Enilchek is a dendrite-type glacier originating around Khan Tengri Peak (6,995 m) with its tongue (43.2 km long and on average 2.2 km wide) descending to 2,800 m ASL.  Northern Enilchek Glacier is 38.2 km long (181.2 sq.km) and Southern Enilchek Glacier is 58.9 km long (567.2 sq.km).

Lake Merzbacher:

• 3,304 m ASL;
• volume – 0.12-0.25 km³;
• deepest point -- 75 m;
• average depth -- 35 m;
• water-surface lake area – 4.5 sq.km.

Lake Merzbacher formed at the end of the Small Ice Age (19^th century).  It has two pools called Upper and Lower Lakes divided by 400 m of elevation and 3-4 km long ice river with the same name.  In its southern part, the lower and larger part of the lake is limited by the glacial “dam”.  Every year (twice a year, in summer and winter periods) the lake’s lower part breaks into the Enilchek River Valley completely losing its water (discharge speed may exceed 1,000 m³/s) and dumping it in the course of 2-7 days via subglacial canals.  At the time of lake outburst, it accumulates 0.06-0.07 km³ of water.  Based on research data, lake bursts occur when water temperature in the lake rises to 10-15° Celsius.

Lake Merzbacher’s outbursts often destroy bridges, roads and other engineering facilities/installations located along the rivers originating in the lake down to the Ak-Suu River on the territory of China.

The Sary-Dzhaz River Basin which includes Enilchek -- the largest glacier in the country – is one of main sources of fresh water and a potential source for hydropower in the region.

The region is of special significance as to investigating the probability of both natural and natural-technogenic disasters.  It also plays an important role in rational water supply in Kyrgyzstan and the adjacent territory of Xinjiang Autonomous Region of China, as well as planning large-scale infrastructure projects (ex.: cascading hydro-power stations).

Based on the observation data of the last decade, climate change is the reason behind the regressing Tien Shan glaciation.  It leads to reduction of shared water resources, activation of mud flows, floods and glacial lake outbursts.  The largest known glacier-dammed Lake Merzbacher is characterized by one of the most severe and regular annual disruptive glacial floods.  It was necessary to examine hydrological, climatic and glacial changes associated with altering region- and global-scale atmospheric circulations, i.e. their effect on the central section of Enilchek Glacier (confluence point of its two branches -- Northern and Southern Enilchek).

Actions:

Enilchek Glacier research was carried out on the premises of Merzbacher Station established jointly by CAIAG and GFZ in August 2009.  Subsequently, it is planned to expand the set of measuring tools used for studying Enilchek Glacier.

Project scope included field research in the Sary-Dzhaz and Enilchek River Basins, collection of measurements from automatic meteo- and seismic stations, hydro-posts on Northern Enilchek Bridge and Southern Enilchek ablation stake.

Automatic meteorological stations provide data on temperature, precipitation, humidity, atmospheric pressure, wind and total solar radiation necessary to reveal the impact of altering climatic parameters on glacier balance, discharge of the Enilchek River and outburst discharge regime of Lake Merzbacher.  Project efforts allowed better identification of summer glacial discharge for separate glaciers (Northern and Southern Enilchek) via automatic hydro-posts.

Water level and ice surface fluctuations in Lake Merz-bacher were subject to monitoring and registration via water pressure sensors developed GFZ, OpenGPS Sensor (laser scanning technology) and visual observations (high-resolution web-cameras).

Results:

The CAIAG monitoring network was established under research grants and third-party project investments.  The installed GPRS-modems allowed to automatically transfer data to CAIAG server on a daily basis.

The network of interlinked stations was created already under the GCO-CA Project, including MRZ1 and MRZ2 stations close to Lake Merzbacher on northern and southern walls of Northern and Southern Enilchek Glaciers.  The third ICED Station – to measure glacier speed and monitor the dam -- was installed on the ice dam.

The project allowed the e-mapping of the Sary-Dzhaz River Basin, making and assessing Enilchek Glacier geophysical and capacity measurements, as well as identifying lineaments, breaks and crossbars near outburst-prone Lake Merzbacher.  Analyses of satellite imagery allowed identifying rock slides in the form of paleoseismic dislocations within the 50 km radius of the merger point of the Sary-Dzhaz River and the Enilchek River (its left-bank tributary).  The deciphered paleoseismic dislocations prove the region’s high seismicity.  In the future, project results can be used for designing and building the Sary-Dzhaz Hydropower Station.

Financial and economic:

The received results manifest an important contribution to planning and implementing secure economic development efforts in the Sary-Dzhaz River Basin, in particular, designing, building and operating hydropower plants in the region.

Environmental:

Project outcomes serve basis for assessing and forecasting climatic and ecological variability of water resources.

Social:

• reduced probability of sudden destruction of engineering facilities;
• increased security for the residents of the Sary-Dzhaz River Basin.

Actions:

Based on the location of RWCCs and with the account of recommendations by akimats (local governance bodies), 8 RWCCs were selected to conduct a survey based on specially prepared questionnaires. Survey results showed that the main issues in target rural areas were water distribution among consumers and drawing up water use plans (WUP) for RWCCs. The proceeding trainings seminars focused on exactly these themes. At the end of the year, the monitoring of the introduction of new water distribution methods was conducted.

Results:

Application of this water distribution practice allowed to sharply reduce the quantity of conflict situations as well as nearly eliminate water losses due to filtration at the canals’ headworks and discharge.

Lessons learnt:

Research and monitoring of Southern and Northern Enil-chek Glaciers and Lake Merzbacher are of paramount importance due to the prospects of developing water, hydropower and mineral resources in the target basin.

Recommendations:

Long-term monitoring of glaciers and lakes is necessary to prevent the devastating outbursts of high-altitude lakes.

Lessons learnt:

Hourly water distribution allows more flexibility in the context of water deficit. After the trainings for water users and WUAs personnel on hourly water distribution, the number of corresponding conflicts decreased.

Recommendations:

Considering the high turnover of RWCC staff, the trainings should be repeated on annual basis. Hourly water distribution schemes should be used in locations/periods of acute water shortage.
