Message: An upstream gate allows for the conduit to be inspected without draining the reservoir.
This Montana Dam has a downstream slide gate but does not have an upstream gate. The reservoir needs to be completely drained in order to complete an outlet inspection.
-
-
Because this dam does not have an upstream gate, the reservoir needed to be drained to access the outlet conduit.
-
Beginning the inspection.
-
The inspection was completed using a CCTV Camera on a Pipe-Crawler. See the Investigation page for more information.
-
The inspection revealed debris in the conduit. A trashrack would help mitigate debris in the conduit.
-
Location of downstream slide gate. An additional 20 feet of HDPE is downstream of this structure.
