
Pentwater Harbor's wave absorbers were completed in May of 2001. Pentwater's
absorbers are on both the north and south jetties placed directly across from
one another. Both are approximately 200 feet long and 30-40 feet wide with
2.5-5 ton armor stone, 1000-1500 lb underlayer stone and 1 to 50 lb bedding
stone. All stone is placed at a 2H:1V slope. They are open to wave interaction
on both the lake and channel sides, with a concrete walkway in the middle
supported by H-piles. The predominant wave direction, in deep water, for
Pentwater is out of the south-southwest. A detailed study including physical
and numerical modeling is currently underway for this harbor. The response from
the local residents has been positive concerning the effectiveness of the wave
absorber cells. The project depth is 16 feet.
