UW researcher warns Middleton ponds are nutrient‑rich, emit methane and need funding to continue monitoring
Summary
Grace Laviart of the University presented three years of local pond monitoring showing most Middleton ponds are nutrient‑enriched (hyper‑eutrophic), experience low dissolved oxygen and emit elevated methane; she said NSF funding cuts threaten continued data collection and volunteer monitoring.
Grace Laviart, a University researcher, told the Middleton Water Resources Commission that long‑term monitoring of urban stormwater ponds shows widespread nutrient enrichment, frequent low dissolved‑oxygen events and substantial methane emissions — and that continued data collection is at risk from anticipated National Science Foundation cuts.
Laviart said volunteers in the community water monitoring network have collected more than 700 samples from 10 Middleton ponds over about two and a half years. "Most of the ponds are excessively enriched with nutrients," she said, and classified nearly every sampled Middleton pond as "hyper‑eutrophic," a trophic state that supports high algal growth and raises…
