Lamberton Lake is a 28.5-acre (115,000 m2) freshwater lake located in Kent County in Western Michigan. The lake is approximately 1,700 feet (520 m) long and 1,040 feet (320 m) wide and is centered at just within the city limits in northeast Grand Rapids. The surface elevation is 650 feet (200 m), and most of the lake is less than 15 feet (4.6 m) deep.
Lamberton Lake is fed by Lamberton Creek, which flows from Emerald Lake to Lamberton Lake, entering the lake at the northeast. Two springs also feed the lake. Lamberton Lake discharges into Lamberton Creek at the southeast. Lamberton Creek flows south, then turns west and eventually flows into the Grand River.
The 24 acre Lamberton Lake Fen Nature Preserve, one of 13 nature preserves owned and managed by the Land Conservancy of West Michigan, was established in 1994 and is located both to the northwest and southeast of the lake. Lamberton Creek flows through the preserve's southeast parcel.
In the late nineteenth century Lamberton Lake with Lamberton Creek was under consideration as one of a few possible water sources for the growing city of Grand Rapids.
Geology and topography
Most of the lake bottom is composed of marl. The deeper parts are mostly composed of pulpy peat. There is one island in the lake, approximately 160 feet (49 m) long and 70 feet (21 m) wide, located in the northwest part of the lake. A low ridge runs along the east side of the lake and overlooks it.
