Weird water caterpillers with tails?

So my friend has a ”backyard pond” that gets cleaned at the begining of spring every year and that’s really about it. Its more like a cement hole with water. There is no fish or plants just water. Anyway, his 15 year old sun was cleaning the ”pond” out today and found these things that look like worm/caterpillars with a long thin tail. They wriggle in the water and swim slowly about. The smaller ones were close to the top of the 3 foot deep pond but the bigger ones started to come up when he had removed half the water. Can you help us identify them?

Dear Shellin and Damon,
These are Rat-Tailed Maggots, the larva of the Drone Fly. They are often found in stagnant water and the “tail” is actually a breathing tube.
