Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.

The Lake Pepin Legacy Alliance is a multi-state non-profit organization established in 2009 by an ad hoc committee determined to preserve and restore Lake Pepin as an integral part of the Upper Mississippi River System.
Our Mission
We are dedicated to slowing and reversing the current trend of sediment and nutrient flow to Lake Pepin. We bring a professional approach for public involvement in present and future watershed restoration activities that elevate the importance of implementation of the recommendations and "best practices" that science and reason dictate. Leading with the tools of education and information we will protect the natural heritage of Lake Pepin.
Why We Must Take Action
It is difficult for most of us to visualize the scale of the annual average load of about 1 million metric tons of TSS that burdens the south metro Mississippi river through Lake Pepin. The following may help:
A 40 acre field with dimensions of .25 mile by .25 mile would be loaded with sediment to a height of 28 feet to contain the long-term average annual sediment load of 968,246 MT (metric ton) from all major tributaries to the south metro Mississippi. The Minnesota River contributes 76% of the total, or 21 feet of the sediment. [Over the 20 year period of record for TSS monitoring, this would cover a 23,000 acre watershed, such as 7 Mile Creek north of Mankato, with one foot of sediment.]
To contain the same annual volume of sediment, a downtown Minneapolis city block (330 x 330 feet) would be filled to a height of 454 feet, enough to completely cover the city’s original skyscraper, the 32-story Foshay Tower. The Minnesota River alone accounts for 345 feet. In the past 20 years, 20 such city blocks would have been filled to this height with sediment.
This is based on measured TSS loads and measured sediment densities from Lake Pepin deposits (.7 grams/cubic cm).
Goals
I. To promote a multi-faceted approach to reducing the sediment and
nutrients from upstream tributaries, with emphasis on the Minnesota
River.
Currently, the annual average load is about 1 million mt/year-equivalent to a cubic city
block of sediment. A first objective is to reduce this loading by 50% to achieve
transparency goals supportive of submersed aquatic vegetation targets. This will also
reduce the rate of lake in-filling by one-half, as measured by centimeters (upper and
whole lake) or tonnes (a metric ton or (1000 kg.)
II. To restore and preserve conditions in Upper Pool 4 and the head of
Lake Pepin.
III. To ensure the institutional arrangements for protecting the lake into
the future.
Strategies for Action
Increase public awareness of water quality goals and best land management practices in order to influence the Lake Pepin TMDL to include performance standards for drainage management and design, plus farmland best management practices.
Educate as a means to citizen engagement and behavioral change.
Advocate for implementation of scientifically valid solutions to the water quality problems of our lake.
Provide opportunities for cultural exchanges by continuing upstream- downstream dialogues and communications with farmers and county commissioners. Engage sportsmen, conservationists and others in helping to make restoration happen.
Develop and display an online “local resource management scorecard” to show the public what counties are (and are not) doing to reduce sediment loads into the Mississippi River and Lake Pepin.
Utilize electronic newsletters, the website, and social media to provide current information on all new developments for the general public.
