Thanks for that info. The corkscrew is a beautiful plant so I hope it does well and is only dormant. The plant that stayed green this winter and never grew up to the water surface (that looks similar to a narrow leaf pondweed) looks like it would be a valuable oxygenator in the winter and a desirable plant to have. As the water level dropped in my pond last summer this plant always stayed below the surface so I want to double check to see if this happens this summer then I will take pictures and try to make a true identification of it.
