Starting in the 1920s, gravel mining was active in the city of Maple Grove area in Minnesota. Several gravel pits were produced, and as gravel extraction was winding down, the pits filled with groundwater. Those lakes are now surrounded by residential and commercial development.
One of the gravel pits, called North Arbor Lake, is 16 acres in area and is 40 feet deep. There are no records of Minnesota DNR fish stocking, but the word on the street is that folks may have stocked trout and walleyes in the past. Today, there is plenty of evidence that fish can survive in the lake.
