Peñas Blancas dam cleanup will cause flucuations in river

The electrical generating company will be cleaning the dam at the Peñas Blancas hydroelectrical plant in San Ramón and has issued a warning that the flow of the river will be affected.

The electrical generating company will continue biological monitoring projects like this one during the cleaning of the dam area, which will put a lot of sediment into the river.

The work is scheduled to start today and continue through Sunday.

The river level is expected to rise at times to the same level that a strong rain might produce, said the company, the Instituto Costarricense de Electricidad. It urged residents not to take chances with the river.

The plan is to eliminate sediment due to human activity, landslides and rains.

The company has been making contact with residents in the nearby communities of Boca Arenal de Cutris and San Isidro de Peñas Blancas, it said. It also said that it would be making an effort not to damage the fish downstream.
The company maintains a continual biological program in the river as well as at other hydro sites.
