Finding Data
        Water Quality Cont’d
• Data do not always reflect observations
• 1960’s
  – Algae blooms
• 1972 Clean Water Act
  – Direct discharge (waste water treatment
    facilities) pollution targeted
     • Industrial facilities, Governments, Municipalities,
       some Agricultural facilities
• 1980’s/1990’s
  – Urban and rural runoff targeted
     The Role of Aquatic Plants
• Absorb wind/wave energy
• Maintain Clear water
• Oxygen production
• Habitat
  – Fish/other aquatic life
  – Wildlife
• Nutrient absorption
    Submerged Aquatic Plants Typically
          Become Established
• Plants require
                    May - June
  sufficient sunlight in
  early growth phases
• Occurs at depths of
  lake where light
  supports
  photosynthesis
• Turbidity can prevent
  light reaching aquatic
  plants
     Recreational Response
• “Bad for swimming and boating.”
• “Cancellation of backyard activities.”
• “Loss of revenue from anglers and
  other recreational users.”
• “Bad for tourism.”
           Fishery Response
• Numerous reports state this is the best
  fishing (bluegills and perch) that people
  can remember
• Lake-wide Fishery Assessments
  – Perch, bluegill and crappie numbers on the rise
     • Near shore areas
        – Spawning, refuge, feeding
     • Increase in fish numbers coincides with increased
       water clarity and the increase in rooted aquatic
       vegetation.
         Fishery Response
• The total impact to the local
  economy is:

• $234,000,000 annually
    • Supports 4,300 jobs
         Wildlife Response
Best waterfowl hunting in many years
    • Increase in migratory waterfowl numbers
      coincides with increased water clarity and
      the increase in rooted aquatic vegetation.
    Our Mission and Challenge
• To manage the system in a manner that
  considers all of our beneficial uses so we all may
  enjoy this great resource.
   – Short-term
      • Aquatic plant management and APM permits
   – Long-term
      • Lake and aquatic plant management

         – Grant Program
 Aquatic Plant Management and
      Protection Program
• Manual Removal

• Mechanical Harvesting (NR 109
  Permit)
Aquatic Plant Manual Removal
• Waterfront
  Landowner may cut,
  rake, and remove
  aquatic plants in a
  30’ area without a
  permit.
• Cannot use external
  or auxiliary power:
  must be a hand-held
  device.
• Vegetation must be
  removed from the
  water body.
