2021 June - Aug

June 03, 2021 -- The City Lake Contractor (Solitude Lake Management) had a single boat on the lake, where another "spot-treat" copper algaecide application was likely applied (due to the blue-colored sprayed liquid witnessed) on the lake in certain areas. Total application locations remain unknown and total quantity administered is also unknown.

June 22, 2021 -- The City Lake Contractor (Solitude Lake Management) had a single boat on the lake, where another "spot-treat" copper algaecide application was likely applied (due to the blue-colored sprayed liquid residue and odor) on the lake in certain areas. Total application locations remain unknown and total quantity administered is also unknown. ** This was very limited and haphazard spraying, the boat did not even cruise around to observe large lake sections. The contractor did not even review perimeter or spray in Southeast Lake Lobe despite algae being present in area and cattails, as observed by multiple witnesses. **
