In this study, observations were carried out in the surface waters of Saraydüzü Dam Lake within Sinop provincial borders for 1 year to determine water quality. The basic 28 variables used to determine water quality were measured monthly at six stations. Taking into account the World Health Organization's drinking water standards, the water quality index (WQI) and Turkey's Ministry of Forestry and Water Affairs Surface Water Quality Regulations (SWQR) were used in determining the water quality. In addition, irrigation water quality was examined. For this, sodium absorption rates (SAR), sodium percentage and residual sodium carbonate (RSC) values were calculated. WQI values in the lake were found to be between 17.62 and 29.88. Water quality parameters did not exceed the recommended limit values in all months and at all stations. According to these values, the Saraydüzü Dam Lake water belongs to the 'very good' class in terms of drinking water quality. The results obtained showed that there were no nitrogen or phosphate inputs that could harm the ecosystem in the lake and that there were no low/insufficient ambient oxygen conditions resulting from excessive oxygen consumption during the degradation process of organic matter. All water quality parametres are well below the permissible limits except some heavy metals according to SWQR. Cu, Zn and Fe were found to exceed the limit values. The water quality of irrigation water was found to be good in terms of SAR and sodium percentage, whereas RSC was observed to have varying qualities during the year and not be suitable for irrigation in some months. According to results of factor analysis (FA), pH, temperature, electrical conductivity, suspended solid matter (SSM), biological oxygen demand (BOD), total hardness (TH),total alkalinity (TA), calcium, nitrate, ammonium, mercury and dissolved oxygen are the main variables responsible for the processes in the ecosystem.
本研究对锡诺普省境内的萨雷兹湖（Saraydüzü Dam Lake）表层水进行了为期 1 年的水质观测。在 6 个监测点，每月测定 28 项基本水质参数，以世界卫生组织（WHO）饮用水标准、土耳其林务局和水资源管理局（Forestry and Water Affairs）地表水质量规定（SWQR）的水质指数（WQI）为指标，对水质进行评价。此外，还对灌溉水质进行了研究，计算了钠离子吸收率（SAR）、钠离子百分比和剩余碳酸钠（RSC）值。研究发现，该湖的 WQI 值在 17.62-29.88 之间。所有月份和所有监测点的水质参数均未超过建议限值。根据这些数值，萨雷兹湖的水质在饮用水质量方面属于“非常好”级别。研究结果表明，湖中没有可能危害生态系统的氮或磷输入，也没有因有机物降解过程中过度耗氧而导致的低/缺氧环境。除了 SWQR 规定的一些重金属外，所有水质参数均远低于允许限值。Cu、Zn 和 Fe 超过了限值。SAR 和钠离子百分比方面，灌溉水质良好，而 RSC 则在一年中表现出不同的质量，在某些月份不适合灌溉。因子分析（FA）结果表明，pH 值、温度、电导率、悬浮固体物质（SSM）、生化需氧量（BOD）、总硬度（TH）、总碱度（TA）、钙、硝酸盐、铵、汞和溶解氧是影响生态系统中各种过程的主要变量。
