Hundreds of Finnish wells at risk of drying up this summer

Finnish summer cottage owners face widespread well shortages as groundwater levels across the country remain exceptionally low, according to the Finnish Environment Institute (Syke).

Hydrologist Sami Soosalu reports that measurements at most Syke monitoring stations show levels 20–70 cm below average, with some areas in Kainuu recording deficits of 115 cm. A low-snow winter and early spring reduced the usual recharge from melting snow, leaving aquifers depleted before the summer drawdown.

If warm, dry weather persists, hundreds of wells—particularly shallow dug wells—could run dry in the coming weeks. Rain may provide temporary relief, but prolonged drought would accelerate declines, especially in smaller aquifers.

Soosalu advises well owners to monitor both water levels and quality, as deterioration often precedes complete depletion. Conservation measures, sediment removal, or deepening may be necessary for frequently affected wells.

In Pieksämäki, cottage owner Olavi Nenonen finds only a few centimetres of water remaining in his six-ring well. He has adjusted habits, avoiding large laundry loads and preparing to haul water by tanker if needed. Nearby lake levels are also at historic lows, with some basins breaking century-old records.
