Urban lakes provide crucial ecological, social, and economic benefits, but rapid urbanization land use changes have significantly compromised their health sustainability. This study investigates the interrelations among use, temperature, water quality in Vellore (1997–2024) to address sustainable development goals (SDG) 6.4 (water) 13.3 (climate resilience). Satellite derived data revealed a direct correlation between reduced spread area (1.82%) increasing LSTs, underscoring adverse effects of urbanization. Notably, 64% dissolved oxygen (DO) samples surpassed permissible limits. Hardness, electrical conductivity (EC), total solids (TDS) DO emerge as primary influencers Water Quality Index (WQI). It was validated by XGBoost model. Based on WQI most lake classified “Poor” for drinking. Principle component analysis 68% variance with main factors LST, built-up, vegetative cover. Furthermore, suggesting that implementing 30% green buffers, restoring 2–5% WSA, adopting climate-smart urban planning could lower LST 1.8°C. These science-driven strategies align SDGs India’s Smart Cities Mission, offering pathway harmonize ecological resilience safeguard biodiversity under changing climate.
