Morphometry and Bathymetry of Lake Cadika: A Comprehensive Study of Medan Johor District's Freshwater Ecosystem

Introduction

Lake Cadika, an artificial lake located in Medan Johor District, Medan City, is a vital freshwater ecosystem that plays a significant role in maintaining environmental balance and providing various benefits for the surrounding community. The lake's morphometric and bathymetric characteristics are crucial in understanding its physical condition and water quality. This article aims to provide a comprehensive overview of the morphometry and bathymetry of Lake Cadika, highlighting its importance in sustainable water resource management and conservation.

Morphometry of Lake Cadika

Morphometry is the study of the shape and structure of water surfaces, including the measurement of its area, length, width, and depth. In the context of Lake Cadika, the morphometric data obtained shows that the lake has an area of approximately 30,887.21 m², with a maximum length of 386.62 m and a maximum width of 150.01 m. The length of the lake reaches 1,681.08 m, with an average depth of 1.63 m and a maximum depth of 2.60 m. The average slope of the lake is 7.33%, indicating a relatively gentle slope.

Bathymetry of Lake Cadika

Bathymetry is the measurement of the depth and basic contour of a lake. In the case of Lake Cadika, the bathymetric data obtained shows that the lake has a significant volume of water, approximately 52,377.46 m³ or equivalent to 52,377,460 liters. The measured water residence time between 194 to 195 days indicates high stability, which is essential to support aquatic life and water use by the community.

Water Quality of Lake Cadika

In addition to morphometric and bathymetric aspects, water quality is also a crucial focus of research. The physical and chemical parameters measured include an average temperature of 29 °C, Total Dissolved Solid (TDS) 36.47 mg/L, and Total Suspended Solid (TSS) 9.66 mg/L. Water brightness recorded 0.55 m with electrical conductivity (DHL) 72.93 μmhos. The pH value of water is 7.5, indicating neutral conditions, while phosphate levels (PO4) and nitrate (NO3) are recorded at 0.056 mg/L and 1.6 mg/L, respectively. All of these parameters indicate that the water quality in Lake Cadika is still in good condition, which is essential to maintain the lake ecosystem and support life in it.

Data Processing and Analysis

Through data processing using ARC MAP software, researchers can describe and analyze the characteristics of Lake Cadika more precisely. The results of this study are expected to be a reference for the management and conservation of water resources in the area. With a good understanding of morphometry and bathymetry, sustainable management steps can be applied to ensure that Lake Cadika can continue to function as a source of life for the surrounding community and natural ecosystems.

Conclusion

The morphometric and bathymetric study of Lake Cadika provides a comprehensive picture of the physical condition and water quality of the lake. This knowledge is valuable in efforts to manage sustainable water resources, support local ecosystems, and improve the welfare of the community around the lake. By keeping the lake in good condition, we not only protect the environment but also ensure long-term benefits for future generations.

Recommendations

Based on the findings of this study, the following recommendations are made:

Regular monitoring: Regular monitoring of the lake's morphometric and bathymetric characteristics, as well as water quality parameters, is essential to ensure that the lake remains in good condition.
Sustainable management: Sustainable management practices should be implemented to ensure that the lake's water resources are used efficiently and effectively.
Community engagement: Community engagement and education are crucial in promoting the importance of lake conservation and sustainable water resource management.
Research and development: Further research and development are necessary to improve our understanding of the lake's ecosystem and to develop effective management strategies.

By implementing these recommendations, we can ensure that Lake Cadika continues to function as a vital freshwater ecosystem, supporting the surrounding community and natural ecosystems for generations to come.
