Tengiz
General Information
| Description |
Lake Tengiz has no outlet, and is therefore salty. 295 species of birds have been recorded at Lake Tengiz, 22 of which are endangered. Uninsulated powerlines were killing numerous birds before a GNF project to replace the powerlines with a solar energy station. |

Watershed Management
| Description |
During 2001, Global Nature Fund (GNF) collected money to construct a solar power station at Lake Tengiz.
The project was carried out on-site by the Living Lakes partners NABU (German branch of Birdlife International) and the local national park authority Korgalijinski Zapovednik. The power lines that had been killing rare birds (see "Species of Concern" below) have now been removed.

| Species of Concern |
Non-insulated power lines caused the death of a large number of birds including very rare species such as the steppe eagle and the spotted eagle in the past. In 2000, 800 birds were killed on a stretch of 11 km in the space of only a few days. |
