A new vision for Mirror Pond-but no quick fixes


       Like any problem that has existed for many decades fixing Bend’s cherished Mirror Pond on the Deschutes River as it flows through the city will not be accomplished quickly.
            But after several recent years of debate and public input the group charged with developing alternatives has unveiled what it believes could be a creative solution to accommodate various  interests.
            In an early November report the group proposed a plan that would remove the Newport Avenue hydroelectric dam that has caused sediment buildup threatening to turn the pond into a marsh.
            The river would then return to a more natural flow but additional work along banks would also help retain much of the pond’s current features.  
            The pond begin to build up and deposit sediment with construction a century ago of the Newport Avenue dam, now considered in poor condition and generating little electricity for PacificCorp. It was last dredged in 1984 before current regulations now making that a considerably more expensive solution.
      Perhaps the potentially most controversial aspect of the plan would be for the city to sell two parking lots bordering Drake Park and adjacent  Mirror Pond just west of the downtown core, and use the funds to update storm water systems and build a parking structure. Then the city would encourage formation of an urban renewal district that would attract private development of mixed use retail, office and residential facilities. 
Mirror Pond full Spring of 2013
An excerpt from the Mirror Pond and Downtown Redevelopment report citing responses to public surveys notes:
            “While respondent first choice interests were divided between keeping the pond and returning the river to a natural-like path, there was a second choice scenario that satisfied most respondents. It maintained the pond while improving wildlife habitat and providing fish passage.”
The new vision is the work of the Mirror Pond Steering Committee, Management Board and Ad Hoc Steering Committee bringing together local government, business and at large citizen members.
       Earlier options presented by the group have included scenarios of no-action at this time to combinations of dredging and dam removal. Cost estimates in the earlier options ranged from $4.2 to $5.3 million to remove the dam to $3.5 to $6.4 million for dredging depending on the methods used. The new vision paper does not include estimated costs. 
       As the current discussion of what to do with Mirror Pond gained momentum, local developer Bill Smith and heavy equipment contractor Todd Taylor purchased options to buy the land underlying the water from descendants of a pioneer family. The businessmen have said they prefer a solution that would retain features of the current pond.
       The new  plan would involve:
November 2013 after drawdown to inspect dam
  • PacificCorp relinquishing ownership of the dam and moving the existing power substation to another location.
  • PacificCorp gifting the dam to a public entity, such as the City of Bend or Bend Park & Recreation District,
  • The city overseeing conversion of the dam into an area with a series of pools and riffles. This in turn, the report says, would cause the river to rise and preserve Mirror Pond at its near-historic levels.
      The result of the instream work would create fish passage now blocked by the dam while banks along the river would be reshaped to reduce sediment and improve habitat.
     With the dam and substation gone the report envisions the city selling the present Pacific Park near the site north of Newport Avenue and using the proceeds to create a new park where the substation now sits. This would also improve access along the current Deschutes River Trail. 
       Including Drake Park, the city parks and recreation district owns approximately 60% of land ajacent to Mirror Pond to the south  from Newport  to Galveston Avenue.
