Lake Lowell (aka Deer Flat Reservoir) is in southwestern Idaho 15 miles east of the Oregon State Line.  I visited in winter in the mid 1970s and saw a mass of Mallards paralleling the south shore that stretched for most of the lake's 10-mile length.  I subsequently learned that the lake was usually setting CBC national highs for Mallards in those years, with numbers counted by refuge personnel in the 500K - 600K range.  

I tried to census a mixed-icterid winter roost at Cheyenne Bottoms, Kansas in 1986 and came up with 800,000 birds. Redwinged Blackbirds were predominant, with Common Grackles, Brewer's, BH Cowbirds, a few Yellowheads.

Memory of the event is distant and foggy, but probably
the largest flock of non-Sooty Shearwaters I've seen in
Oregon was (at least) 6 figures Mallards, I think (?)
on the Columbia near or at Umatilla NWR. This was 
on a whirlwind day trip to NE Oregon with Dave Irons
& Fix in the late '80s. Not sure if this was a normal
concentration at that time, but certainly an exciting
spectacle that I still picture occasionally.
