3. Sediment/ Organic Material
1. Organic material removed
Less O2 consumption
Water content in the sediment1
Data can be used to estimate water retention characteristics and permeability characteristics.
Important considerations for soils: permeability, bedrock, slope, coarse-textured layer2
3. Organic Material
Low % organic material3
Brent: Low organic material percentage=more clay. Organic material provides substrate for microbial activity. Plants rely on this for fixation of nutrients so they can draw them up from the soils. Because the pond is so new, there isn’t much organic material or sediment. It will take some time for the natural level of sediment to increase.

4. Sediment Oxygen Consumption At Room Temperature
2012
Average Oxygen Consumption Per day= 0.53 mg/L
2017
Average Oxygen Consumption Per day= .01 mg/L

5. Sediment Oxygen Consumption at 4°C
2012
Average Oxygen Consumption Per day= 0.2 mg/L
2017
Average Oxygen Consumption Per Day= 0.00 mg/L

6. Macrophytes and Their Phosphorus Content
Brent: White markers are sample sites
Green - polygon of where we thought the macrophytes were
Calculated total number of macrophytes

7. Macrophytes and their Phosphorus Content
~ 182 pounds of potential algae
due to phosphorus release
Brent: Ways to reduce phosphorus: reduce runoff (fertilizers, seed in the dirt piles of old sediment), monitor other runoff sources from surrounding farmers/neighbors, continue to ward off the geese to prevent further fecal matter entering from wild sources.

8. Things To Consider... How much fishing pressure will the pond receive?
Will the fish caught be harvested?
How much effort will be put into pond management?

9. Primary Fish to Stock Bluegill Feed on invertebrates.
Provide food for predator fish.
Smallmouth Bass
Control bluegill populations.
Channel Catfish
Feed on plants and fish.
Resistant to low O2 levels.

10. Other Possible Fish to Stock
Control Aquatic Weeds
Algae is good for producing O2.
Too much algae can create anoxic conditions.
Stocking triploid grass carp can help with weed control.

11. Let’s Talk Numbers Species Stocking Rate Per Acre Unit
Stocking Rate for Your Pond

Channel Catfish
Grass Carp 4 3

12. Avoid Overstocking Having extra space is not a problem.
Not having enough space is a problem.

13. Lower Density Leads To Increased Growth
Both growth performance and survival rate tend to be higher in lower stocking densities.

14. Final Recommendations
Habitat Modification
Creating artificial habitat can help your pond thrive.
Examples include: gravel beds, fallen logs, tires, etc.
Plant in the soil pile
