Como Lake


District residents need no introduction to Como Lake and its parkland, a popular spot for recreation in the City of Saint Paul. The lake drains more than 1,711 acres of land in Saint Paul, Roseville, and Falcon Heights. Como Lake draws more than 4.3 million visitors each year for outdoor activities, including Como Regional Park and Golf Course and the lake’s surrounding attractions. With a maximum depth of 15.5 feet, Como Lake is a shallow body of water. The shallow depth of the lake, coupled with large nutrient inputs from upland areas, has had a significant impact on Como Lake water quality. In fact, CRWD began when a group of residents raised concerns about the water quality in Como Lake. Accordingly, the District has placed a high priority on improving Como Lake, as it is one of the most recognizable and well-loved water resources.

Como Lake Health

Unfortunately, stormwater runoff from the lake’s urban surroundings has hurt its water quality. In addition to nutrient pollution, sediment and high algae growth in the summer have changed Como Lake’s natural balance. Historically, sediment from construction, roads and general erosion has been a significant water quality challenge for the lake, reducing overall lake volume and decreasing habitat value for the lake’s fish populations. However, Como Lake’s greatest water quality problem is excessive phosphorus, which has caused annual algal blooms and overgrowth that has further damaged the integrity of the lake.
