The stop gates depicted in this section are the most commonly utilized designs. They feature rugged aluminum construction, complemented by durable and flexible ultra-high molecular weight polyethylene (UHMW) seat/seals. A resilient bottom seal guarantees a secure closure with minimal leakage. Stop gates are also available in stainless steel if the design requires a more durable, but heavier material.

Stop logs have been utilized for many years to contain water in ponds, tanks, or channels. They are used in applications where their installation or removal is required infrequently. Historically, stop logs were crafted from squared timbers, as their name suggests. However, obtaining wood in the required sizes, quality, and quantity for traditional stop logs has become increasingly challenging. The dimensional instability in wood also complicates providing timber stop logs with predictable leakage characteristics.
