Redberry Lake (Saskatchewan)
open-in-new
<p>Redberry Lake is a <a href="/facts/Kettle_(landform)/RsryhrNA">kettle</a> <a href="/facts/Salt_lake/gEtjt4Rl">salt lake</a> near <a href="/facts/Hafford/05zt6g1H">Hafford</a> in the <a href="/facts/Provinces_and_territories_of_Canada/k3o89TLx">Canadian province</a> of <a href="/facts/Saskatchewan/ehkUec57">Saskatchewan</a>. Named after the <a href="/facts/Shepherdia/2v29gYjM">buffaloberry</a>, it is a medium-sized <a href="/facts/Salt_lake/gEtjt4Rl">saline lake</a> within an area characterized by mostly <a href="/facts/Fresh_water/xMP2TxwI">fresh water</a> aquatic environments. The lake makes up the core protected area of the <a href="/facts/Redberry_Lake_Biosphere_Reserve/u6cFvp5n">Redberry Lake (UNESCO) Biosphere Reserve</a> and is a federal <a href="/facts/List_of_Migratory_Bird_Sanctuaries_of_Canada/MtL2RHtN">bird sanctuary</a> of the same name. It is also an <a href="/facts/Important_Bird_Area/lNzQytd9">Important Bird Area</a> (IBA) of Canada and its northern most island is the location of the provincial Redberry <a href="/facts/List_of_protected_areas_of_Saskatchewan/WCzMmY8J">Wildlife Refuge</a> (<a href="https://geohack.toolforge.org/geohack.php?pagename=Redberry_Lake_(Saskatchewan)¶ms=52.7001_N_107.2006_W_">52°42′00″N 107°12′02″W / 52.7001°N 107.2006°W / 52.7001; -107.2006</a>). A small <a href="/facts/List_of_protected_areas_of_Saskatchewan/WCzMmY8J">regional park</a> is situated at the north-west corner of the lake. The countryside surrounding Redberry Lake is typical of the <a href="/facts/Aspen_parkland/vHwwo7by">aspen parkland</a> biome of which it is a part. </p><p>Over the past several decades, Redberry Lake water levels have been declining and the salt concentrations increasing. With the declining levels, the shoreline length has been decreasing and the size of the islands in the lake have been increasing. In 1957, a new island — New Tern Island — appeared. In the 1940s, the salt content was low enough that there was a thriving commercial <a href="/facts/Lake_whitefish/A3YwNXGn">whitefish</a> industry at the lake. </p>
