Putting ponds in the desert..or anywhere is going to take a lot of water due to evaporation. The recovery rate is going to be really low. Right now the area they want to use to do this has zero extra water. It all goes to AZ and CA to support current AG and people.

The prototype plants I have seen are not open cycle. In fact you need to go to great lengths to keep the cycle closed to keep the algae strain pure. You don't spend millions of dollars developing a custom breed of algae just to let it go feral in a pond and get contaminated with natural algae.
In addition in a pond you are limited to atmospheric CO2 levels. But if you push up the CO2 the Algae grows much faster. So you take the output of a natural gas power plant, cool it and then dump the CO2 heavy output through the algae.
