More filters?

So we finally got our lake water system set up this season but were only able to use it for a few weeks before we had to shut everything down and evacuate due to an approaching forest fire. The system consists of a 1 HP submersible water pump that directly fills a 32 gallon pressure tank. From there it goes through a 50 micron sediment filter, a 1 micron paper filter and then through a charcoal filter. After that, the water runs up through a 3' long UV sterilizer and into the cabin. The only plumbing fixtures are a shower, bathroom sink and kitchen sink. We still use outhouses and everybody's fine with that. The system worked fine. Water pressure was good and the taste and smell of the water was decent.
When we removed the filters to shut the cabin down for the season and get the hell out of there, the 1 micron filter was completely brown after three weeks of use with 7 people staying in the cabin. I'm sure this is to be expected sucking in lake water but I am just a bit concerned that maybe we need to add a stage or two more, prior to the pressure tank to both do a better job of filtering as well as make the filters last longer. I'm fine with replacing them every season but this filter needed to be replaced now and we were planning to stay another week had we not been evacuated. Just wondering what others do to filter their lake water.

The first filter stage in our system has a valve at the bottom for flushing. Maybe I just need to add one or two more before the water hits the paper filter and flush them every week or so.
Just filtering the kitchen sink would be fine but we brush our teeth at the bathroom sink. After that you’re only left with the shower. Plus, we need to gravity drain the water lines every time we close shop for the season. Right now they are all plumbed to run down hill. Don’t want to refigure that out.
I like the gravel and sand filter idea but I need water faster than 7GPH.
The UV light stays on the entire time we are there, so water should be good as soon as it passes through.

In case anyone comes to this thread looking for the same info as I was. Russo makes a flushable 30 micron filter. I think I will place this after the 50 micron spin down I already have. I would think installing a valve on the inlet, shutting it off and opening the flush valve would force clean pressurized water already in the water lines backwards through the filter and out through the clean out. I think I’ll also throw a 50 micron before the pressure tank.

There's a larger, whole-house size with a 50 micron on the main line (everything except toilet) that I normally only have to change once per season. It's been getting clogged faster recently though, so my to-do list for today includes diving the submersible to see if it's moved or something to cause it to suck mud. Maybe you have a similar issue?
I think you can get smaller micron filters for the bigger whole house type housings. A bigger filter should last longer?
