Yes that is problematic. Lots of shallow water just begs to be filled up with aquatic vegetation.
When it comes to cleaning out something of that age, it is often just as economical to just build an additional pond, leaving the original one "natural" and being what it already is. But if the current pond is in a perfect strategic location, cleaning out might be the only option.
In our area we could just take a trackhoe and go around the outside and deepen what we could reach and help it a lot. I have done that to one very old pond on my place. But not all areas can do that without breaching the sealing bottom layer and creating a leaky pond. You would have to seek local advice about your soils before doing something like that. We have mostly solid clay we dig into.
