Around here, there are storm-water "creeks" everywhere; some of them have a trickle all the time, but most are pretty much dry unless there's a lot of rain -- we have one of the latter behind our house; 95% of the time, it's perfectly dry, just a gully with some big rocks... but a culvert leads to it, from the next street "up"... it runs down into another culvert and disappears somewhere still lower. Also huge catchment basins; some have a bit of water all the time, which gets progressively greener with algae, during dry spells, but after a big rain, they get more full, and very muddy. There's a "lake" (actually it's a pond but the engineers felt generous I guess) right beside the road my husband's company is on ("Lakes Parkway"), and back in '09 when we had LOTS of flooding going on, that entire road was under water at one end; you had to go around and come in the other end, to get to his work.
