Tumalo Irrigation District closes portions of the old Cascade Mining site due to sinkholes. The former Cascade Mining Pit on Tumalo Reservoir Road is currently being posted “no trespassing” in certain areas due to sinkholes, which developed due to the heavy snow melt and rain events. Multiple sinkholes developed causing a safety concern to both people and pets which prompted the emergency posting.
The District asks that people trespassing on unclosed portions of district property to please respect the signs and stay well away from any potential sinkhole activity. The District also asks people to please report any new sinkholes that may develop outside the newly posted areas. Please report any hazards to the District office at 541-382-3053.
The map below shows the closed portions.
Thank You,

Ken Rieck
District Manager
