An usuually dry winter brought drought and crowding and hence avian cholera to wintering birds on the Klamath NWR. You can read about it here.
One problem is that the Klamath Basin has too many water users for the water available when rains aren’t normal or come late, as they have this year. The refuge birds do not get first call on water flowing out of Klamath Lake and eventually into the Klamath River.
