If the plants you want there are healthy, there is no need to do anything. Diverting water elsewhere will change the hydro environment of that place and where ever the water goes. That means whatever grows in these places (plants, soil flora, diseases, fungi, bacteria, etc.) will have to re-adapt. Sometimes to the good, sometimes to the bad.
Most plants in the North America are already adapted to an abundance of snow melt/rainfall in the spring and they actually grow best in that environment.
How do you get so much snow in north central Florida?
