Tenis (ru|Тенис), is a lake in the southern part of the West Siberian Plain, Omsk Oblast, south-central Russia.[1]
The lake is an Important Bird Area,[2] especially for the Dalmatian pelican, and is part of a 30000ha protected area.[3] The name is probably from teŋiz, the Siberian Tatar word for "sea".[4]
The waters of Tenis are fresh. The western section of the lake is also known as Saltaim. Both parts are connected by an over 2km (01miles) wide sound. The Tenis-Saltaim lake is the largest of the Krutinka Lake group.[5] The Ust-Logatka and Ust-Kiterna settlements of Krutinsky District are located by the lake. The Osha river flows across Tenis and minor rivers such as the Karasuk, Balka-Sukhaya and Tleutsay flow into it. The shores are generally low, they are marshy in some places. Very close to the north lies a cluster of smaller lakes, including Synkul, Kalykul, Sazykul, Gorkoye and Achikul.[1]
Lake Ik, the second largest lake of the group, is located nearby to the southwest.[6] [7] [3]
Among the fish species found in the waters of the Tenis/Saltaim, crucian carp, pike, zander, perch, bream and carp are worth mentioning.[8]
