1 Sediment & Physical Parameters Levi Dawes Richard Yang Paul Schiller Paul Burke

2 Outline Quick background What we did (Methods and Results) Conclusions and Suggestions

3 Background North of Potlatch and owned by Larry & Lael Turnbow Dug out 3 years ago, added depth and size High turbidity Ground water inflow Bass and rainbow trout present

14 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

15 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

16 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

17 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

18 Summary Turnbow Pond has high turbidity Our results suggest high clay input Treat with riparian buffer zone and hay
