Ticha Reservoir (Bulgarian: язовир Тича, yazovir Ticha) is a reservoir in Varbitsa Municipality, Shumen Province, northeastern Bulgaria, located to the north and northeast of the town of Varbitsa.

[2] Before entering the reservoir, the river gathers waters from the hilly Gerlovo region.

[7] The Ticha Reservoir's total volume amounts to 311,800,000 m3 (1.101×1010 cu ft).

Due to this, the water level of the reservoir is closely monitored and dykes have been built.

[9] In February 2010, the tap water in Shumen, which comes from the Ticha Reservoir, was declared unsuitable for drinking as a result of the presence of E. coli strains.
