Following the construction of the hydroelectric power complex on the Bukhtarma river about half a century ago, there have been gradual changes in the natural layout of the vast Chyorny (Black) Irtysh delta. As a result, the wetland network of previously seasonally flooded areas have been completely inundated, while a new delta structure has emerged in the higher section of the Chyrony Irtysh, submerging the previously dry tracts of the Zaisan Hollow. Presently, the delta extends, in its widest parts, up to 40 km east to west, and 30 km north to south.
Appreciation for the valuable information provided by local naturalist A.I. Karamyshev.
