The name of the lake derives from Siberian Tatar ubu, meaning swamp or marsh.[1] During spring melt Lake Ubinskoye covers a maximum area of {{convert|440|km2}} and is {{convert|2.0–2.8|m}} deep; during periods of low water it is only {{convert|0.6–1.0|m}} deep, and in October 2013 it was estimated from aerial imagery to cover {{convert|350|km2}}. The lake drains an area of {{convert|2990|km2}}. Lake Ubinskoye is mainly fed by melting snow and usually has no outlet, but in the spring of some years it overflows into the Ubinke River, a tributary of the Om River.[1] Lake Ubinskoye is an oval-shaped lake with gently sloping banks. The lake bottom consists of clayey sand covered by a thick layer of gray fine-grained silt.[2] There are several islands in the lake, the largest of which is called Medyakovsky. The western part of the Ubinskoye basin also contains a number of other small lakes.[1] Lake Ubinskoye freezes over from November to late May. The ice on the lake is {{convert|0.7–1.0|m}} thick. In summer the water warms up to {{convert|20–24|°C}}. The temperature is uniform throughout the water column due to good mixing. The water pH is between 7.6 and 9.0. Ubinskoye is a mesotrophic lake whose plankton is dominated by green and blue-green algae.[1] The shores of the lake are overgrown with reeds and sedges. In the mid-20th century Lake Ubinskoye was well known for its abundance of fish: bream (introduced in 1929[3]), roach, pike, ide, carp, and peled were exploited commercially. Fish stocks crashed in the 1990s, likely due to the lowering of the water level; currently only small crucian carp remain. Attempts to restock the lake have failed, but a recent increase in water levels gives hope for future efforts. The lake and its surrounding wetlands continue to host a great variety of bird life.[1] Lake Ubinskoye is surrounded by several villages, the largest of which is Chernyy Mys on the north shore.[1] According to legend, Kuchum, the last Khan of Sibir, flooded his treasure in the lake while fleeing from the Russians.[3] References1. ^1 2 3 4 5 6 {{cite web |last=Izmaylova |first=A.
