Download the Cassia County Map as one ZIP containing high-resolution A3 JPG versions of the county overview, city, terrain-and-water, and elevation maps. The WEBP previews below let you inspect Burley, Declo, Albion, Malta, Oakley, the Snake River, Lake Cleveland, roads, streams, and mountain relief before opening the larger files for printing, classroom work, reports, or presentations.
Cassia County in south-central Idaho has a strong north-to-south contrast. Burley and Declo sit close to the Snake River plain, while Albion, Malta, and Oakley occupy interior valleys farther south. Beyond those towns, large mountain blocks and branching streams fill much of the county, so the settlement map, water map, and elevation map each reveal a different part of the same geography.

Burley is the best starting point for reading the county
The county overview makes Burley the easiest reference point. Cassia County’s official website lists the county courthouse in Burley, and the Idaho Blue Book records Burley as the county seat. On the map, Burley sits near the northern boundary close to the Snake River plain, with major roads and local transportation lines converging around it.
Declo lies east of Burley, while Albion and Malta sit farther south in the interior. Oakley is separated to the southwest in its own valley setting. Route 30 crosses the northern part of the county around Burley and Declo, Route 27 runs south toward Oakley, and Route 81 serves the Malta side of the county. The network becomes less dense as it enters the mountainous south.
The county outline widens dramatically south of the Snake River plain. The northern edge is relatively open and low, but the southern half contains complex drainage patterns and large mountain masses. Learning the boundary first helps with the later maps because features such as Cassia Creek, Lake Cleveland, and Goose Creek occupy very different parts of this broad interior.
The city map shows five separate settlement points
The city-connections map reduces the county to Burley, Oakley, Declo, Albion, and Malta. Burley is the hub city. Declo lies to the east, Albion and Malta extend into the southeastern interior, and Oakley sits to the southwest. The supplied city index also places Burley first in population among these marked places.
The distance labels are straight-line measurements rather than road-driving distances. From Burley, Declo is shown at about 8 miles, Albion at about 14 miles, Oakley at about 21 miles, and Malta at about 27 miles. Mountain terrain and road curves can make the actual trip longer, so these numbers are best used to compare relative direction and spacing.
The pattern also shows that settlement is not spread evenly across the county. Burley and Declo are tied to the lower Snake River plain, while Albion and Malta occupy interior valleys between higher land. Oakley has a separate southwestern position. The city map is therefore useful for understanding the county before adding the more detailed roads, streams, and relief shown elsewhere.
Snake River lowlands give way to creeks, reservoirs, and mountain basins
The Snake River is the strongest water feature at the northern edge of the terrain-and-water map. It runs along the low country near Burley and Declo, creating a clear geographic break between the open northern plain and the more rugged interior of Cassia County.
Farther south, Cassia Creek becomes one of the main named drainages, joined by Summit Creek and Cottonwood Creek in the central and eastern mountain country. Goose Creek and Big Cottonwood Creek are prominent in the southwest, where Lower Goose Creek Reservoir appears in a valley setting. Birch Creek and Clear Creek add more tributaries across the southern terrain.
Lake Cleveland is labeled in the central mountain area, with Marsh Creek nearby. H Canal and J Canal appear closer to the lower northern country, showing that the map includes both natural streams and human-made water channels. This is a geographic reference map for rivers, creeks, lakes, reservoirs, and canals; it is not a flood map, navigation chart, parcel map, depth chart, or legal water-right document.
Elevation rises sharply away from the Snake River plain
The elevation map makes the north-south contrast even clearer. The northern strip around Burley and Declo is shown in darker green, marking the broad lower plain. Moving south, the terrain rises into several large mountain blocks. The highest relief is concentrated across the central-southern interior, with additional high ridges in the southwest and southeast.
The supplied elevation graphic reports an actual range of about 1,260 to 3,141 meters, with a mean near 1,639 meters. Large brown areas in the central mountains are well above the green Snake River lowlands, and Lake Cleveland sits within this higher country. Long eastern ridges and the rugged southwest also stand out clearly against the lower valleys.
The colors are intended for county-scale comparison, not site-specific engineering or surveying. They are most useful for seeing where towns sit relative to mountain belts and where streams descend from high terrain into lower valleys. Exact elevation for a property, road project, or construction site requires a more precise source.
Use the maps together to connect towns, water, and relief
For general orientation, start with the county overview and city map. They show how Burley and Declo relate to the northern plain and how Albion, Malta, and Oakley are positioned farther south. If the goal is to understand the interior valleys, the terrain-and-water map adds Cassia Creek, Goose Creek, Lake Cleveland, reservoirs, and smaller tributaries.
The elevation view explains why those features appear where they do. Burley lies close to low, open ground near the Snake River, while Albion and Malta are surrounded by much higher terrain. Oakley is also connected to a separate southwestern valley system. Following one place through the different map views helps show how settlement, roads, waterways, and mountains fit together.
This approach works well for classrooms, local research, travel planning, presentations, and county-to-county comparisons. A reader can locate Burley, follow Route 30, check the Snake River on the water map, and then compare the low northern plain with the high southern mountains on the elevation map.
Frequently Asked Questions
Where is Burley on the Cassia County map?
Burley is near the northern boundary and the Snake River plain. It is the county seat and the easiest reference point for locating Declo to the east and Albion, Malta, and Oakley farther south.
Where is Lake Cleveland?
Lake Cleveland appears in the central mountain area of the terrain-and-water map. Marsh Creek and Cassia Creek are nearby, and the elevation map shows that this part of the county is much higher than the northern plain.
Which parts of Cassia County are highest?
The central-southern mountain blocks, the rugged southwest, and several southeastern ridges are the highest areas. The supplied map reports an overall elevation range of roughly 1,260 to 3,141 meters.
