Golden Lake Project Water Quality Improvement Project

2019 marked the completion of a large scale water quality improvement project designed to removed excess nutrients form stormwater prior to it discharging into Golden Lake. Golden Lake is located in the City of Circle Pines and has been designated as being impaired by nutrient contamination. Excess nutrients lead to high algae growth and low water clarity. This project was completed by a partnership of the City of Circle Pines ($70,000) and the Anoka Conservation District ($12,000) with financial contributions from the Rice Creek Watershed ($50,000) District and the Clean Water Fund of the Clean Water Land and Legacy Amendment ($467,968)

Although it looks like little more than a sand volley ball court, the project relies on precise chemistry and physics. The project pumps water from a stormwater pond just upstream of Golden Lake and directs that water through a sand filter that is enhanced with iron filings. The iron filings chemically bind to the nutrient pollution. The clean, filtered water discharges to an old ditch alignment that goes to Golden Lake. When functioning per the design, the project should remove 40-60 pounds per year of phosphorus for 25 years, which gets us 50% of the way to our goal for Golden Lake.

Landscaping for Wildlife

This may not seem like the time of year to be planning for habitat improvements on your property, but if you want to take advantage of good prices on bare root trees and shrubs, now is the time to order. Anoka Conservation District's annual tree sale is a great place to start.

When asked by property owners what they can do to attract wildlife to their property, I start with the basic; 1) minimize mowing, and 2) provide food, water, shelter, and plenty of space.


Food: Flowers, fruit, buds, twigs, seeds, nectar, and foliage are food for many of our local birds, insects, and small mammals. These little critters are in turn, food for larger animals. If you build from the bottom up, and create habitat for the smallest creatures, the larger ones will follow and your habitat will be more stable. Planting trees, shrubs, flowering plants, and grasses will all get you heading in the right direction. Use native species to ensure they attract wildlife from this area.

Water: If you have a natural water source, like a pond, wetland, lake or river, you are all set. Flowing water attracts the most wildlife, but still water works well too. If you plan to add an artificial water source, everything from a simple bird bath to a fancy water feature like a lined pond with flowing water and pump, will bring in everything from birds and butterflies, to frogs and deer.


Shelter: Shelter comes in natural and manufactured forms. Bird and bat houses are options, as are wood or rock piles. Consider leaving fallen trees to lay on the ground or dead standing trees to remain, if they aren't a safety concern. Plant trees and shrubs for nesting. Even tall native grasses provide good cover for deer and birds to bed down in.

Space: Animals have varied needs in terms of space. Some defend large areas while others live in harmony with close neighbors. Whether or not you have a small urban oasis or 40 acres of wild open space, if you provide food, water, and shelter, it will attract wildlife to fill the available space. Curb your expectations to the limits of your property and do a little research on any particular species you are hoping to draw in.

Some landscape features you may want to consider:

  • butterfly gardens
  • frog ponds
  • native prairie gardens
  • shrub groves
  • rock or brush piles
  • bird baths
  • feeders
  • pollinator garden
  • hummingbird garden
