Re: “Hunting Near Homes Rattles Residents

The obvious problem is the inadequate distance of 150 yards from private property or occupied public property that shooting is not allowed by federal law. This distance should be increased to one mile in order to provide for the safe use of firearms. One mile is the distance that the NRA stated that a .22 could be dangerous, back when the NRA cared about gun safety. 36 CFR 261.10 (d) (1) - Occupancy and use, needs to be changed to one mile. This has been an obvious flaw in public safety for decades and is the basis of the problems stated in this article. All other jurisdictions would automatically change to respect federal supremacy.

Re: “Bend Park and Recreation Adopts new Mirror Pond Resolution

Great report, thanks. I'm beginning to believe that this whole affair is just a land grab of the bed and banks of the Deschutes River and no one really has a clue how to save Mirror Pond. The pond is toast and it's just a matter of who owns what land when PacifiCorp bails out of town. They don't even list the Bend Hydro project on their website.

Re: “Northbound: White River Falls State Park

The iconic falls into the pool is call Celestial Falls, named by Matt Rutledge, the first kayaker to run the falls. This is the official name since 2014 (GNIS ID: 2770703)

Re: “City Says Mirror Pond Should be a Parks Project

Here's a clip from the 2013 dam inspection done by Roger Raeburn, P.E - Chief Dam Safety Engineer of PacifiCorp.

"The observations provide better knowledge than previously available regarding the mode of the severe leakage events experienced in 2008, 2009 and most recently in October 2013. The needle bay sections of the timber crib are the most vulnerable to deterioration, in particular the ceiling boards. As the internal components of the needle bays age and deteriorate, their ability to provide adequate support/restraint for the rockfill material is gradually lost. The loss or failure of a needle bays side facing board does not appear to be as critical as the ceiling boards. A ceiling facing board failure results in a release of the rockfill into the bay. The associated loss of support to the upstream facing boards due to the release of the rockfill results in greater stress loads in those upstream facing boards. As individual upstream facing boards fail, the loads are shifted to adjacent boards, increasing the stress level in them, causing them to deform further, and eventually fail. As this cycle of aging and deterioration continues, larger pathways for leakage are created leading to the loss of more rockfill (and its associated support), resulting in an increased number of upstream facing board failures."

The full facing of sheet-pile is only masking this deterioration to keep the dam's condition out of the news. Shallow water and the MPS land grab are the least of the problems in saving the Iconic Mirror Pond (IMP). The only thing dredging will achieve, besides polluting the river and wasting public funds, will be the reduction of expenses for PacifiCorp when they decommission the project.

Crossing your fingers and covering your eyes is not public safety.

Re: “The Food Cart Guy

Good for you and your family to recover. Be strong, that's what private enterprise is all about. You can become more than just your own success, you can be an inspiration for others. That will be your greatest achievement.

Re: “Making River Stewardship Habit

ALL the tubes should have a net bag. It's really gross to be surfing and see candy wrappers and beer cans float by.

Re: “A Ballot Measure on Mirror Pond?

The discussion about dredging Mirror Pond is a distraction from saving Mirror Pond. Mirror Pond is dependent on a dam and the deposits that have accumulated have little effect on the looks or function of the pond. The MPS proposal of dredging has derailed the important funding, planning and collaboration that is needed to save the dam that creates Mirror Pond. Without a strong determined effort to replace the failing timber-crib section of the Bend Hydro Dam, it is likely that Mirror Pond will resort back to a natural river along with the decommissioning of the Bend Hydro Project.

The Bend Hydro Dam is governed by the authority of the Oregon Water Resources Department. The OWRD is now reviewing the hazard rating to consider the increased housing and recreation that has occurred below the dam in the last decade. This review could change the hazard rating from significant to high to address the probable loss of life in the event of a dam failure. The hazard rating is the basis of all dam safety and a high rating will increase inspection and safety standards, including the creation of an emergency action plan.

There could also be addition analysis of the structural stability of the dam due to the increased occurrences of needle bay failures and the use of sheet-pile to control these failures as stated in the recommendations of the 2015 OWRD inspection. These single skin sheet-pile repairs disregard the recommendations of Gannett Fleming Engineering who performed a condition assessment of the dam in 2014 for the Bend Metro Parks and Recreation District. This report stated that dam failure could happen at anytime and recommended that the timber-crib section be replaced with a new concrete dam.

At this time, HB 2085 dam safety bill, is working its way though the Oregon legislature on its way to becoming law. This law will give the OWRD the authority to obtain an injunction to lower the water level behind dams that are a threat to lives and property. This could leave Mirror Pond without water and expose the dreaded mudflats.

Its time for the City of Bend to realize that PacifiCorp is acting in the best interest of their stockholders to rid themselves of this deadbeat dam that has no financial prospects, and understand that the community's emotional attachment to the pond is being used as a bargaining chip.
