Drainage area for the Windy Run monitoring site.
Location
Windy Run is located in north Arlington.
Drainage Area
Windy Run drains directly into the Potomac River. The drainage area is one-half of a square mile, and 21 percent of the watershed is impervious.
Rapid Stream Assessment Technique Scale: Fair
In 2011, we assessed all the streams in the County as part of the Stormwater Master Plan Update. The assessment used the Channel Evolution Model to evaluate which sections of the streams are actively eroding to prioritize them for stream restoration. During that assessment, Windy Run was found to be a priority stream for restoration given that almost 75 percent of the stream length was in an actively eroding state, with only 6 percent artificially stabilized.
Macroinvertebrate Monitoring Data
The monitoring site is located downstream at the end of North Kenmore Street along the nature trail.
Macroinvertebrates commonly found are:
- Black flies
- Fingernet caddisflies
- Midges
- Net-spinning caddisflies
- Small minnow mayflies
- Snails
In fall 2011 and spring 2012, we contracted a professional monitoring group to collect family/genus-level macroinvertebrate and fish data at each of our volunteer monitoring sites.

Bacteria Monitoring Data
There is one bacteria monitoring site on Windy Run located downstream from the end of North Kenmore Street. Learn more about bacteria monitoring data.
- Blue line: Measured bacteria levels.
- Orange line: Primary contact recreation water quality standard, 235 E. coli CFU/100 mL. Primary contact recreation activities have a high probability for total body immersion or ingestion of water, like swimming, canoeing and kayaking.
- Gray line: Secondary contact recreation water quality standard, 1,173 E. coli CFU/100 mL. Secondary contact recreation activities don’t have a high probability of total body immersion or water ingestion, like skipping rocks or fishing.
