Lakes in upper reaches of Issyk River in Almaty Nature Reserve.

"Lake Boz-Kul is empty. Its gray sandy bottom is cut by several channels of a stream flowing here from the Kassin Glacier. The waters of this stream seep into the sandy bottom and continue along the underground runoff. At the foot of the Boz-Kul Dam, they and other streams that have joined them emerge. But when the Kassin Glacier melts especially intensely, the stream covers the bottom of Lake Boz-Kul with a thin layer of water for several hours (from evening until morning)."

A trip to Lake Boz-Kul in upper reaches of Issyk Gorge.

Lake Boz-Kol, a moraine, freshwater lake, is located at an altitude of 2,643 m. a. s. l. in upper reaches of Kokbulak River, a left tributary of Issyk River. It is 5.2 kilometers southeast of Lake Muzkol, 3.2 kilometers southwest of Lake Akkol, and 6.6 kilometers north of middle branch of Grigoriev Glacier. It is located within Almaty Nature Reserve in Enbekshikazakh district of Almaty region.

Upstream of the Issyk River, in the uppermost reaches of the spruce forest, lies Lake Boz-Kol. The lake is backed by a high embankment of ancient glacial deposits consisting of rock and gravel. The entire embankment and adjacent mountain slopes are covered with Schrenk spruce and shrubs.
From the left side gorge, the moraine rampart of the Tesken-Su Glacier approaches it, completely encased in a mantle of rock debris. Lake Boz-Kol, its gray sandy bottom cut by several channels of the inflowing stream from the Kassin Glacier.
The waters of this stream seep into the sandy bottom and continue along underground sources. At the foot of the Lake Boz-Kol dam, other streams also flow into the main channel and emerge. When the Kassin Glacier melts particularly intensely, the stream covers the bottom of Lake Boz-Kol with a thin layer of water for several hours (from evening until morning).
Beyond Lake Boz-Kol, the forest soon ends. Subsequently, the river valley is once again blocked by a stone dam, formed by an ancient glacier and rock falls. At the rock-covered end of the Grigoriev Glacier, a small moraine lake, the fifth in the Issyk River valley, glistens green.
It lies below the mountain sections where glacial streams are born. The majestic panorama of the river's upper reaches is capped by the snow-covered, flat ridges of the main range. On a clear, sunny day, they sparkle like well-cleaned enamel; during windy and cloudy weather, the whitish dust of a snowstorm hovers above them.
