WATER QUALITY IMPACTS ASSOCIATED WITH EUTROPHICATION • Noxious algae (scums, blue-greens, taste and odor, visual) • Excessive macrophyte growth (loss of open water) • Loss of clarity (secchi depth goes down) • Possible loss of macrophytes (via light limitation by algae and periph

• Low dissolved oxygen (loss of habitat for fish and fish food) •

• Low dissolved oxygen (loss of habitat for fish and fish food) • Excessive organic matter production (smothering eggs and bugs) • Blue-green algae inedible by some zooplankton (reduced food chain efficiency) • "Toxic" gases (ammonia, H 2 S) in bottom water (more loss of fish habitat)

• Possible toxins from some species of blue-green algae • Chemical treatment by

• Possible toxins from some species of blue-green algae • Chemical treatment by lakeshore homeowners or managers may result (copper, diquat, 2, 4 -D, etc. ) • Drinking water degradation from treatment disinfection byproducts • Carcinogens, such as chloroform (from increased organic matter reacting with disinfectants like chlorine)
