SUMMARY OF VOLUNTEER SURVEY

WATER QUALITY-----------------------------------------------------------------------
Overall water quality was good.  The worst problems were reported as: 
     1. suspended sediment   2. excessive aquatic plants   3. decaying vegetation
Sources of actual or potential problems includes: 
     Unknown
Were there days (and how many) when poor water quality impaired
      Fishing - NO(0)        Swimming - NO(0)        Aesthetics - NO(0) 
MANAGEMENT--------------------------------------------------------------------------
Did the lake receive chemical treatments this year?                YES
Were fish stocked this year?                                       YES
Any lake groups present (such as a lake association)?              NO
Any lake management activities this year?                          NO
OTHER-------------------------------------------------------------------------------
How many homes/new homes are there on the lake shore? 0              
Changes since last year? The lake was up 23" in the spring compared to last year.
