Background & Purpose
A pristine old growth habitat State park with many visitors, Munson Creek houses one of the largest Ponderosa Pines in Oregon and the creek is a major salmon spawning stream with high juvenile rearing potential. However, five of Munson Creek's culverts were failing in 2006 causing heavy pooling, road failure, and added difficulty for spring spawners to access Musnon Creek's upper reaches. Two culverts were replaced with bridges, two were replaced by 12 foot culverts and one was removed and the road decommissioned.
Project purpose: to compare and contrast conditions of Munson Creek before and after failed culvert replacement to determine ecological success.
