The article analyzes the importance of ongoing long-term observations and field research in assessing the state of glacial-moraine lakes. Since the second half of the XX century, 87 mudflows of glacial genesis have been recorded in the northern slope of the Ile Alatau. Mudflows of glacial genesis are considered as catastrophic phenomena, preventing or reducing their damage is possible only taking into account the experience of the past 80-90 years or through comprehensive measures, such as continuous survey, monitoring and evaluation of the areas. Long-term observations and field research of lake surveys of the glacial-moraine complex are essential for Almaty city with a population of 2 million people and economically important facilities located at the foot of the Ile Alatau. During the conducting research the comparative assessment of the scale of mudflow activity and mudflow hazard of different mudflow basins is carried out, the mudflow basins with the highest activity or threatening the facilities of techno-, eco-, and socio-sphere. In order to protect this area from social and economic losses, 3 different methods of preventive measures are carried out to prevent the moraine lakes outburst floods. Therefore, timely and prompt assessment of the state of the lakes, obtained on the basis of research methods, is especially important for prevention and warning of catastrophic mudflows, mudflow hazard forecasting and mudflow risk management.
