The cause of the Buena Esperanza stream converges towards the lagoon. This, added to the closure of the bay, has completely reduced the salinity of the water, so in winter it used to freeze.

Creation story:

In 1944 began the construction of a passage of 600 m long by 20 wide on a sector of Ushuaia Bay, with the purpose of joining the old airstrip with the city, gaining a lagoon aspect. The work was initiated by the prisoners of the prison, and then by personnel of the Naval Base in 1950, since the prison closed in 1947. In the bay the cause of the Buena Esperanza stream flows along with some sewage drains. This situation produced both the decrease of the salinity of the water, allowing its freezing in past winters, as well as its contamination. For this reason, in 1993 the opening of two channels in the passage that allow an exchange of water and sediment, with the open sector of Ushuaia Bay. Currently, a project is underway to finalize its final cleanup. On the initiative of a group of neighbors, in 2009, the bay was declared an Urban Natural Reserve, by municipal ordinance No. 3631. The administrative entity is the Municipality of Ushuaia.
