Glossary
Reservoir
A reservoir is a water body created or enlarged by a dam to store runoff for flood control, hydropower, water supply, or recreation. On Lake Insights, reservoirs are the managed lakes whose levels follow rule curves—not free-flowing natural lakes.

Why it matters
Storage pools rise and fall on operator schedules, not only on rainfall. That shapes ramp access, timber exposure, current in the tailrace, and whether today's bass are on main-lake structure or far up a warming creek arm.
Technical context
Engineers distinguish active storage, flood storage, and dead storage below intakes. Recreation "full" is an operating target, not necessarily maximum physically possible storage.
