A good deal of the standards from flat, wet states are modified quite a bit on waters that are man made like most of ours are. Some reservoirs have only been in their current state for less than 30 years, but even the ones that have been around for longer still have bottom structure that isn't typical for a lake that has been at a fairly constant level for thousands or hundreds of thousands of years. Not to mention the work that current from the rivers does and rising and falling water levels. On the other hand we have some reservoirs that are well situated to take a lot less direct sunlight than others and those freeze faster and better on average. Knowing the history of each of the reservoirs is somewhat important on early ice.
