<p>metric conversions</p> <p><b>New page</b></p><div>{{unreferenced|date=March 2010}}<br /> The '''Issyk River''' is a river in [[Kazakhstan]] that crosses the [[Issyk Lake]] (not to be confused with the much greater [[Issyk Kul Lake]] in [[Kyrgyzstan]]) and the town of [[Esik]]. <br /> <br /> One of the largest rivers on the northern slope of the [[Trans-Ili Alatau]], its headwaters come from 32 active glaciers that cover an area of {{convert|43|km2|mi2}}. The largest glaciers are the Zharsai with an exposed length of {{convert|3.8|km|mi}} and an area of {{convert|6.37|km2|mi2}}, the Grigoriev with a length of {{convert|3.6|km|mi}} and an area of {{convert|5.86|km2|mi2}}, and the Pal'gov at {{convert|3.8|km|mi}} long with a surface of {{convert|6.95|km2|mi2}}. They descend from the crest of the main divide, which has an average absolute height of more than {{convert|4000|m|ft}}. Within the mountains the river is {{convert|22|km|mi}} long, the gradient of its longitudinal profile is {{convert|102|m|ft}} per kilometer, and the basin area is {{convert|210|km2|mi2}}. <br /> <br /> In its upper reaches the river flows down a very steep slope (10-15°) over the deposits of a moraine overgrown with some vegetation and forms a deep (as much as 70 m) canyon; then, in front of the terminal vegetation-free moraine of the Pal'gov glacier, its longitudinal profile flattens out abruptly_ Here the river forms numerous branches over an outwash plain. Below Lake Akkul' (its absolute elevation is 3,140 m), the longitudinal profile undergoes another sharp drop because a large mountainous obstruction damming the lake and, perhaps, because of moraines buried under the obstruction. <br /> <br /> In 1963, the overspill of [[Issyk Lake]] caused a large [[flood]].<br /> <br /> {{Coord|43.25|N|77.48|E|type:waterbody|display=title}}<br /> [[Category:Rivers of Kazakhstan]]</div>
