Portable water pump?
I need to learn if there is any sort of light-weight portable water pump that can be carried (backpack or whatever) and hooked up to hose lengths at the inlet and outlet.
I'm thinking of maybe something with a 2-cycle gasoline engine. Hoping there is something made that is 35 pounds or less in weight - when fuelled up. Are such pumps made? If so, is there a gneric term for this kind?
Lastly, do you know any brand names?

A lot depends on how much lift and speed you need. Harbor Freight has a little 1" pump that fits the general description. You do know that hoses and pipes are heavy?

Maybe this company makes one a bit heavier, but with more power (?)

The sizes of the hoses will need to increase to get more volume of water. Here is a larger pump but still of a manageable weight.

Small pumps 500 to 1000 GPH can be bought that operate on 12V DC at West Marine or any boat supply. Typically these are used as bilge pumps. Reasonably priced and portable. 
Try this:

I guess I'm a bit unclear about these 12-v DC driven pumps: Are they still lightweight if you have to carry a 12v power supply with the pump?
My need is to be able to clean out my creek-water collection tank twice a year. I have to clean out muddy water, and a bit of silty slurry at the bottom of the tank. And I have to walk about 250 yards to get to the site. Can't drive to it. And I'd be carrying the pump, and possibly a few tools (shovel, etc). Probably, though, I can leave the hose(s) on-site.
Due to these factors, I'd like something within about 35 pounds, if possible.

Could you use a siphon?
Or pipe run from upstream like they do in remote salmon hatcheries?
A riding lawnmower sized battery will run my little 12 volt pump for 8 hours. It pumps about 10 gal/min if the lift isn't more than about 5'.

The pumps weigh very little, a few pounds. The battery would be most of the weight. You can buy small batteries that weigh almost nothing. How big is your tank?

Should you not be more interested in the gallons the pump can handle as compared to what it weights?

The tank is about 45 years old, and is an oldish design. It's what's called a "settling & division tank" and it is not constructed to hold a large amount of standing water. Its capacity is 500 gallons. It collects silt in one part - and a shovel can be used to help with getting the bulk of this out. Also, the tank has a drain. The issue is the remaining (settled-out) silty sludge, so the technique will be to keep re-introducing fresh water into the lower portion of the tank while stirring the sludge and pumping it out - repeatedly, until the tank is clean enough.
I'd want a reasonably capable pump, but also one that can be carried readily to the site.

This one weighs 40 lbs and will pump what you want

Could you transport it on a cart of some type?

There is a small pump that is made to go on one of those bottles for bottled water, the kind they deliver. If I remember corectly it takes 2 D batterys. the whole thing is made out of plastic.

Wheelbarrow to carry things in or a PTO driven pump off a small tractor seem to be your best bet.
