4.14.2026 Municipal Alliance for Adaptive Management

The City of Portsmouth, New Hampshire's Municipal Alliance for Adaptive Management held a meeting on April 15, 2026, focusing primarily on stormwater impact research related to water quality in Great Bay. The meeting featured detailed presentations from University of New Hampshire researchers on storm impacts on river water quality, sediment and particulate matter dynamics, and river flow estimations using USGS gauging data. Discussions highlighted the limited increase in turbidity during storms in rivers compared to much higher turbidity within Great Bay itself, suggesting internal sources of sediment generation in the bay. The group also reviewed methods for estimating river discharge at monitoring sites, including approaches for ungauged tributaries, to improve water quality modeling. While no direct procurement actions such as contract awards or RFPs were discussed, the meeting referenced research funded by the Municipal Alliance for Adaptive Management and emphasized ongoing scientific collaboration and data analysis to inform future environmental management strategies. The meeting concluded with scheduling plans for the next session and no new budget or purchasing decisions were reported.
