There are 14 people waiting for a bed in Letterkenny University Hospital, according to the Irish Nurses' and Midwives' Organisation.
Yesterday's figure for LUH was 24.
The nurses' union today claims there are 12 waiting on trolleys and two in wards at LUH.
Nationally, the INMO claims the figure is 649, compared to a record-high of 714 yesterday.
University Hospital Limerick's figure of 58 is said to be the highest in the country today.
The INMO publishes figures every day in its Trolley and Ward Watch report to highlight the issue of overcrowding at hospitals across Ireland.
The HSE produces its own figures and these typically to do not tally with those of the INMO and are usually lower.
The HSE today claims the LUH figure is 11 and the national total is 476.
Unlike like the INMO's figures, the HSE's TrolleyGar figures do not give the number of patients who have been placed on wards, but are waiting for admission for a bad, having already been admitted from an emergency department.
The INMO report counts the number of patients for whom a decision to admit has been made, but who are still waiting for a bed at 8am.
It records those patients who have been moved to wards or onto trolleys but who are still waiting for a bed.
These patients, who are regularly categorised as being “on trolleys”, have not been allocated a ward bed, and typically have to wait along corridors but are also moved between general locations where space allows.
