Freshwater diatoms of Anasagar Lake, Ajmer was investigated between July 2023 to June 2024. Samples were collected on the interval of for months and variation in flora was analyzed seasonally, including monsoon, post-monsoon, winter, and summer seasons. The range of Shannon diversity indices was found between 1.60 and 3.84, the species evenness between 0.37 and 0.66, and the Simpson’s diversity index between 0.022 and 0.22. The diversity indices indicated that there is light to moderate level of pollution in the studied sites, with moderate diversity level. This study suggested that the post-monsoon was more favorable for diatom growth, possibly due to nutrient availability. Sixty-two species of diatom were identified. Twenty-seven genera and sixty-two species represented these species.
