Isoletta

Isoletta is a village in Italy, in the Valle Latina within the Arce municipality. Isoletta is located in the province of Frosinone, of the southern Lazio region in Italy. Geography Isoletta is located in the Frosinone province, approximately 7.36 kilometers north of Arce. It is bordered by San Giovanni Incarico to the southeast, Falvaterra to the southwest, and Ceprano to the northwest. The Liri River and Lake Isoletta, also known as Lake San Giovanni Incarico, are located in this region. The lake was created in 1925 by the Pontefiume Dam to provide water for hydroelectric power generation. Its reservoir has an abundance of aquatic vegetation due to its inflow of phosphorus- and nitrogen-rich organic material from agricultural and residential runoff. A reserve was established in 1997 in order to protect the area's natural and historical landmarks, including Fregellae, Fabrateria Nova, and the lake of San Giovanni Incarico.
