That isn't an unusual size for a beaver.
Around this time of year in the spring one can often find beavers dead along highways. They seem large, and it is a bit of a shock to find out that
these dead beavers are yearling kits that have been evicted from their birth lodges by their parents, and they are searching for territories of their
own (which is why they are wandering on to highways and getting killed). That is to say that the apparently already large beavers are immature
juveniles, NOT adults, and that the adults are much bigger.
Wikipedia
Beavers continue to grow throughout life. Adult specimens weighing over 25 kg (55 lb) are not uncommon. Females are as large as or larger than males
of the same age, which is uncommon among mammals.
In fact, it was common for natives to use (single) pelts from adult male beavers as blankets.
So the beaver you saw was undoubtedly large, but not freakishly so.
It may not be a cryptid, but I'll certainly bet it will still be a great story to tell your grandkids about.
