Probably an early flare due to the optical illusions of landing on smooth, unmarked water (well-known issue for float-plane pilots). It is very hard to judge height in such conditions.
Note that due to the gear being up, there were no audible altitude call-outs, just "Pull Up! Terrain! Pull Up, Terrain!" Visual judgement was all that was available.
