By the look at your images , it looks like you had the water color set with nearly grey , so try this:
Change this line:
float3 WaterCol = { 158.0/256.0 ,168.0/256.0 , 198.0/256.0 };
To:
float3 WaterCol = { 158.0/256.0 ,148.0/256.0 , 148.0/256.0 };
Or change the water color from lua , use this command:
SetShaderVariable(0,"WaterCol", 158.0/256.0 ,148.0/256.0 , 148.0/256.0, 0)

If you like the DX9 water more , just use "#define OLDWATER"
