This study investigates the use of zooplankton as bioindicators to assess the water quality of Nagpokhari, a historic pond in the Kathmandu Valley. Zooplankton are sensitive to environmental changes and can provide valuable insights into aquatic ecosystem health. Systematic sampling was conducted over a period of [study duration], and zooplankton species were identified and quantified. Water quality parameters, including pH, dissolved oxygen, temperature, and nutrient levels, were measured concurrently. Our findings revealed a correlation between zooplankton community structure and water quality indicators. The presence of specific zooplankton taxa, such as [example taxa], indicated varying levels of pollution and nutrient loading. This study underscores the importance of using zooplankton biomonitoring as an effective tool for assessing and managing water quality in urban aquatic ecosystems. The results contribute to the development of sustainable management practices for Nagpokhari, ensuring its ecological integrity and cultural significance are preserved.
