Definition
The term “Upper Peoria Lake” is not widely recognized as a distinct geographic or hydrological entity in authoritative encyclopedic sources. It appears to be an informal or descriptive reference to the upstream portion of Peoria Lake, a reservoir on the Illinois River near the city of Peoria, Illinois, United States.
Overview
Peoria Lake itself is a 20‑mile‑long impounded section of the Illinois River, formed by a series of locks and dams managed by the U.S. Army Corps of Engineers. In colloquial usage, the lake is sometimes divided into informal segments—commonly referred to as the “upper” and “lower” parts—to describe different shoreline areas, fishing zones, or recreational sections. However, no official designation or separate entry for “Upper Peoria Lake” exists in major reference works, government publications, or academic literature.
Etymology / Origin
The name combines “Upper,” indicating the northern or upstream segment of the lake, with “Peoria Lake,” which derives its name from the nearby city of Peoria and the Peoria tribe of Native Americans. The adjective “Upper” is likely a descriptive qualifier rather than a formal toponym.
Characteristics
Because “Upper Peoria Lake” lacks an official definition, specific characteristics such as exact boundaries, surface area, depth, or ecological data are not documented separately. General attributes of the broader Peoria Lake apply, including:
- Location: Central Illinois, between the towns of Peoria and Chillicothe.
- Hydrology: Part of the Illinois River system; water levels regulated by the Peoria Lock and Dam.
- Ecology: Supports typical Midwestern freshwater species, including bass, catfish, and various waterfowl.
- Recreation: Popular for boating, fishing, and birdwatching; specific activity zones may be informally referred to as “upper” or “lower” sections by local users.
