Lake Catherine is small enough to tempt an angler into fishing it entirely from the shoreline inward. Its depth suggests a different approach. Approximately 155 acres of surface water sit above a basin reaching about 45 feet, so there is room for fish to occupy levels that a fast bank-fishing circuit never touches.
This is a place where I would spend time looking before spending time casting. Not necessarily a long time: a short pass across a promising area can tell you whether bait and fish are near the bank, along a slope or suspended farther out.
The deepest reading is not a fishing instruction
Depth on a map describes the bottom. It does not describe the location of food or the combination of temperature and oxygen available to fish on your visit. Dropping a lure to the deepest hole without other evidence can leave you fishing beneath everything worth catching.
Watch for suspended bait and repeatable groups of fish. A small swimbait retrieved through their level may be a better test than a bottom rig. If you have no electronics, use consistent casts and counted falls to sample a few levels without pretending you know exactly where the fish are.
What the species list does—and does not—tell you
Walleye, Muskellunge, Northern Pike, Largemouth Bass, Smallmouth Bass, Black Crappie, White Crappie, Bluegill, Yellow Perch, Pumpkinseed Sunfish, Channel Catfish, Flathead Catfish, Yellow Bass, White Bass, Common Carp, Freshwater Drum, Gizzard Shad, Bowfin, Yellow Bullhead, Black Bullhead, White Sucker, Warmouth, Green Sunfish, Mimic Shiner, and Cisco.
Cisco is worth noticing because it gives this list a different character from many nearby waters. It is not, by itself, evidence of an abundant or easily caught population. I would not plan a trip around a guaranteed cisco catch. A species record and a current fishing forecast answer different questions.
The same distinction applies to small forage fish. Mimic shiners and gizzard shad help describe the community, but they should not be presented as equivalent angling targets alongside bass or crappie.
Three useful depth choices
Near cover
Largemouth bass and sunfish provide reasons to start around available vegetation or shaded structure. A compact jig or lightly weighted plastic lets you fish the feature slowly enough to examine it. Avoid landing every cast directly on top of the place you expect a fish to hold.
On a bottom change
For walleye, smallmouth bass or perch, a firm patch or a change in slope may be more useful than the visible bank. Work across it to search and along it once a bite identifies the level. Adjust lure weight so you can feel what is happening without dragging continuously.
Above deeper water
Crappie and other fish can suspend. A bait held slightly above them is worth trying before one that sinks through and away from the school. Short pauses and a slow fall let you observe whether they want movement or time to inspect the lure.

Planning a deliberate outing
I would bring a light jig setup and another rod suited to the intended larger target. If that target is pike or muskellunge, the leader and landing equipment need to suit it before the trip starts.
Warm-weather fishing makes the distinction between bottom depth and fish depth especially important. I would compare a shallower feeding opportunity with bait suspended outside it, instead of assuming the whole basin is equally usable. During a colder visit, the same measured search can work with a slower presentation. Give fish longer to inspect the lure at the level where you have located them.
Arrange established access and study the northern Chain route you intend to use. Residential shoreline is not a substitute for a confirmed place to launch or fish.
Questions about fishing Catherine
Is a fish finder essential?
It is helpful for separating bottom depth from fish depth, but controlled casts and counted lure falls also let you compare levels methodically.
Why might a heavy jig produce fewer bites?
It may fall below suspended fish too quickly. Weight should help the presentation, not simply get the bait to bottom as fast as possible.
