Milk Creek Project: Live Willows Added

Work today consisted of beginning to build up the roughness of the structure, because more friction means less erosive energy for flowing water. This design begins with base logs, on top of which are placed logs with roots attached. Then angled cross-logs are inserted, along with vertical posts. Adding slash from the tops of trees plus fill with plenty of cobbles helps consolidate the material and adds even more roughness.

Several clumps of live willow were salvaged and reused today, plus quite a few thick willow cuttings were placed to help develop a living, flexible root structure that will help bind material in the engineered log jam, add more roughness, and provide habitat benefits.

The contractor will be back on site next Tuesday, so expect a new batch of construction photos on Tuesday night!
