|Bottom Dissolved Oxygen (mg/l)|
|0.0 - 0.2 (anoxia - kills most life)|
|0.2 - 2.0 (hypoxia - harms bottom organisms)|
|2.0 - 3.0 (stresses smaller fish and crabs)|
|3.0 - 5.0 (stresses larger fish)|
|5.0 - 10.0 (healthy)|
|10.0 + (could indicate an algal bloom in summer)|
|Dissolved oxygen (DO) in the water sustains life for Bay organisms. Nutrients, such as nitrogen and phosphorus, from agricultural, sewer/septic and urban sources can fuel algal blooms that can starve the water of DO. DO levels above 5 mg/l are normally sufficient to support most life.
