TIDEWOOD-JOHNSON

Location:

The Tidewood-Johnson Park is located right off the Springwater Cooridor (SWC) bike trail just a short bit downstream from where Johnson Creek Blvd crosses at SE 45th. There is a convenient parking lot at this (East) end of the trail. Otherwise, by car the nearest access is probably from SE 37th or 39th.

The railroad tracks in the map (right) is the SWC.

 

Interesting points:

Along the corridor coming in from the east, you can see how Johnson Creek was channelized and has stone structures directing and changing the flow. In Tideman-Johnson Park the flow is allowed to go along much more natural banks. There has been an extensive amount of removal of invasive species (Him. Blackberry) and planting of native species.

 

Possible sampling points:

There are bridges and access points all along the Springwater Cooridor in this region of the stream. Just east of SE45th and Johnson Creek Blvd, Errol Spring contributes to the flow and chemistry.

Remember:

  • stay out of the restoration area (you are not on official business)
  • be very careful around the stream bank where it can be muddy, slimy and slippery
  • sampling points during dry times may not be accessible at high water especially in the restoration flood plain area
  • when the stream is up, the woody debris that you see sitting around in fall may be moving
  • see the other safety warnings
