A U.S. Geological Survey is closely monitoring the Brandywine Creek, collecting real-time data on the health of the local treasure, writes Pete Bannan for the Daily Times.

The monitors are in a narrow, concrete-block building behind the Brandywine River Museum. They are checked once a month by USGS employees, one of whom is hydrologic technician Mason Manis.

“Overall, the water quality is pretty good; I swim and canoe in it myself,” said Manis.

The tests he performs include checking levels, water quality, cloudiness or haziness, and temperature.

The USGS also monitors the Brandywine from its stations in Honey Brook, Coatesville, Modena, and Broad Run in Downingtown. Residents have the option of checking the data from each location on the USGS website.

According to USGS biologist Drew Reif, the Brandywine is doing well.

“I haven’t seen it better in the 30 years I’ve been here,” he said.
