After all the rain in December, the pond got very murky. It eventually cleared up, but the stream flow had slowed to a trickle from when I first installed it. I figured the filter box must be clogged up with the sludge, and when I took it apart, I was right. But I cleaned it all out, and put it back in. But now the problem seems worse. Is there a failure mode for a submersible pond pump that would result in not zero, but low flow?

Tube kink or tube connection just loose enough to allow high-pressure water to escape. I occasionally have both problems.
Pretty sure that’s not the problem. It’s probably the impeller. I won’t check it until tomorrow, because we’re getting some much-needed rain today.
The easiest check is to take the pump out of the filter box and see how it does. A couple of times I’ve had to open the pump and clear something from the impeller. There can also be damage to an impeller but those are pretty cheap to replace.
OK, so actually dismantle the pump itself. I guess I can do that.
It should be fairly easy to take it apart. Usually some screws and perhaps then rotating the impeller housing if it’s also using slots and tabs.
Youtube might even have a maintenance video for your particular brand, though they’re all pretty similar.
Some of your northern readers might also be having pond pump problems, but that would be due to ice and slush.
Agree with cleaning the pump itself. Mine used to get clogged up, but simply open the housing and pull out the impeller which has a magnetic drive. Yours may be different, but worth a look.
