Evaluation of the lakes and impoundments drought index for the Massachusetts Drought Management Plan

The condition of surface water storage in lakes and impoundments is used as an index of drought in the Massachusetts drought management plan. The U.S. Geological Survey visited 28 of these lakes and impoundments at 14 single and multiple waterbody systems to evaluate their appropriateness for characterizing drought. The data collection and computation methods at each system were then reviewed and

Estimating groundwater level records using MOVE.1 and computing monthly percentiles from estimated groundwater records in Massachusetts

The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, performed record extensions on groundwater levels at select wells using the Maintenance of Variance Extension type 1 (MOVE.1) method. The groundwater levels estimated from these record extensions were used to compute monthly percentiles to improve future determinations of a groundwater index.

Simulated mean monthly groundwater-transported nitrogen loads in watersheds on the north shore of Long Island Sound, 1993–2022

Elevated nitrogen loads are pervasive in the Long Island Sound, an estuary that receives freshwater and nutrients from both surface-water and groundwater discharge. Surface-water nitrogen loads to the Long Island Sound are relatively well characterized, but less is known about groundwater-transported nitrogen loads. Prior work on the northern shore of Long Island Sound (Connecticut and areas of Ne

July 2023 Flood in Vermont

From July 9 through July 12, 2023, 3 to 9 inches of rain fell within 48 hours across the state of Vermont, causing catastrophic flooding and millions of dollars in damage. The high amount of rain caused several rivers to peak at record levels, in some cases exceeding records set during Tropical Storm Irene in 2011.

Continuous Water Quality Monitoring in the Norwalk River Estuary

The U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency Long Island Sound Study (LISS), is investigating how excess nutrients and low dissolved oxygen affect the water-quality of the lower portion of the Norwalk River Harbor.
