Which lake was built by stopping a branch of the local river, ‘Ruparel’?

Several well-known lakes of Rajasthan are artificial water bodies: a ruling family had a bund (embankment) constructed across a river or one of its tributaries to trap monsoon flow in this arid region. To identify such a lake, match the exact river named in the question to the lake whose historical construction record names that same river.

In 1845, Maharaja Vinay Singh of the Alwar princely state had an embankment built across a tributary of the Ruparel River at the foothills of the Aravalli range near Alwar city. The dammed valley filled with water and became Siliserh Lake, today marked by the lakeside Siliserh Palace built as a royal hunting lodge.

• Bal Samand Lake, in Jodhpur, was built around 1159 CE by Bal Rao Parihar and is fed mainly by rain and a supply channel from the nearby hills, not by any Ruparel tributary.

• Gadisar Lake, in Jaisalmer, began as a rainwater-harvesting reservoir for the desert city and collects monsoon runoff through masonry channels, with no connection to the Ruparel basin.

• Lake Pichola, in Udaipur, dates to 1362 CE and was enlarged by Maharana Udai Singh II; it is fed by Aravalli catchment runoff and the seasonal Sisarma river, again unrelated to the Ruparel.

Because only Siliserh Lake's construction record cites an embankment across a branch of the Ruparel River, the correct answer is Siliserh Lake.
