Dozens of Haitians work to reinforce river beds in simple conditions armed with rudimentary tools and often barefoot.
The work is hard, but it brings in much-needed money and prepares the community for the rainy season.
Along a stretch of riverbank almost a kilometer long, 10 teams of 20 people perform the same exhausting actions, turning over soil and extracting rocks under the boiling sun as they stand in muddy water.
But they work with smiles, and some even sing, appearing happy to be among the thousands in quake-devastated Haiti participating in "Cash for Work" programs.
The men and women are residents of Leogane, a town some 40 kilometers (25 miles) west of Haiti's capital Port-au-Prince, much of which was destroyed by the January 12 earthquake.
For them, the labor presents a double opportunity: the chance to earn four or five dollars a day, while working to ensure that the large canal that often floods their homes -- and this year threatens their tent refuges -- will not overflow.
Gabriel Sanon has abandoned the land he farms to participate in the program for 20 days. In the three weeks employed in the program under the auspices of Acted, a French non-governmental organization (NGO), he stands to earn as much as he ordinarily would in three months.
"When the rain falls, there are a lot of problems," the 25-year-old father adds.
For Franky Jean Simon, 28, a bricklayer and goat farmer, the incentive is only partly financial.
