largest capital improvements projects, the Painter Creek and the Gleason Lake Creek projects, address two of the largest sources of phosphorus. The Long Lake project will focus on another large phosphorus source. Two future proposed capital improvement projects will look at Langdon Lake and Six Mile Creek. 1 Lake Miimetoiilui Total Phosphorus Loadings 1 Tributary Average Annual Loading (tons/yr) Gleason Lake Creek 1.06 Long Lake Creek 0.35 1 Painter Creek 3.78 1 Six Mile Creek 0.72 1 Minnewashta Creek 0.06 1 Langdon Lake Outlet 1.10 Christmas Lake Creek 0.02 1 The District’s Gleason Creek, Painter Creek and the Headwaters Control Structure capital improvements projects cut flooding around Lake Minnetonka.
