Here is something I recently read: "Canadian Geese in flight can be majestic, grand, and inspiring. It’s when they get down on land that another problem appears… goose poop. Waterfowl, according to some studies, can produce 25% to 34% of the total phosphorous budget in a watershed. And phosphorous is what we need to control around the Three Lakes in order to control weeds and algae." "Left unchecked, their population will double every 5 years. While feeding, geese defecate every 7 minutes. Each goose produces 1 to 3 pounds of waste per day. In addition to phosphorous, they contribute pathogens such as e coli and the bacteria that cause swimmer’s itch, as well as giardia, cryptosporidium, and campylobacter. Geese are one vector for the spread of invasive plants such as milfoil and water chestnut." Now if we could just get rid of all the non migratory geese, ban use of fertilizer use on watershed areas as well as drainage our only problem would be low water!
