Lough Ree, known as the "Lake of the Kings," is the fifth-largest lake in Ireland by area, covering approximately 105 square kilometers (41 square miles). It is the second largest of the three major lakes on the River Shannon. The lake is studded with numerous islands and features a varied underwater landscape. While the greater part of the lake is relatively shallow, with depths less than 10 meters, it is characterized by six deep troughs running north to south. The maximum depth reaches about 36 meters just west of Inchmore, with a mean depth of 6.2 meters. The lake's water quality is classified as mesotrophic, but its size creates a range of conditions, leading to local variations in nutrient status and supporting diverse aquatic flora. Lough Ree is a designated Special Area of Conservation, renowned for its rich freshwater ecosystem and exceptional biodiversity, making it a premier destination for anglers seeking pike, trout, and coarse fish.
