Download the high-resolution A3 JPG Stephenson County Map ZIP directly from this page. Stephenson County in northern Illinois is centered on Freeport, with Lena and Pearl City to the west, Orangeville to the north, and Dakota in the northeast. U.S. 20 provides the clearest east-west road reference, while Routes 26 and 73 organize much of the north-south travel shown on the map. Beneath that simple road pattern, the Pecatonica River and a dense network of creeks cut low valleys between noticeably higher northern hills.
The WebP maps embedded in the article are sized for quick browser viewing, while the matching original JPG files make small creek names and road numbers easier to enlarge or print. A practical way to explore the county is to find Freeport first, move west to Lena and Pearl City, north to Orangeville, and northeast to Dakota. Then trace the Pecatonica River, Richland Creek, and Cedar Creek before switching to the elevation layer to see how those valleys sit below the surrounding uplands.

Freeport and U.S. 20 provide the clearest road reference
Freeport is the strongest landmark on the general county map. The built-up area sits slightly south of the county center, U.S. 20 crosses east to west, and Route 26 runs north-south through the city. Cedarville is close to the north, and Orangeville lies farther north along the same general corridor. To the west, Lena and Pearl City sit near Route 73 at different latitudes, making the western half easy to organize around a second north-south road.
Dakota is the clearest northeastern community and lies near the Route 75 corridor. Davis is farther east near the county boundary, while Ridott and German Valley provide references toward the southeast. The county’s northern edge meets Wisconsin, so the nearby names outside the boundary are useful for understanding where Stephenson County ends rather than treating the road network as if it continued inside the same county.
The Lena–Pearl City side of the county is much less densely settled than Freeport. Community labels are farther apart and small roads and streams occupy more of the map. Lena sits close to Route 73 and an east-west road, while Pearl City lies farther south on the same broad corridor. This contrast between the Freeport area and the western countryside is one of the first patterns visible on the general map.
East of Freeport, U.S. 20 continues toward Ridott and the Winnebago County side, while the road network toward Dakota and Davis forms a separate northeastern set of connections. Highland Community College is also marked just west of Freeport and provides another local reference near the main city. The general map is therefore best for county shape, road numbers, and the full set of labeled communities before moving to the more specialized water and elevation views.
The six-city index shows Freeport’s size and a wide northern spread
The city-index map removes most local-road detail and highlights six communities. The supplied ranking places Freeport first with 23,505, Lena second with 2,761, Orangeville third with 1,045, Pearl City fourth with 745, Cedarville fifth with 690, and Dakota sixth with 645. These figures are treated only as values printed on the supplied city index; they are not presented here as newly verified current population counts.
The relative positions tell the more useful story. Freeport sits well south of the other northern and western communities. Lena and Pearl City occupy the west side, Orangeville lies near the north-central part of the county, Cedarville is close to Freeport on the north, and Dakota is far to the northeast. Rather than forming one linear chain, the six places spread across several directions around Freeport.
The simplified city view does not include every place in the county. Davis, Ridott, German Valley, and other smaller labels are easier to find on the full county map. The index is useful for a narrower question: where are the six highlighted communities relative to one another, and how strongly does Freeport stand apart as the main urban center? Once that layout is familiar, the water map is easier to interpret because the creeks and river valleys can be related back to recognizable towns.
Pecatonica River, Richland Creek, and Cedar Creek shape the central drainage
The terrain-and-water map is organized around the Pecatonica River. It crosses the central county in a winding corridor and is closely associated with the lower terrain around Freeport. Richland Creek descends from the north into the central drainage, while Cedar Creek approaches from the northeast. Finding those three waterways first makes the many smaller tributaries and branching valleys much easier to follow.
Rock Run is one of the strongest labels on the eastern side, and Yellow Creek crosses the southern interior. East Plum River appears near the southwestern edge, while Green Creek and several smaller tributaries occupy the southeast. Lake Le-Aqua-Na stands out in the northwest, with Willow Lake near the Freeport side of the county and Millers Pond farther east. The standing-water features are much smaller than the river system, but they provide useful local landmarks.
Lake Le-Aqua-Na is especially useful for orienting the Lena side of the county. Illinois DNR identifies Lake Le-Aqua-Na State Recreation Area in Stephenson County north of Lena, and the supplied map places the lake in that same northwestern section. It is visually distinct from the long, branching Pecatonica River system and helps separate the western recreation area from the central river valley.
The water layer is intended for general geographic reference rather than flood-hazard, water-quality, navigation, parcel, or legal-boundary decisions. A mapped creek or lake shows relative location, not public access, navigability, or a current regulatory condition. More specific water-use, fishing, flood, or legal questions require the appropriate current official source.
A 203 to 351 meter range separates river valleys from northern uplands
The supplied elevation layer reports an actual range of about 203 to 351 meters and a mean near 265 meters. The lowest dark-green corridors follow the Pecatonica River and several major tributaries through the central and southeastern parts of the county. In contrast, tan and brown terrain spreads across much of the north, northwest, and northeast, with the strongest high colors concentrated close to the northern boundary.
The northern high ground is deeply dissected rather than flat. Richland Creek, Cedar Creek, and many smaller streams carve long green valleys into the higher hills, while similar branching channels divide the Lena–Orangeville side of the county. Comparing the water and elevation maps makes the relationship clear: the blue stream lines repeatedly occupy the same lower corridors that appear green on the terrain surface.
The southern half is generally lower than the highest northern terrain, but it is not perfectly flat. Yellow Creek, East Plum River, and many smaller tributaries create shallow valleys between gentle hills. Around Freeport, the Pecatonica River lowland and nearby elevated surfaces occur close together, so the city area also contains more topographic variation than the road map alone suggests.
The elevation surface is designed for county-scale comparison, not parcel surveying or engineering design. The 203–351 m range is useful for recognizing the Pecatonica River valley and the higher northern ridges, but it does not provide survey-grade elevation for a specific property. Construction, drainage, flood, and legal decisions require more precise and current data.
Which Stephenson County map should you use first?
For towns and roads, start with Freeport and U.S. 20, then use Route 26 to locate Orangeville and Route 73 for Lena and Pearl City. The city index is faster when the main question is simply where the six highlighted communities sit relative to one another. For water, begin with the Pecatonica River, Richland Creek, and Cedar Creek, then add Rock Run, Yellow Creek, and Lake Le-Aqua-Na. The elevation layer becomes most useful after those waterways are familiar because it shows which valleys are low and where the higher northern hills rise around them.
The ZIP below contains four high-resolution JPG files matching the county-and-road map, city-index map, terrain-and-water map, and elevation map on this page. Each image is 3638 × 2572 pixels in landscape orientation, making small road and stream labels easier to enlarge or print than in the browser-sized WebP versions. These maps are general reference products, so current traffic, legal parcel boundaries, flood determinations, water rules, and survey-grade elevations should be checked against the appropriate official source.
Frequently Asked Questions
What is the easiest community to use as an orientation point in Stephenson County?
Freeport is the clearest starting point. U.S. 20 and Route 26 pass close to the city, while Lena and Pearl City lie west, Orangeville north, and Dakota northeast. The city index also makes Freeport the most prominent of the six highlighted communities.
Which map best shows Pecatonica River and the major creeks?
The terrain-and-water map is the clearest choice. It shows Pecatonica River, Richland Creek, Cedar Creek, Rock Run, Yellow Creek, and Lake Le-Aqua-Na in one county view. It is intended for general geography rather than flood, navigation, or legal-water-boundary decisions.
Where are the higher and lower areas on the Stephenson County elevation map?
The supplied elevation layer shows the Pecatonica River and major tributary valleys as lower green corridors. Higher terrain spreads across much of the north, northwest, and northeast. The actual range is about 203 to 351 meters with a mean near 265 meters.
