I have always wanted a pond but I would like each element that I add at this point to have a reasonable and practical purpose. Is there one for a pond? I love ponds and have always wanted one but am having a hard time justifying one for the amount of work that would end up going into it.
Also, if I go ahead with a pond, there will be no pumps or electric filters; how do people keep their ponds clean?
Thank you for the tips 
I don't know where to start! lol
Practical purposes for ponds:
1. Water storage / catchment in general
2. water for animals wild & domesticated.
3. Fire protection. (keep some buckets nearby, put out fires faster than with a garden hose)
4. Temperature and environment moderation, microclimate creation.
5. Emergency water for power outages (flushing toilet, bathing, etc)
6. Raising fish as hobby / food
7. Ornamental beauty.
Those are some practical purposes off the top of my head.
Justifying work:
The reasons above. Also, the amount of work is tied to how large the pond is.
I've hand dug and built small ponds by myself in two days that fill all of the purposes above.
There is a vast difference in the time and work to build a small pond 6-10 feet wide and 2-3 feet deep than a 1/4 acre pond.
Amount of work to maintain:
The bigger the pond, generally the less work. Larger ponds can better support aquatic life cycles and tend to self moderate better.
A smaller pond is harder to keep flora and fauna balanced- There would be more need to intervene (scoop out overgrowth of plants or filter the water if there are large numbers of fish,etc)
That said, I have a couple of small ponds, that are only 2-3 feet deep that really balanced and require almost no work beyond tossing a few pinches of fish food for the goldfish. Native
wood frogs (rana sylvatica) have colonized on their own and they eat any mosquito eggs. Floating surface plants keep algae from forming.
I had no pumps in these ponds until a neighbor surreptitiously added goldfish to them, and then only put in some cheap submersible pumps just to add a bit of oxygenation.
