Stormwater Management Ponds are man-made ponds designed to prevent flooding and act as a reservoir for the rainwater as well as the surface runoff that fills them from the higher elevations surrounding. These ponds generally have a weak current, if any at all and absorb sunlight all day which allows perfect conditions for algae growth and eutrophication of the water body. Nutrients and other debris associated with surface runoff and atmospheric deposition become introduced into the pond and feed these algae. I became curious about these sources so I came up with the official scientific questions of:
1. Does the setting surrounding an SMP influence the input of nutrients by surface runoff?
2. Does atmospheric deposition play a role in nutrient input?
Below, TPSMP, is the Tuscawilla Park Stormwater Management Pond located in Tuscawilla Park in Daytona Beach.

Materials I worked with include:
- Field Journal
- 4 2-Gallon Pail w/Handle
- Hach 2100N Turbidimeter
- Hack DR/890 Colorimeter
- VWR Clinical 20 Centrifuge
- NOAA Surface Weather Maps
- 500mL Bottles for Water Samples
- AquaFluor Handheld Fluorometer
- Wide Mouth Quart-Size Mason Jars
- NOAA Hi-Def Radar App for iPhone
- Fisher Scientific MaximaDry Filter Pump
3. Once the storm had passed, three new samples were collected from the same sites and stored in a cool, dark place for later analysis using the same methods listed earlier.
