Olympic 1-WSP

Add a larger pooling finish at the end of a meandering stream or a cascading waterfall and "complete the look" of a natural water feature. This is the perfect kit for large-scale landscapes requiring a midrange stream length with a moderate size vanishing pool.




Stream Size:

4 feet wide x 37 feet long


Vertical Drop:

Up to 10 feet

Pooling Finish:

3" deep 70 sq. ft. pooling area

What is Vertical Drop?

Vertical Drop is the combined height of the system's waterfalls. For example if the system has four two foot waterfalls the total vertical drop would be 8 feet.



Design Notes:


  • The length of liner included with each kit is longer than the stream to account for vertical drop and turns in the stream channel.
  • The stream width of 4 feet mentioned above is the width of the stream channel before adding rock.
  • The gravel depth over the liner is based on 1-1/2 inch of gravel over the bottom of the liner.
  • The depth of water over the gravel will be approximately 3/4 of an inch.
  • A valve to adjust water flow is included with each kit.
