Stormwater solution highlights power of collaboration for China Lake

A serious runoff problem that was dumping phosphorus-laden water into China Lake has been resolved, thanks to teamwork that saw private landowners, nonprofits, and government agencies joining forces with the goal of protecting the lake’s water quality.

The issue originated with a culvert that drained runoff under Lakeview Drive from 40 acres of woodland east of the road. In 2015, new owners of what would become The Cottages at China Lake installed an additional culvert to direct runoff from the roadside into a plunge pool near the shoreline. Over time, the pool filled with sediment and vegetation. “The water would rush straight into the lake, untreated and uncontrolled,” said John Perron, a Cottages owner and member of the property’s buildings and grounds committee.

Recognizing the problem, Perron and Cottages’ association president Mike Stillman contacted Scott Pierz – then head of the China Region Lakes Alliance (CRLA), and former president of China Lake Association – who they knew had previously been involved in shoreline protection at the property. “It was really time to take up the task,” Pierz said.

He brought in CLA, which then reached out to the state Department of Environmental Protection and Kennebec County Soil and Water Conservation District for additional help.

“This was a highly collaborative effort,” said CLA President Stephen Greene. “Everyone had the lake’s best interest in mind.”

Eventually, Boyd Snowden, of Snowden Consulting Engineers, was brought into the fold to design a site plan, which was developed over a year’s worth of visits, planning and permit approvals. The final design included a plunge pool, catch basin and vegetated buffer to trap sediment and slow runoff before it reached the lake.

“We didn’t just stop at the basics,” said Snowden, who has been designing storm-water containment systems for more than 30 years. “We added a meadow buffer to provide the best treatment possible.”

Funding came from multiple sources. Maine DEP authorized KCSWCD to allocate $14,000 through a federal grant* aimed at reducing phosphorus in China Lake. CLA contributed $9,321, matched by the Cottages’ 20 owners, while CRLA provided $5,000.

Construction began in October 2024 after permits were secured. Over the course of a week, W.D. Chadwick Construction installed the multi-tiered system, which now filters the runoff, trapping sediment from running into the lake – and fueling algae growth and harming water quality. Fieldstone Gardens, of Vassalboro, supplied plants for the buffer area.

Pierz expressed confidence that the Cottages’ association will maintain the system and continue improving shoreline protections. Greene praised the project as a model for collaboration between private owners, nonprofit organizations, government agencies and contractors.

“This project shows how teamwork and a shared goal can solve complex problems,” Greene said. “The China Lake Association is proud to have been a part of a solution that will benefit the lake for decades to come.”
