Assessment of Ecological Health of Tilyar Lake, India

Abstract

Tilyar Lake in Haryana is selected for the purpose of assessing its ecological health. A multi-index system has been used to assess the ecological health which includes Carlson’s Trophic State Index (CTSI), Simpson’s Diversity Index (SDI) and Water Quality Index (WQI). The results indicated that the lake health is average but is approaching to bad condition as indicated by EHI of 2.93. Suitable conservative measures should be adopted to arrest its further degradation. Certain conservative measures are also suggested.
