Ive seen similar setups here in Texas for quail. In my opinion, any dependable fresh water source is good for all wildlife.
The only change I’d suggest is putting some kind of overhead brush and wire screen to help minimize predation from raptors (hawks, eagles, owls, etc). Drive 4 t-posts in a large rectangle and run a smooth wire at the top of the posts to make the perimeter. Then secure chicken wire or a welded wire cattle panel on the smooth wire with zip ties or fencing wire. Then lay branches on top of the panel/chicken wire. It’ll give shade to minimize evaporation of the water and keep raptors from snatching pheasants and quail while they’re drinking.
