Algal and Aquatic Plant Assessments
The Algal and Aquatic Plant Assessment Program provides support for the Ambient Monitoring System, Ambient Lakes Monitoring System, Planning Section, and Regional Office staff in the analysis of algal and aquatic plant assemblages. The major focus is on phytoplankton, which are suspended microscopic plants found in the water column capable of photosynthesis. However, other types of algae, such as filamentous and periphyton, are also analyzed.
Analyses are performed to:
• Identify algae and aquatic plants
Two types of evaluations are performed by the program: episodic and routine. Samples for episodic evaluations are collected in response to specific events such as fish kills, algal blooms, and nuisance aquatic plant and algal growth. Routine evaluations are targeted studies of specific waterbodies of interest and are generally performed in cooperation with other DWQ programs. Routine evaluations are conducted to assess changes in algal assemblages over time and are often focused on estuarine systems where there are known issues of nutrient enrichment and have had frequent algal blooms or fish kills.
If you wish to report a fish kill, algal bloom or potentially problematic growth, contact your local regional office or the rapid response team in your area.
