Alternative 3 would solve the current problems on a long-term basis, without risking structural damage to the dam. It would obviously involve a lot of tunneling, but the sandstones at Glen Canyon are much softer stuff than the metamorphic formations at Lake Mead, where Las Vegas already bored a 3-mile long, lower elevation intake in 2015 that allows their municipal water system to continue diverting even if Lake Mead hits dead pool. The cost for the Vegas tunnel was $1.5 billion, but I could see the Lower Basin states chipping in for something like this on a cost-share with BOR if it guaranteed them more reliable deliveries under the Compact.Seems like they could do a combination of options 5 and 6 on a temporary basis until one of the more expensive options are undertaken. The most important considerations for all of the options are Authority and Funding and are likely to be the final arbitrars.
