PROJECT INFORMATION:
The district has approached the Commission for Level III construction funds to rehabilitate four
underflow structures that were evaluated during a recently completed Level II Study. These
1930's vintage structures handle upstream return flow and flood flow and protect the canal from
flood related erosion. The four crossings are in various states of disrepair, with Madden Draw
being in the worst condition, as the underflow structure has already partially failed (caved in).
Additionally, the corrugated metal pipe utilized at these crossings is not sized correctly to handle
extreme events. Rehabilitation of these crossings would provide protection to the canal during
flood flows and ultimately improve the ability and reliability of the system to deliver water to the
users.
