Moore Lake: A trip through time

Moore Lake: A trip through time. . , 1938 , In 1938, Moore Lake was surrounded by farms and forests and very few people. Despite the lack of modern development, Moore Lake still had its problems. Runoff from agricultural fields carrying sediment and nutrients appears to have negatively impacted water quality. While nutrients are needed for healthy plant growth, in excess they cause algae blooms like the one seen on Moore Lake in this photo., 1964 , By 1964, the population grew substantially in the Twin Cities metropolitan area generating a need for more homes, roads and schools. Agricultural land was taken out of production, wetlands were filled and forests were logged to make space for these changes. Students lined the halls of Fridley Middle School and construction of Interstate 694 was underway. What other differences do you see? Take a closer look at Moore Lake., 2012 , In 2012, development continues, but at a slower pace because vacant land has become limited. Impervious surfaces such as buildings, roads and driveways not dominate the landscape. This had led to a decrease in natural filters such as forests and wetlands around Moore Lake and an increase in stormwater runoff and local flooding. How do you think these changes have impacted water quality?
