锡尔河控制和北方咸海（第一期）项目将改善锡尔河流域的水力控制，增加河流容量，增加流向三角洲和北方咸海的水流，从而维持和改善农业和渔业生产。虽然该项目将主要有利于恢复生态系统，从而改善微气候和空气质量，但负面的环境影响主要是水质恶化，以及由于NAS流入的中断而导致的三角洲湖泊干涸，同时对渔业产生影响，海平面波动可能会推迟基础设施的建立，渔业和旅游业的发展。本环境评估包括以下缓解措施。应保持严格的用水纪律和管理做法，包括提高水价，安全处理污水排放;此外，还将研究潜在的排水用途。在贝格海峡上建造一条堤坝将稳定水位，并有助于降低NAS周围的盐度。在锡尔河三角洲建造和修复堰，应能改善从供水渠到湖泊的取水口，地方灌溉应能保护农田免受洪水侵袭。
The Syr Darya Control and Northern Aral Sea (Phase I) Project, will improve the hydraulic control of the Syr Darya basin, and of increased river capacity, and water flows to the delta, and Northern Aral Sea (NAS), thereby sustaining, and improving agricultural, and fish production. Although the project will be mostly beneficial in restoring ecosystems, which in turn improves micro-climate, and air quality, negative environmental impacts feature the deterioration of water quality, and dried delta lakes, resulting from discontinued inflows from NAS, with concomitant impacts on fisheries, aggravated by the fluctuating sea levels which may potentially delay the establishment of infrastructure, fishing industries, and tourism development. This environmental assessment include mitigation measures as follows. Strict discipline in water consumption, and management practices should be maintained, including improved water pricing, and safe disposal of polluted water drainage; in addition, potential drainage water uses will be researched. Construction of a dike across the Berg Strait will stabilize water levels, and contribute to reduced salinity levels around NAS. Construction, and rehabilitation of weirs in the Syr Darya delta, should improve water intakes from supply canals to the lakes, and, local embankments should protect agricultural lands from flooding.
