My pond was finished on 4/2/19 and I put down a mix called "pond/tank damn seed" its goes for about $4.00 a pound. I got lucky and it rained about once a week for it only water. I have a pretty good stand coming up, so I hope we get some rain once/twice/more a week. The damn is mostly clay, so I'll keep my fingers crossed. I went out there on 4/26/19 and the pond was dribbling over the main spillway. 1/2 acre pond filled in 24 days, I might just buy a lotto ticket
