Conservation encouraged as drought persists on Cape Cod

Cape Cod remains in a Level 2 (Significant) drought, according to the most recent designation from the state’s drought management task force. The declaration, issued in April based on March data, reflects ongoing conditions across the region and much of Massachusetts.

It’s easy to think of drought as simply “dry weather,” but it’s better understood as a deficit in the water budget: less water available than what is typical for a given place and time. Not all dry conditions are drought. A desert is naturally dry, but not always in drought. On Cape Cod, as elsewhere, precipitation doesn’t fall evenly across the landscape or seasons. What matters is whether rainfall falls short of what is normally expected.

Drought also has a time dimension. A single rainy month may not be enough to erase a deficit built up over six or ten months of below-average precipitation. Water systems take time to recover. Aquifers need to recharge, rivers and streams must rise again, and soils must regain their moisture. Even after it rains, it can take much longer for the supply to return to balance.

Cape Cod Commission Water Resources Manager Tim Pasakarnis shared an overview of current conditions and response strategies during a presentation to the Barnstable County Board of Regional Commissioners at its March 25 meeting in Eastham.

Pasakarnis noted that while the drought designation applies to the entire Cape Cod region, the issue is not unique to the Cape. “This is not a Cape Cod-specific topic of interest,” he said. “This is happening throughout the state.”

The Level 2 classification is based on multiple indicators, including precipitation, streamflow, groundwater levels, and conditions in lakes and ponds. While precipitation trends alone may suggest less severe conditions, other measures, particularly groundwater and surface water levels, indicate greater stress on the region’s water resources.

Recent snowfall and late-winter precipitation have only been reflected in the most recent data used for the current declaration. Because the ground remained frozen, much of that water may still be recharging the aquifer, and while conditions improved from February to March, they are still indicative of a Level 2 Drought. Updated conditions are expected to be evaluated at upcoming task force meetings.

Looking ahead, seasonal forecasts show equal chances of above- or below-average precipitation and temperatures, offering little clarity on how conditions may change in the coming months. As a result, planning and conservation remain key priorities, particularly as the region approaches the summer season.

Pasakarnis noted that building a culture of conservation is critical. “We want to make that just a daily sort of thing,” he said, “knowing that conservation before peak demand season can provide more flexibility in the event that these conditions continue.” Warmer temperatures, increased outdoor water use, and a growing seasonal population all contribute to higher demand during the summer months.

Water suppliers across the region are encouraged to take both short- and long-term actions, including evaluating water use policies, exploring infrastructure improvements, and developing interconnections with neighboring systems to improve reliability.

At the same time, public awareness plays an important role. Helping residents and visitors understand how everyday water use affects the Cape’s sole-source aquifer can support more consistent conservation efforts.

While Cape Cod’s aquifer receives significant recharge in a typical year, and current withdrawals represent a relatively small portion of that total, Pasakarnis noted that water supply challenges are not simply a question of overall volume.

“The overall volume of water is generally not the issue,” he said. “But accessing that water in the way that we want, at the time that we want, is.”

Water systems are subject to physical and regulatory limits, which can become more pronounced during peak demand periods. On the Outer Cape in particular, the structure of the freshwater aquifer and limited system redundancy can make supplies more vulnerable to stress.

These constraints highlight the importance of managing existing resources carefully while planning for the future. Developing new water supplies can take years and is limited by available land, making conservation and efficient use of current systems the most immediate and effective strategies.

As drought conditions persist, regional coordination, continued public education, and proactive planning will be essential. While future conditions remain uncertain, reducing demand, strengthening system resilience, and preparing for seasonal pressures will be key to ensuring a reliable water supply for Cape Cod.

Residents and businesses in areas experiencing Level 2 drought are encouraged to minimize overall water use, follow local water use restrictions, and fix indoor leaks (such as from toilets, faucets, and showers). For any upcoming outdoor water use, limit watering to hand-held hoses or watering cans, to be used only after 5 p.m. or before 9 a.m. Larger buildings and businesses are encouraged to conduct water audits to identify areas of leaks and potential water conservation opportunites.
