New York buoy tracks drinking water reservoir conditions as water costs loom for households

A five-foot buoy weighing 700 pounds floats in Otisco Lake, New York, and while it may seem unusual to passing boaters, its purpose has nothing to do with leisure on the water.

Powered by the sun, the device is intended to help safeguard a key drinking water reservoir and, ideally, prevent worsening lake conditions from driving up costs for New York households.

According to NNY360 , the Upstate Freshwater Institute placed the faded yellow buoy in Otisco Lake in June to measure conditions throughout the water column and send that information to Syracuse twice each day.

The effort centers on heavy nutrient loading that researchers say may be causing the reservoir to age faster than other Finger Lakes. When the quality of a drinking water source declines, utilities can end up paying more for treatment, oversight, and major repairs, with those added expenses eventually reaching customers.

Otisco Lake supplied 44% of the water moving through the Onondaga County Water Authority's system. Lake Ontario provided more than half of the region's water, while Skaneateles Lake contributed 3%.

Because Otisco Lake serves so many people in Central New York, residents and conservation advocates see the buoy as a needed step that should have happened sooner.

If nutrient pollution continues to worsen, utilities may need to devote more resources to keeping water safe and reliable. That can put pressure on both public budgets and monthly household expenses, as well as overall household values.

"People have put a lot of money and a lot of effort into their homes out here and the property values will be very heavily influenced by what happens with the quality of the lake," said Russ Holihan, a resident of Otisco Lake for more than six decades and a member of OLPA's advisory board.

Excess nutrients can accelerate a lake's aging process, contributing to murkier water and more difficult-to-manage conditions. In reservoirs used as drinking water sources, prevention and early detection are typically far less expensive than responding after problems become more severe.

Instead of relying only on periodic sampling, the system can collect ongoing measurements and provide a clearer picture of what is happening beneath the surface, NNY360 noted.

By collecting data twice a day, the buoy gives scientists a better chance of identifying trends tied to nutrient loading and shifting water conditions before they grow into larger problems.

County support for the monitoring program totals $64,000 over two seasons, funding that Onondaga County 6th District legislator Gregg Eriksen helped secure. That investment is relatively modest compared with the potential cost of treating a more degraded water source or paying for larger infrastructure responses later.

Better data can also help decision-makers identify the most effective ways to protect the lake, whether that means improving runoff management, refining treatment strategies, or prioritizing watershed conservation. The buoy is not a solution on its own, but it can help guide more affordable decisions.

Keeping source water cleaner can help utilities avoid some of the highest treatment costs, protecting both public health and consumer budgets.

The buoy's daily readings may help shape how the region keeps that water safe — and how much families ultimately pay for it.

Eriksen is confident data collected by the buoy will put OLPA in a better position to qualify for more funding down the road.

"That's what the real eventual hope is," he said, according to NNY360. "That this buoy can collect the data that's going to lead to more good things for this lake."
