It is shown that by using a plain queue to fill depressions once they have been found, an O(m lg m) time-complexity can be achieved, where m does not exceed the number of cells n. This is the lowest time complexity of any known floating-point depression-filling algorithm.

In testing, the improved algorithm ran 6. 5 times faster than the old for a 100 x 100 cell flat and 69 times faster for a 700 x 700 cell flat.
