First time out of the vault

In New Vegas when talking to Chief Hanlon, he talks about lakes that have been drained when asked about Lake Mead. He mentioned a lot of different lakes that were drained and I couldn't help but notice that one of the lakes he mentioned was not Lake Tahoe. In case you don't know, Lake Tahoe is a lake outside of Reno IRL. I went on the Fallout wiki and noticed that New Reno wasn't part of the NCR. Why is that? New Reno itself is a big place with lots to offer to the NCR including water. New Reno doesn't appear to have been affected by the nukes so Lake Tahoe should be perfectly fine. Tahoe is a big lake and NCR went to full on war to take Lake Mead and the Dam(even though they got power from it too.) which is tiny in comparison to Tahoe. With the benefits of New Reno and Lake Tahoe, why hasn't the NCR annexed it?
