2	About Lakes Lakes reflect their watersheds (soils, vegetation, land uses) and climates Morphometry (shape, depth, size) and hydrology (flushing rate) are important determinants of how lakes function Lakes are very patchy - they are not homogeneous well-stirred bathtubs as they often appear to be - they exhibit great variability which creates large and small habitats
3	3 main factors determine a lake’s trophic state Watershed, climate & morphometry Rate of nutrient supply (from watershed & airshed) Bedrock geology, soils, vegetation, land uses, atmospheric deposition Climate Sunlight, temperature, precipitation and hydrology Morphometry Depth (mean and max), size (volume/area), “roundness” (shoreline convolutions)

19	Eurasian Water-milfoil Introduced to US in 1940s; First found in WI in 1960s Currently found in more than 400 inland lakes Forms dense mats - interferes with water recreation Displaces native vegetation
20	Eurasian Water-milfoil Spread Spread via fragmentation Develop adventitious roots Small plant fragment can grow into new plant (why harvesting does not work)
21	Curly-leaf Pondweed Accidentally introduced to US with common carp (late 1800s) Fairly widespread Active very early in growing season – even under ice Can form dense mats, interfering with recreation and native plants
22	Purple Loosestrife Brought from Europe as garden plant (late 1800s) Crowd out native wetland species Little food/habitat value Produce > 1 million seeds annually
23	Blanket Weed This is actually more of an algae than a weed however, it can cover an entire cove as seen here.
24	Weed Problem Creating depth reduces algae Less algae means less chemicals needed ($$) to treat the lake Less chemicals means improved water quality Money saved on chemical treatments could be used elsewhere
25	Future Threats? Losing more acreage to wetlands Losing property value Losing members LOSING THE LAKE!
26	We need to act now while we have an opportunity with this loan and while we have a shot at preventing more of the lake being lost to wetlands.
