your query is missing some stuff!
"select *
Mainly how the two tables are linked.  Now, if you want all the data from both tables, try:
Select * From wwscada.VaTfLt.dbo.FlowDaily
Select * From scadaaldb.AlTfLt.dbo.FlowDaily
You need to do the link command at the server level, i.e.

If your SQL servers as sql1 and sql2, and you want to run statements from Sql1 linking to sql2, execute this on sql1

exec sp_addlinkedserver sql2  (or exec sp_addlinkedserver [sql2\instancename] if instanced)

Now, the trick is that the current login should work equally on the other server, whether Windows or SQL login/pass.  Otherwise, look up BOL for sp_addlinkedsrvlogin

The above is a one off to link the servers together.
Then, you just run the select normally

select *
from wwscada.VaTfLt.dbo.FlowDaily
join scadaaldb.AlTfLt.dbo.FlowDaily on ......
