Water Temperature
Water temperature plays a key role in shaping life in the Hudson River. It determines which fish and other aquatic species can survive and how they migrate. Temperature also affects the river’s dissolved oxygen levels—warmer water holds less oxygen than cool water, which affects what kinds of organisms can survive.How much has the Hudson warmed since 1947?
1.7 °FDissolved Oxygen
When oxygen is in water, it is referred to as dissolved oxygen. Because it is used by fish to breathe, the amount of dissolved oxygen in the water can tell you how healthy the water is for fish and other aquatic organisms.How much oxygen do fish need?

Turbidity
Turbidity is a measure of water clarity. Suspended material in water- such as clay, silt, microorganisms, and plant matter- all cause higher turbidity. Water with high turbidity may appear cloudy or murky due to particles preventing light from passing through, which affects the growth of underwater plants. Sediment carried by stormwater can increase turbidity.Intense rainfall events can cause high turbidity by washing particles from the land into streams.
Specific Conductance
All natural waters contain salts and minerals. The more dissolved salts and minerals dissolved in water, the more electricity it conducts. We measure electrical conductivity in siemens. Knowing that tells us how fresh or salty the water is and whether it’s habitable for different species of fish. The Hudson is home to many species of fish that thrive in fresh, brackish, or seawater—or even a combination of all three.How salty do they like it?
