Nesslin Lake is near the western boundary of Prince Albert National Park[3] and is entirely within the Nesslin Lake Provincial Recreation Site. It is about 21 kilometres (13 mi) north-east of Big River and access is from Nesslin Lake Road, which branched off Highway 922. The community of Nesslin Lake, at the southern end of the lake, is the only community at the lake.[4][5]
In 2019, the lake water level rose significantly causing some flooding of amenities along the lake's shore. This was the result of a beaver dam being removed during the construction of a logging road north of the lake.
"The removal of a beaver dam resulted in a rapid release of water and sediment into a creek that flowed south into Nesslin Lake," Saskatchewan's Ministry of Environment said in a statement. "This altered the creek channel and caused the lake's water level to rise significantly in a short time, causing flooding and reduced water quality."[6]
