DEEP has confirmed the presence of a bloom of didymo on the West Branch of the Farmington River that has created a thick layer on much of the stream bottom in Riverton between the Route 20 bridge, near the former Hitchcock Chair Factory, and the confluence with the Still River (approximately 1 km downstream) and along the eastern bank of the river for approximately 200 meters below the confluence.
The angling community should be mindful that didymo can be transported from one section of the river to another on their clothing and gear. Especially on boots and waders.
What is Didymo?
Didymo is an invasive freshwater algae. During blooms, didymo can form thick mats on the bottoms of rivers and streams.
Why is Didymo bad?
Didymo not only reduces the recreational and aesthetic value of a river, but can also be devastating to it’s ecology. The thick mats produced by this algae cover the rocks and disrupt the life cycle of insects. No bugs = no food for trout.
What can you do?
You can do you part by following a few simple steps:
CHECK – Before leaving a section of stream, remove all obvious clumps of algae and plant material from fishing gear, waders, clothing & footwear, canoes & kayaks, and anything else that has been in the water and look for hidden clumps. Leave them at the site.
CLEAN: Soak/spray & scrub boats and all other “hard” items for at least one minute in either very hot (140°F) water, a 2% bleach solution, or a 5% dishwashing detergent solution. Absorbent materials such as clothes and felt soles on waders should be soaked for at least 40 minutes in very hot water (140°F), or 30 minutes in hot water (115°F) with 5% dishwashing detergent. Freezing thoroughly will also kill didymo.
DON’T WEAR FELT! – Didymo is harder to remove from absorbent items such as felt soles. PLEASE DO NOT WEAR FELT SOLES!
TELL YOUR FRIENDS – The word must be passed along to everyone you know who uses the river. For more information including how you can identify and report didymo blooms, you can download the following documents issued by DEEP:
