They provide easy access for the gate operator but can present maintenance difficulties. The gate is susceptible to blockage and can be dislodged from the guides. If maintenance is required, the reservoir has to be drained. The gate stem should be buried in riprap or encase in concrete. {{Picture |image= <!-- Add image file name (ex. image.jpg) --> File:slidegate.jpg |link= <!--Add link..."

A few questions to ask yourself: #Do I need to make regular releases? If so, a gate that is easy to access and operate is needed. If not, and your dam is not very high, a siphon may meet your needs. #Is my dam remote and difficult to access? If so, a low-maintenance system may be best. #Is ice damage a concern? If so, caution with use of inclined slide gates a..."
- 17:3117:31, 24 June 2022 diff hist +562 N Abandonment Created page with "Abandonment is another alternative to replacing or rehabilitating a conduit. Abandonment is typically used when a pipe is too deteriorated to rehabilitate and the improvements to the dam do not require replacing the conduit. Abandoning a pipe can cost significantly less than removing a pipe and does not require disturbing the embankment of a dam. A common practice for abandoning pipes is to use a cellular concrete grout to fill the existing conduit and any voids surround..."
