the structure shows minor disrepair of the various steel and timber gates, handrails, and
timber walkways, and shows deterioration of the concrete piers of the canal regulator.

Previous attempts to protect the invert of the flume (e.g. coating with epoxy
paints) have yielded only marginal results, with the most common rehabilitation to dote
being installation of quarter-inch thick steel liner plates over selected portions of the
pipe invert. Within the past several years, approximately 75% of the bottom third of the
pipe has been relined in this manner. This appears to be the most suitable solution to the
problem, as it is estimated that the quarter-inch steel plates will provide approximately
15 years of service before requiring replacement, at a reasonable cost and with minimal
maintenance. Rehabilitation of the flume (excluding the wasteway) would then involve
the following work:
I. Installing quorter-inch steel plate over the remaining 25% of the bottom third
of the flume;
2. Repairing the deteriorated concrete;
3. Reconditioning the steel check gates in the regulator;
4. Reconditioning the timber overflow gates;
5. Replacing the timber stop logs in the emergency spillway at the flume outlet
with a steel gate;
6. Repairing or replacing defective handrailing;
7. Replacing unsafe portions of the timber walkways.

The wasteway structure shows some deterioration of the concrete in the floor, and
the timber gates are leaking and reportedly difficult to operate. The difficult operation
of the gates can be partially attributed to the existing hoists, and these hoists should be
replaced with threaded stems and crank-type operators to provide easier and more
reliable gate operation. Power operators for these gates could be installed in conjunction
with the yate hoist replacement. Recommended rehabilitation of this structure consists
of the following items:
I. Repairing the deter iorated concrete;
2. Reconditioning of the timber slide gates;
3. Replacing the existing hoists and stems with motor-driven hoists and threaded
stems.
The total estimated cost to rehabilitate the Horse Creek flume (including the
wasteway) is $77,800, and is summarized in Table B-4.
