An investigation was made on the Haizda Embankment project in the Haor area of Netrokona district to evaluate the goals and objectives of the project. Data collected from 50 farmers, 20 project staff, local government officials and expert through a structured questionnaire. Both pre-project and post-project situations were taken into consideration. The agricultural and social development were appraised on land use, use of seed variety, fertilizer use, water management, labour employment, yearly income of the farmers, land ownership, use of insecticides, transportation facility and educational changes. The pre-project and post-project scenario in the above mentioned aspects were statistically compared by means of t-test. Significant improvements in almost all the aspects were found at the post-project condition. On the other hand analyzing highest water levels of the area, it was found that the water level significantly increased outside the embankment after the project construction, which also increased the vulnerability of livelihood. At the same time fish production in Mohanganj Thana significantly decreased after the embankment construction and also decreasing rate is continuing. The fisheries ecology have been changed in the poldered area because of (i) free entrance of water is prevented at low flood level, (ii) the requirement and spawning ground of major fish species have been interrupted and (iii) decreased the opportunity of capture fishing in the project area. So, planners should consider the related adverse effects on nature and environment and its remedial measures during the planning of this type of small-scale water resources development project.
