Hanna Lake is a lake near Quetta city in Balochistan Province, in southwestern Pakistan. The lake is located a little short of the place where the Urak Valley begins and 14 km from Quetta. The reservoir was constructed during the British Colonial era in 1894,
and is one of the main attractions in the city.
Golden fish in the lake come swimming right up to the edge of the lake. There is a lakeside restaurant with picnic tables shaded by pine trees. At one end, the irrigation dam rises out of the depths like battlements of a fort, and on the eastern part the Hayat Durrani Water Sports Academy (HDWSA) the only rowing, canoeing, kayaking and sailing training center in Balochistan Province.
The HLDA / HDWSA and Merck has planted various trees for the beautification and protection of environment in Hanna Lake Mountains.
In 1894, the small action dam Surrpull (Red Bridge) was constructed on main Urak road for diverting of water into Hanna Lake coming from the Zarghoon Mountains range, of streams, snow melting and rains through main channel.
1990 Hanna Lake boat disaster
On July 6, 1990, 40 people were killed and 8 injured when an overcrowded boat capsized in Hanna Lake. Most of the victims were vacationers who were enjoying Eid-al-Adha holidays. Another boat was used to rescue the victims.
This channel nowadays needs repairs and is wasting water and recently the water level has become deadly low, up to three feet causing danger for thousands of fish. There is also a water channel which was constructed at the same time by the British to convert the snow and rain water near Spin Kaarez, coming from Murdar Mount, as surplus for filling the water in this lake. The channel was destroyed by a heavy flood in 1976 and has still not been re-constructed. The loss of the snow and rain water was wasted causing Hanna Lake to fully dry up between 1999 and January 2005. If the Hanna Lake Development Authority (HLDA), the custodians of Hanna Lake, do not take any measures to bring water through the surplus channel the lake will be soon dry again.
From year 2000-2010 Hanna Lake dried up and the natives along with hundreds of migrated birds were in trouble.
However, in 2011 the lake re-filled and once again gave rise to flora and fauna in its environment. The turquoise waters of the lake provide a rich contrast to the sandy brown of the hills in the background. One can promenade on the terraces or hire a boat and paddle on the lake and round the island in the middle.
