- Comments:
- An estimated total of Klamath Basin with no specific location. This is a very large region so no coordinates provided nor entered here. Klamath Basin is an important region for grebe breeding and the adult numbers represent 5% of Clark's grebes and 15% to 30% of western grebes of their North American population at the time. The Central Subregion had 70% to 80% of the western and Clark's grebes surveyed in 2003 and 2004. This region includes the Upper Klamath Lake area, Sprague River Valley, Klamath River, Spring Lake area, Yonna Valley area, and Gerben/Willow Valley area.

Comments:
Not a survey but just an entry of threats conveyed by John Vradenburg, Supervisory Wildlife Biologist for the Kilamath Basin National Wildlife Refuge Complex. He responded to our outreach to him that the Klamath Basin had really dire conditions in the last two years where there was the lowest amount of wetland habitat in known history due to lack of water.
