Secchi Depth LocationDuplicate NumberSecchi Depth (m)Photic Zone Depth (m) A B C Average
Pond Bottom Low organic matter suggests large amounts of clay Pond will not leak, however it is not good for aquatic vegetation Adding more aquatic vegetation will eventually increase organic matter
Suggestions (long term) Plant more riparian and bank vegetation, especially shrubs Increased root length and size will stabilize soil and lower turbidity Increased plant diversity will lead to increased aquatic animal diversity
Suggestions (short term) Apply calcium sulfate (CaSO 4 ) (gypsum) CaSO 4 binds to clay particles May alter water chemistry Negative charges repel each other Cations bind to clay and make it neutral
Suggestions (short term) Add alfalfa to shallow areas 2 square bales/acre of surface area in spring and summer Decomposition => positively charged molecules Adds food for microbes and bugs Decomposition consumes O2
Summary Turnbow Pond has high turbidity Our results suggest high clay input Treat with riparian buffer zone and hay
