After its perfect in 1936, the Hoover Dam has been among the largest and most important hydroelectric tree in the world. The approximately 4 exchange rate kilowatts of power it generates offers power come Nevada, Arizona, and also California (via bureau of Reclamation).

Local agriculture would experience from the lose of water, causing the hazard of fixed starvation. While simple to assume, las Vegas only recently started to take it in strength from Hoover Dam, having previously sourced electrical power through other way (via famous Mechanics). The lights therefore might shine for a little while longer.

However, even if it to be 100% self-sufficient, the loss of hydroelectric strength in surrounding locations could lead to the Vegas electrical grid being diverted to them. 

This would certainly certainly result in at least partial blackouts because that the city. The effects of no water (which primarily originates from Lake Mead, a reservoir created by the Hoover Dam), food, or air conditioning in the center of a warming desert could result in a massive number of refugees.
