Bau Tro - Green Lake on the Sand

Standing on a sandy hill of Hai Thanh ward to look down, we can see that sea and lake only a few inches apart. in rougt sea days, just think that the sea integrates into the lake. Strangely, despite nearly, the water lake is still fresh as the forest streams. Formerly, Dong Hoi denizen often taking the water lake to washing white clothers. Lake water seep mainly from the sand so very cool and saccharine, can bleach clothers. This is the only fresh water source provide running water for denizen of the city which was contaminated with salt water for a long time ago. 

Surrounding the lake is the range of green casuarina trees emerging on the blazing sandy zone. In recent years, as the ecological lake environment has improved so many birds return to reside in forest. Visitors to the lake, nothing interesting than tie the hammock under a tree and listening to rustling of sea wave mixed the chattering of birds that take us to peacefully sleep. 
In summer, when water levels shallow about a third down, the lake looks like a giant left foot mark. Locals still tell many legendary stories about this lake that is so deep that no bottom. Formerly, someone threw a grapefruit into the pool, then grapefruit Sen emerged in Sen Lake of Le Thuy District. Perhaps this legendary stories to tell that the water source never dry, even in many months of hot summer.
