The springs have an average flow rate of 5,000 liters per second, making them among the most significant in Central Italy.
The water temperature remains steady at 10-11 degrees Celsius throughout the year, even during peak summer months.
The site was historically exploited for a flour mill and an oil mill that utilized the consistent hydraulic power of the springs.
The basin is known for the high oxygenation and purity of its water, which supports local salmonid populations.
Sorgenti Santa Susanna is a natural spring system located in the province of Rieti, characterized by its remarkably clear, constant-temperature water that forms a significant aquatic basin. The site features an artificial lake created by the damming of these springs, which historically powered local milling and industrial activities. The water maintains a constant temperature of approximately 10 degrees Celsius year-round due to its deep groundwater origin. The springs are a critical water source for the surrounding landscape and support a rich riparian ecosystem. The site is situated near the remnants of ancient industrial structures that utilized the hydraulic energy of the springs. The area serves as a habitat for diverse freshwater flora and fauna, including trout, which are visible through the transparent, spring-fed water.

Bring polarized sunglasses to better see through the water's surface reflection to the bottom of the basin.
Wear sturdy walking shoes to navigate the gravel and natural paths surrounding the spring perimeter.
Avoid entering the water directly, as the constant 10-degree temperature can cause immediate thermal shock.
Respect the protected natural environment; do not feed the fish or disturb the water vegetation.
