If there's any head at all to that creek the proper tool for the job is a hydraulic ram.
You can make one out of a few hunks of pipe, some plumbing fittings, and two check valves. Lots of plans on the internet (and some references to them on this board.)
Once started (and they'll auto-start if properly configured) they'll operate for decades with no maintenance. They automatically trade flow for head as necessary to get the water up the hill to you.
So pump it up further - to a raised storage tank to both provide the operating pressure and to store the water as it is slowly pumped up and release it quickly when you need it to flush, run a bath, fill a sink, or whatever. The overflow on the tank regulates your pressure. (Be sure you have a good way for the extra water to go back to the stream or do something useful or decorative, rather than eroding your foundations.)
Three moving parts (plus the water, of course): The balls in the two check valves and a cotter pin or something jiggling around in the "snifter hole" to keep it from clogging so the "pressure dome" (yet another hunk of pipe with a pipe cap on the end) always has an air bubble in it.
