North of Almaty, the Kapchagay Reservoir forms a vast expanse of artificial water created by a Soviet hydraulic project on the Ili River. Now both a strategic infrastructure and a summer recreation zone for residents of the region, it combines beaches, water activities, fishing and access to the revitalized city of Qonaev.

Why visit Kapchagay Reservoir

Kapchagay Reservoir is Kazakhstan's largest artificial basin and one of Central Asia's most extensive. It stretches along the Ili River in Almaty Oblast, 60 to 90 km north of the metropolis. With a surface area of approximately 1,847 km², a capacity of 28.1 billion cubic meters and a dam rising over 50 meters high, it is a monumental structure serving hydroelectric power generation, irrigation and inland beach tourism alike.

For travelers, the appeal is twofold: enjoy warm waters and beaches in summer, and observe how human engineering has transformed the steppe landscape, with its ongoing ecological consequences still debated today.

History of the reservoir and dam

A Soviet project from the 1960s-1980s

The Kapchagay Dam was built across the Ili River to generate electricity, regulate flooding and irrigate agricultural lands in southeast Kazakhstan. Its name derives from the ancient narrow gorge "Kapchagaï" submerged by the impoundment. The structure was completed in 1969, with construction work spanning 1965 to 1980. Reservoir filling began in 1970 and continued for nearly two decades, slowed by insufficient water inflow. It was halted in 1982; by 1986, the reservoir was only half full, and by 1991 it still reached just 36% of planned capacity.

From Iliysk to Qonaev

The town of Iliysk, relocated during the reservoir's creation, was renamed Kapchagay in 1970, then Qonaev in 2022 in honor of Dinmoukhamed Konaev. Officially founded in 1970, it stands approximately 80 km north of Almaty on the western shore of the lake. Broad avenues, Soviet apartment blocks, statues of Lenin and Konaev recall its origins. In the 1980s, ambitious industrial projects, including a "Robot" factory, were launched then abandoned following the Soviet collapse.

Consequences for Lake Balkhash

The reservoir's impoundment reduced water flow from the Ili River to Lake Balkhash downstream. Between 1970 and 1985, Balkhash's volume decreased by 39 km³; by 1987, it reached its lowest level, dropping approximately 2.2 meters, accompanied by increased salinity. Kapchagay's aquatic ecosystems also changed: 24 fish species were recorded in 1975, versus 18 by 1980. Nearby villages such as Akozek, Kerbulak and Chengildi were relocated due to rising groundwater tables. Thanks to recent transboundary management agreements on the Ili (whose sources lie in China), water supplies have improved: in 2024-2025, the reservoir reached a level near maximum capacity, contributing to a partial recovery of Lake Balkhash.

What to see and do

Beaches and swimming

The reservoir's shores host public beaches, sometimes basic, alongside private beaches equipped with loungers and parasols. Waters reach 20 to 28°C at the height of summer, making swimming particularly pleasant in July-August. Shallow zones suit families, while stronger swimmers venture deeper to find depths reaching 45-50 meters in certain sections. The lake freezes in winter.

Water activities

The vast expanse and relatively calm waters make the site ideal for numerous aquatic pursuits:

• water skiing, wakeboarding, jet skiing;
• pleasure boating, sailing, paddleboarding, catamarans;
• tube rides and private boat excursions;
• beach volleyball on developed shores.

Fishing

Fishing from shore or by boat in permitted zones remains a signature activity. Species include carp, bream, perch, asp, pike-perch, pike and catfish. Several nearby restaurants serve freshly caught fish.

Qonaev, the "Kaz Vegas"

On the western shore, Qonaev ranks among the region's fastest-growing cities. Since 2006-2007, it has emerged as Kazakhstan's primary gambling zone alongside Borovoye and Shchuchinsk, earning it the nickname "Kaz Vegas." Casinos, nightclubs, hotels and restaurants create an atmosphere starkly different from the more relaxed beach scene.

When to visit

The beach season runs from May to September, with peak crowds in July-August when water temperatures reach 20 to 28°C. Spring and early autumn are quieter and ideal for fishing and walks. In winter, the lake freezes; the site remains accessible but water activities cease.

Practical information

• Location: Almaty Oblast, on the Ili River, 60-90 km north of Almaty.
• Reference city: Qonaev (formerly Kapchagay), on the western shore.
• Duration of visit: one day for beaches, minimum two days if combining water sports, fishing or casino activities.
• Accommodation: rest houses, leisure centers and hotels along the western shore.
• What to bring: sunscreen, water, tenge cash for private beaches and restaurants.

How to get there

The reservoir is easily accessible from Almaty. Several routes exist depending on which area you're visiting:

• Western shore and Qonaev: A-3 highway heading north, where beaches and resort facilities are concentrated. Allow approximately 1 to 1.5 hours depending on traffic.
• Northern shore: A-3 then branch onto a secondary road leading directly to the waterfront.
• Ili Delta (wilder zone): A-351 road toward Shelek, then heading up to the delta.
• Southern shore: exit A-3 then the Iliysky tract, renowned for panoramic views and water sports.

For public transport, buses depart from Almaty's central Sayakhat bus station.

What to combine in the region

The reservoir fits naturally into a circuit around Almaty. To the east, Almaty Nature Reserve borders the shore; to the north, Altyn-Emel National Park and its Aktau mountains host singing dunes and colorful ridges. Further east, the Charyn Canyon offers spectacular eroded rock formations, and Kaindy Lake completes a nature loop. For another major Kazakh lake, Alakol Lake, further east, deserves a separate detour.
