I have no experience with C250 maintenance, but will offer my suggestions, for whatever they're worth, since you haven't received a reply yet. I currently have a Cal 25 that was taking on a lot of water inside the cabin recently. I threw a bucket of water into the cockpit and saw that the cockpit drain ran into the cabin and out through a thru hull fitting. The hose was badly cracked, and that's where the water was coming from.
If you turn a hose on the place where the water is probably intruding, you might be able to see where the water is coming in. A close examination might reveal a gap in a gasket or weatherproofing material, or perhaps a prior owner has even removed it.
I expect that the lockers have a channel around the perimeter of the lid that is designed to drain water. Sometimes those channels can become clogged with leaves or debris, and when a large volume of water is suddenly dumped on the lid, it can't drain quickly enough and spills into the locker.
The general approach is to find where the water is coming in, then examine the area to find what is allowing it to come in at that location, and then the remedy will be obvious.
Good luck!

I don't remember which boat this was on, but I had a similar problem with heavy dousing while washing a boat. I found that a hatch had a foam strip on the top of the ridge around the gutter, but that there was no foam at the hinges. A splash from a bucket or blast from a hose could find its way in there. I bought some thin, low-density weather-stripping and attached it to one half of each hinge, and that was that. Often it's something simple like that--sometimes not.

I have the same problem. I'm not being facetious here... I just have to sponge them out. I keep dock lines to starboard, but I also fill that locker with bags of ice as the resupply for the coolers. It does melt... but not too fast... better than not having them at all... but the locker fills with water. I just have to sponge it out at the end of the voyage. I throw the ducklings on the cabin floor to dry out before the next sail. I'm in a super dry climate, I wouldn't do it this way if I were still sailing in TX...
I look at the geometry, no real way to drill a drain hole. It will either be too high if drilled to drain to cockpit floor, or you have to drain into the aft "cabin" with resulting plumbing requirements. Too much hassle... so I swab...
