Como Lake

Background

District residents need no introduction to Como Lake and its parkland, a popular spot for recreation in the City of Saint Paul. 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. The 70 acre lake drains more than 1,711 acres of land in Saint Paul, Roseville, and Falcon Heights. 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

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.

Como Lake Management Plan

CRWD is committed to improving water quality in Como Lake. In 2002, CRWD created a strategic plan (view 2002 Como Lake Strategic Management Plan) that guided the District and its partners to address Como Lake water quality priorities. In 2017, CRWD conducted the Como Lake Water Quality Drivers Analysis Study to better understand what is causing the lake’s poor water quality. Based on the results of this study and ongoing monitoring, the District created a revised Como Lake Management Plan (CLMP) in 2019 that also includes input from residents and community partners. The revised plan builds on the past two decades of work around the lake with a specific focus on management within the lake. The goals of the CLMP are:

  • Goal 1: Como Lake will be managed as an ecologically healthy, shallow lake.
  • Goal 2: Maintain healthy shoreline areas that can support a variety of wildlife and contribute to the ecological health of Como Lake.
  • Goal 3: Maintain a variety of year-round recreational opportunities that are appropriate for a shallow urban lake
  • Goal 4: Achieve strong sustained community engagement and stewardship to improve and protect Como Lake
  • Goal 5: Utilize the best science, partnerships, and resources to ensure successful implementation of the CLMP over the life of the plan (20 years).

The life of the revised plan is defined as 20 years (2019-2039) to allow enough time for Como Lake to respond to in-lake and watershed management actions and achieve ecological balance. The CLMP is an adaptive management plan and will be updated every few years as short-term actions are implemented and evaluated.
