Comments:
Trost is observor but this is not in Trost paper. One nest is doubled to estimate # of breeding grebes though unclear how it's known as Clark's. Unknown survey type. Conducted as part of Western Colonial Waterbird Survey (WCWS), a breeding survey of 18 species from May to July 2009 to 2011, resulting in this Atlas.

Comments:
Trost is observor for May 26 survey, the only direct count of breeding birds in this set of surveys. June 1 through June 20 and June 28 through July 19 surveys are by Weinandt/Pfaff. June 23 survey is by Hugo. Except for May 26 survey, the rest are nest counts doubled to estimate # of breeding grebes though unclear how they're determined to be Clark's. Conducted as part of Western Colonial Waterbird Survey (WCWS), a breeding survey of 18 species from May to July 2009 to 2011, resulting in this Atlas.

Comments:
This entry to capture Colleen Moulton's (IDFG) comments on which breeding lakes might still be active. "Here’s a list of those that I know have had breeding birds in recent years: American Falls Reservoir, Blackfoot Reservoir, Cave Lake, CJ Strike Reservoir, Island Park Reservoir, Lake Pend Oreille, Market Lake WMA, Mud Lake WMA. These are all fairly small colonies (although Mud Lake used to be sizeable). There may be others, but I’m less familiar with/have less documentation of them."

Comments:
General statement that Western grebes nested in Cave Lake and other Planning Area lakes in "recent years" with no details. Estimated here as mid-2010s due to publication year of 2018. Also acknowledges water level manipulations that maintain deeper water may benefit grebes in general, no grebe species named.
