Water Site #1

Temperature is a measure of the degree of hotness or coldness of a body or environment.
Air Temperature: 102◦ F
Water Temperature: 90 ◦ F
The cooler the water is the more oxygen is available for the organisms.

Turbidity is muddy or opaque, as a liquid clouded with a suspension of particles.
Turbidity was 60 cm, which is very good.
Turbidity of water site #2 was 27 cm.
Turbidity

DO is the amount of oxygen present in the water.
DO was 13 mg/l oxygen (highest of the 3 sites)
Dissolved Oxygen (DO)

pH is a measure of the acidity or alkalinity of a solution, The pH scale uses ranges from 0 to 14 with 7 considered neutral. Less than 7 is more acidic and greater than 7 becomes more basic.
pH for our water site was a 9

Nitrates are a salt or ester of nitric acid, containing the group NO₃. They dissolve extremely easily in water and are an important component of the nitrogen cycle.
Nitrates: 3.6 mg/l ammonium nitrogenNitrates: 3.9 mg/l nitrogen
This stems from the history of horse stables being up hill from the water site.

Biodiversity is the existence of a wide variety of plant and animal species in their natural environments.
We found all of the following: skunkweed, mite, mayflies, scud, leech, dragonflies, backswimmers, left handed snail, boatman, damsel flies, aqua worms, tadpoles, pollywogs, frogs, bluegill sunfish, mosquito fish, Dwarf American toad, etc.
This site had fish so all the Macroinvertibrates were much smaller than from site #2.
The more predators the smaller the prey.

Very HealthyWater site 3 was also very healthy but we
believe ours is the healthiest.
Healthy or Not?

High DO
Great Turbidity

This water site is thriving and can support many different types of plants and animal species.
It can also support a wide range of Macroinvertibrates.
This also means the fishing is GOOD!
What does it mean?
