HARRISON — Officials say they’re encouraged by early results from an experimental program to use aquatic barriers to keep phosphorus out of Crystal and Long lakes in the town of Harrison, Maine
The partnership between the University of Southern Maine, the Lakes Environmental Association in Bridgton and Scarborough-based Mackworth-Enviro installed curtain-like barriers around culvert drainage inlets.
The 600-foot-long aquatic filter barriers catch runoff water and prevent phosphorus from fertilizers from entering the lakes.
Colin Holme of the Lakes Environmental Association said that storm runoff with nutrient phosphorus can wreak havoc on lake ecosystems and promote algae growth.
Holme says the barriers will remain in the lakes until the end of this month or early September. Then data will be tabulated to confirm that the system is working as intended.
