Another trap with water landings is judging your height above the surface, especially on flat glassy surfaces. In this case extra speed might be a good idea with a flare slightly higher and gentle descent as speed washes off to touch down. Once you start making contact firm backpressure as it slows will minimise the chance of flipping, ie don't relax until it stops.
Also knowing which way the current is flowing can minimise impact speed. Ideal would be into wind but with the current...
