I think guys struggle with perch on Higgins do to the clarity of the water. Perch like it dark. On Higgins, light penetrates the water to an average depth of 28ft. On most other Michigan lakes it's 8ft or less so guys are used to catching them shallower. You can nail them on Houghton at 8ft but it's not likely on Higgins, you have to go deeper. If you're catching rock bass and dinks, you are not deep enough.
