During routine nuisance algae visits, DEQ colleagues informed us they observed cyanobacteria mats growing along the river bottom near Strasburg Park. Mats observed are not dense or floating to the surface, just growing.
DEQ is scheduled for a visit back in the area next week for sampling related to the ongoing Shenandoah HAB study. DEQ will re-evaluate the mats at that time.
Whenever participating in any type of outdoor water recreation activities, be aware of harmful algal mats. These can be present in bodies of water either attached to the bottom, detached and floating, or washed up on shore. Keep children and pets away from these areas. Though only currently seen in the river at Strasburg Park, always look at the water and use caution when allowing pets or children to play in the water.AlgalMatAlert_factsheet_090622_withQR_HABPage_
