Fish Passage Regeneration & Stream Restoration

If the watershed is in favorable condition, more then likely the stream is fluvial-geomorphologicly in balance which promotes overall stream health.  The reality is most streams have some form of influence by our intervention.  When this interference reaches a particular point, dramatic swings in stream health can occur. This can be caused be increased flow from urbanization, by watershed deterioration of botanical species, point and non-point source pollutants, or by physical obstructions or alterations to the stream channel. Biomass wasting, sediment transport, and organic replenishment, such as upstream fish passage, are also important elements to the contribution of stream health. 

Our approach, recognizes the elements that drive these mechanisms and uses techniques to establish "self-healing" to the stream as much as possible depending on the constraints of the site conditions.  At WW we use revolutionary fish passage navigation designs that go in hand with site specific stream channel restoration schemes.  We also engineer and build traditional and modified fish ladders when necessary, in addition to other fish guidance mechanisms including modifications and/or removal of  irrigation or dam structures and designs for fish screening.

Our techniques for stream restoration, such as our own bioengineering methodologies along with our unique approach, which breaks away from traditional contracting, greatly simplifies the implementation of such work.  Because of our hands on experience, we have developed methods that are relatively simple but yet functional.  But we also recognize that good ole’ Mother Nature is tricky, and sites have their on specific problems.  That is why we continue to develop and improve techniques we implement with new ideas in both design & construction of such restoration projects.
