Las Vegas isn't the only "offender".
Here in SE Texas, we have Lakes Toledo Bend, Sam Rayburn, and a few other, smaller, dammed lakes.
A recent state congressional redistricting left Houston with a larger vote in the water rights battle. This was not long after a house vote to allow Houston access to more water failed to pass. I do not think it will be long before they are doing to us what has been done to Vegas.
