The site was identified as important in 2007 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Red-crested Pochard Netta rufina	LC	passage	2005	14,300 individuals	A4i
Common Pochard Aythya ferina	VU	passage	2005	40,100 individuals	A4i
Ferruginous Duck Aythya nyroca	NT	breeding	2001-2005	25-61 individuals	A1
Great Crested Grebe Podiceps cristatus	LC	breeding	2001	580 individuals	A4i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2017) is shown below.
