text: if you look at the bing z20 aerials west of here, compared with pre-construction imagery, you will see two points at the edge of the housing, where the mostly-dry stream goes undrground, plus an access.
  
  so the stream has been diverted underground, maybe along this imported path, maybe close to it.
  
  at the least, tag the entire length through the entire developed area as underground and intermittent.  the lake in this neighbourhood should disappear.
  
  it is hard from afar to guess how much the earthworks changed the previous path, or whether now it just serves to the west as drainage, all underground.
