SR 121 - Blooms Ditch - Remove Fish Barriers - Complete September 2016

This project removed three culverts under State Route 121 and installed two large box culverts that are 26-feet wide and 16-feet wide respectively to improve fish passage in Blooms Ditch.


How you benefit

Protects environment
Replaces outdated culverts that are a barrier for fish with culverts that are built wider than the existing stream channel. They are also sloped like a natural stream. The wider culverts are intended to simulate what is found in a natural stream bed.
