Lake of the Week: Diamond Lake
This beautiful, glacially formed, 153-acre lake is located in northeastern Lake County, within the Village of Mundelein. Diamond Lake is home to the popular Diamond Lake Beach and Recreation Center, which offers a sandy beach, grassy areas, and shaded picnic grove and is a summertime destination for swimming, boating, fishing, boat rentals and special events — like the zany Cardboard Regatta, which will be held this year on August 6.
In the 1800’s to early 1900’s, before electric refrigerators, Diamond Lake was the source of ice for the numerous icehouses that supplied nearby Libertyville.
Diamond Lake has a maximum depth of 23 feet and an average depth of 7 feet. There’s one boat ramp open to the public, and a fee is required. You’ll find great fish here, including catfish, northern pike, muskie, sunfish, yellow perch, bluegill and yellow bass. It’s line fishing only with a two-pole limit.
