The Virginia Department of Health (VDH) has expanded their Harmful Algae Bloom Advisory for recreational activity in the North Fork to include a 52.5 mile stretch of the North Fork of the Shenandoah from Chapman’s Landing, near Willow Grove, to Riverton, near Front Royal.

If you see an algal mat, do not enter the river and keep your pets away.  Not all mats are toxic, but when in doubt, stay out!

You can help Friends get a clearer picture of the scope of this problem by emailing us a photo of the river around where you live or like to recreate to [email protected].  We are also looking for a few people to document local sites weekly to track the progression of blooms.   Please include the location of your photo and any other observations you have, i.e. wildlife, fish, odor, litter, river flow, etc.  If you are able to send a weekly photograph to monitor your spot until the fall, please let us know in your email. 

Check out the map below for photos already collected from around the North Fork.  

We will share a digest of these collected reports with VDH, DEQ, and the Shenandoah Riverkeeper to aid in their efforts to test for harmful algae, keep the public informed, and combat the source of algal blooms. Friends will not share your name or any personal information in connection with any photos you submit, unless you note that you would like to be credited.
