Thousands of flamingos migrate each year to nest in Lake Tinsilt, located around 450 kilometres (about 280 miles) southeast of the capital Algiers.
It is one of the largest wetlands in the country, with an area of more than 20 square kilometres.
"Barely a month ago there was water here," volunteer Mourad Ajroud told AFP on Friday, pointing to what is now a vast expanse of cracked earth littered with the carcasses of dead birds.
The disappearance of the lake, which locals and Algerian media attribute to high temperatures and a years-long drought, has driven the adult flamingos away.
They left behind their unhatched eggs and defenceless chicks, dozens of which have died from hunger, thirst, poaching and wolf attacks.
A group of volunteers provided their cars and trucks to transfer 283 pink flamingos about 50 kilometres away to Lake Mahidiya, about 50 kilometres away.
The wetland near Ain Mlila remains flush thanks to a steady flow of water from nearby rivers and lakes.
The rescue operation was initiated by local amateur photographer Tarek Kawajlia, who documents the wildlife in his area, and noticed the decrease in the size of the lake and the flight of birds.
The volunteers carry out "morning and evening patrols to follow the chicks until they recover and are able to fly, so that they can return next year to the sabkha (marsh) and life can resume its normal course," Kawajlia told AFP.
Ajroud, 53, said the group was not able to save all the birds.
"We couldn't transport them all," he said sadly, as another volunteer takes an injured bird to a veterinary clinic.
A few hours after the chicks were released at their new habitat, some adult birds joined them.
"The operation was successful and the parents found their little ones in a magnificent scene," Kawajlia said in a comment on one of his photos posted to Facebook.
Lake Tinsilt is one of the around 50 bodies of water in Algeria declared wetlands of international importance under the Ramsar international environment treaty to protect wetlands.
Last year, about a hundred pink flamingos died at Lake Telamine in western Algeria's Oran province due to wastewater pollution, according to environmental activists.
