Located near Mercer in Iron County, Lake of the Falls covers 338 acres and is 23 feet deep at its deepest point. Fish include musky, panfish, largemouth bass, smallmouth bass, northern pike and walleye.  Eagles, loons and numerous other waterfowl, frogs, turtles, and deer are common here.  We often see otters, beaver, muskrats, and lots of other small mammals, and sometimes  bears, wolves, and even, on rare occasions, moose. On many days the loudest sound is the wind in the trees, and most nights the sky is full of stars.

Citizen Lake Monitoring reports, showing results for water clarity and water temperature, done by volunteers from 2003-2007 and 2016-2022 for Lake of the Falls and First Black Lake, can be seen here, along with links to an Interpretive Guide and reports from other area lakes for comparison.

We joined the Wisconsin Mussel Monitoring Project in 2020-21 and spent several happy days waist-deep in the water finding and identifying clams with fun names like Wabash Pigtoe, Fatmucket, and Spike. See our observations page on iNaturalist here.

Acoustic bat monitoring reports, done three times each season, have been removed from the website but are available on LOFA’s Facebook page.
