Paklicko Wielkie is a flow-through lake located in the Lubusz Voivodeship, situated in the Łagów Lakeland within the Świebodzin municipality. It covers an area of 196.9 hectares, with an average depth of 8.1 meters and a maximum depth of 22.5 meters. The lake is part of the post-glacial Jordanów-Niesulice trough and lies within the protected landscape area known as the "Paklica and Ołobok Trough." Its shoreline is varied, featuring a northeastern peninsula and high, dry banks along the southern and western coasts. The Paklica River, a left tributary of the Obra River, flows through the lake, significantly influencing its ecosystem. The lake's vegetation is dominated by common reed and shining pondweed, while its rich plankton supports a diverse range of fauna, including waterbirds such as mallards and great crested grebes. Water quality assessments have indicated varying levels of cleanliness, highlighting issues with pollution that affect its overall condition. Historically, the area around the lake has been a site of rich settlement dating back to the Mesolithic era, with numerous archaeological sites, including traces of a Slavic settlement from the turn of the 8th and 9th centuries. In the 1930s, the lake's surroundings were part of the Międzyrzecz Fortified Region, which held military significance during World War II. Today, the lake is an important recreational destination, featuring bathing areas and kayaking routes, and attracts tourists to a resort located on its peninsula.
