Turin, Italy – April 6, 2024: Piedmont, a region in northern Italy, experienced record-breaking rainfall in March, significantly replenishing its water reserves. The month saw 280 mm of accumulated precipitation in the Po basin, marking the highest levels in the last 70 years and quadrupling the normal precipitation for March in the region.
According to data from ARPA Piedmont, the rainfall was concentrated in two events, one in the first decade of the month and another in the last week. This abundance of rainfall, coupled with the significant precipitation in February, has left the region in a healthy state in terms of water availability.
The surplus of precipitation has had a positive impact on water reserves across Piedmont. Currently, stored surface water is estimated to be about double the normal amount for this time of year, with Lake Maggiore showing a surplus of 54%. Additionally, the snow water equivalent (SWE) is more than double the norm, with values at a record high for this period.
The March rains have not only compensated for flow deficits in some watercourses from February but have also led to flow surpluses across all basins of the region. Northern and eastern sectors, particularly affected by the precipitation, have seen flow surpluses exceeding 150%.
Moreover, groundwater levels, which had been low due to two consecutive years of drought, are slowly recovering thanks to the recent rains. While some areas still have groundwater levels above the 75th percentile, indicating a significant recovery, others remain below the 25th percentile or the average value of the historical series.
Overall, the record rainfall in March has significantly improved the water situation in Piedmont, ensuring a healthier environment and water supply for the region.
Conclusion: The abundant rainfall in March has not only replenished Piedmont’s water reserves but has also contributed to improving the region’s overall water situation. With groundwater levels slowly recovering and surface water reserves at healthy levels, Piedmont is better equipped to face future water challenges.
