The construction of the dam across the Markandeya River at Yargol in neighbouring Karnataka is likely to cast a shadow over the much-awaited Thenpennai-Palar river interlinking project.
If the Karnataka government holds back water at the Yargol dam, it will lessen the flow into Pennaiyar.
This will subsequently dim the prospects of the Krishnagiri dam receiving copious amount of water during the monsoon.
This will have an adverse impact on the areas of northern Tamil Nadu downstream.
Note
Thenpennai-Palar interlinking project envisages bringing 3 tmc water from Thenpennai river to Palar at Vaniyambadi in Tirupathur district.
The project would benefit Vellore, Tirupathur and Ranipet districts.
