U308 deposits under lakesPoo, if you research all the operating mines and all the deposits that are proposed mines in the Athabaska basin, you will be hard pressed to find one that is not affected by water. Have a look at Hathor and Waterbury, didn't affect there takeovers.
I have this all on my worry list for 2022 when I willl probably have Cameco shares after they buy FCU for $5.00 per share.
Best you look at buying shares in DEV's pot company. Then you can not worry and be happy!!!
