Boardman River Dam Update: 12/4

With the powerhouse now completely gone Molon Excavating redirected the river flow from the temporary diversion channel back to its original location where the powerhouse once sat. The river is now back where it once flowed for thousands of years prior to the construction of Brown Bridge Dam back in 1922.

This week Molon will begin the tedious task of dismantling the dewatering structure to determine what factors contributed to the breach on October 6th. Representatives from all parties involved including the MDEQ who is leading the investigation have gathered to witness and document what they find.

Molon also continues dredge the fine organic material that has accumulated just upstream of the former dam. They expect to be done dredging by mid-December. Once this is done the river is expected to clear up significantly.

Lastly, workers installed wood along nearly 800 feet of the new river at two locations where the river bumps up against the access road at the bottom of the steep north bank. The wood is from the tops of oak trees harvested near Ranch Rudolf and Rennie Lake roads. AJD Forest Products donated the wood and proceeds from Rotary’s Gourmet Game Dinner helped pay for the trucking. The City will decide for sure this month but will likely keep the access road at the base of the steep north bank as a recreational trail.

As always please let me know if you have any questions.
