Trumbull County occupies Ohio’s northeastern corner of the Mahoning Valley, with Warren near the center of its main urban area and Niles, Girard, Cortland, Hubbard, and Newton Falls forming separate reference points around it. Mosquito Creek Reservoir stretches through the north-central county, while the southern edge contains the Mahoning River and a denser pattern of cities and highways. This page separates settlement and road geography, city distribution, water features, and elevation, and high-resolution JPG originals of all four supplied maps are available in the download ZIP.
Warren is the easiest place to begin. Cortland lies north, Niles and Girard are south, Hubbard is southeast, and Newton Falls sits far to the southwest. Routes 11, 82, 46, and 193 organize the Warren and eastern side, while Routes 5 and 422 help define the west and southwest. The elevation map adds a major physical contrast that is easy to miss on the road view: western Trumbull County is broadly lower, while the eastern half rises into a much higher ridge belt.

Warren anchors the road network between the southern cities and rural north
The general county map places Warren slightly south of center, with the largest concentration of developed land and connecting roads. Routes 5 and 422 approach from the west, Route 46 links the Warren area with Cortland to the north, and Route 82 continues east through the Howland Center side. Route 11 provides a strong north-south reference on the eastern side of the urban corridor and continues toward Girard and the Youngstown area. Trumbull County’s official website identifies Warren as the county seat.
Niles lies immediately south of Warren, followed by Girard and McDonald farther southeast. Hubbard forms a separate southeastern center near the Route 80 corridor. This southern band is much more urbanized than the northern half because it connects directly with the broader Youngstown–Mahoning Valley road and settlement pattern.
Cortland lies north of Warren near the southern end of Mosquito Creek Reservoir. Routes 46 and 88 provide useful orientation there. West Farmington occupies the northwest near Routes 88 and 534, while Routes 87 and 45 appear farther north. The northeastern interior has fewer large developed areas, leaving a more open pattern of farms, streams, and local roads.
Newton Falls provides the southwestern reference near the Routes 5 and 422 corridor, and Lordstown occupies a broad developed area between Newton Falls and Warren. Champion Heights sits northwest of Warren, while Howland Center lies to the east. Trumbull County’s official community information lists Warren, Girard, Niles, Newton Falls, Cortland, Hubbard, and many smaller communities, matching the multi-center pattern visible on the map.
Six highlighted cities show a strong southern concentration
The city-distribution view highlights Warren, Niles, Girard, Hubbard, Cortland, and Newton Falls. Warren is the central-southern anchor. Niles and Girard lie farther south, Hubbard extends the pattern to the southeast, Cortland is clearly separated to the north, and Newton Falls sits at the southwestern edge. With secondary road labels removed, the concentration of major settlements in the southern half becomes obvious.
The CITY INDEX prints values beside the six city names, but those figures belong to the supplied map and are not reused here as current official population estimates. Census reference years and municipal boundaries can change. The more durable information is geographic: Warren anchors the center, Niles and Girard the south, Hubbard the southeast, Cortland the north, and Newton Falls the southwest.
Returning to the general map adds the transportation relationships. Warren, Niles, and Girard form a nearly continuous southern urban sequence, while Cortland sits north along the Route 46–88 area. Hubbard lies near Routes 7 and 80, and Newton Falls is tied to the western Route 5–422 corridor. The city map is intended for relative placement rather than driving distance; actual travel mileage depends on the road network and exact starting point.
Mosquito Creek Reservoir divides the center while the Mahoning River crosses the south
Mosquito Creek Reservoir is the most prominent waterbody on the supplied water map. It stretches north-south through the center of the northern county, with Mosquito Creek continuing from its southern end toward the Warren side. The City of Cortland describes Mosquito Lake State Park as lying in Bazetta and Mecca townships in central Trumbull County, which closely matches the reservoir’s position on the map.
The Mahoning River dominates the southern drainage. It curves from the Newton Falls side toward the Warren–Niles–Girard area, creating a low corridor through the most urbanized part of the county. West Branch Mahoning River approaches from the southwest, and Meander Reservoir lies just beyond the southern county boundary. Upper Girard Lake and Lower Girard Lake provide smaller references north of Girard.
Northwestern Trumbull County contains the Grand River and Mud Run, while the eastern side is organized by Yankee Creek and Little Yankee Run. Shenango River Reservoir appears just beyond the northeastern side toward Pennsylvania. The county therefore spans several drainage directions: Mosquito Creek through the center, the Mahoning system in the south, Grand River waters in the northwest, and eastern streams approaching Pennsylvania.
Ohio’s administrative code lists Mosquito as a state park in Trumbull County, and Cortland’s official page presents Mosquito Lake as one of the area’s major outdoor resources. The supplied water layer is still a geographic reference rather than a flood-hazard map, legal shoreline record, current depth or flow chart, or navigation product.
Elevation from about 241 to 389 meters separates the low west from the high east
The elevation legend reports an actual county range of about 241 to 389 meters, with a mean near 296 meters. The western and central-western side is dominated by green lowlands, while the eastern half shifts into yellow, orange, and brown. The highest terrain is concentrated in broad north-south ridges near the eastern and northeastern county edge.
The west is low but not completely flat. Grand River and Mud Run cut shallow valleys through the northwest, and the Mahoning River creates a stronger low corridor around Newton Falls and the southwestern side. Warren and the area west of Mosquito Creek Reservoir sit on relatively broad green and light-green terrain compared with the east.
The eastern half rises quickly. Long brown ridges occupy the central-east and continue northward toward the county line, with some of the highest colors concentrated in the northeast. The southeast also contains substantial uplands, but Yankee Creek and Little Yankee Run carve narrow green valleys through those ridges. The water and elevation maps work especially well together here because each stream follows a visible low corridor.
Brown represents the high end of Trumbull County’s locally scaled legend, not mountain terrain comparable with major mountain ranges. The elevation image is useful for county-scale comparison but not site engineering. Exact parcel elevations, road grades, drainage design, and construction measurements should come from original USGS elevation data or a professional survey.
Use Warren to compare the reservoir corridor with the eastern ridge belt
Keeping Warren fixed while switching views is the quickest way to connect the county’s geography. The road map shows Routes 82, 46, and 5 around the central city, the city view places Niles, Girard, and Cortland around it, the water map shows Mosquito Creek approaching from the north and the Mahoning River crossing the south, and the elevation layer shows terrain rising steadily toward the east.
Cortland is the best reference for the north-central reservoir corridor. Routes 46 and 88 locate the community, and Mosquito Creek Reservoir begins immediately to the north. The surrounding area contains much more open land and water than the Warren–Niles urban belt, a contrast also emphasized by Cortland’s official description of Mosquito Lake State Park.
Hubbard and Yankee Lake provide an eastern comparison. Routes 7, 80, and 193 help locate the area, while Yankee Creek and Little Yankee Run occupy long valleys nearby. On the elevation map, those valleys are bordered by high brown ridges, producing a landscape that is markedly different from the broad low ground around Warren and Newton Falls.
Choose the Trumbull County map that fits the question
Use the general county map when you need Warren, Niles, Girard, Cortland, Hubbard, Route 11, Route 82, Route 46, and the other main roads on one page. The city-distribution map is cleaner when the goal is comparing the six highlighted communities. Choose the water map for Mosquito Creek Reservoir, the Mahoning River, Grand River, Yankee Creek, and the smaller lakes and reservoirs.
The elevation map is the clearest choice for comparing the broad western lowlands with the high eastern and northeastern ridge belt. The WebP previews on the page are convenient for quick viewing, while the high-resolution JPG originals in the ZIP below are better for printing and zooming into small labels. These maps are regional reference products and should not replace legal parcel records, live navigation, flood determinations, or survey-grade elevation data.
Frequently Asked Questions
How are Warren and Cortland positioned on the map?
Warren sits slightly south of the county center, while Cortland is north of it near the southern end of Mosquito Creek Reservoir. Route 46 provides a useful road reference between the two areas.
Are Mosquito Creek Reservoir and the Mahoning River part of the same mapped corridor?
They occupy different parts of the county. Mosquito Creek Reservoir runs north-south through the central-northern area, while the Mahoning River crosses the southern part near Newton Falls, Warren, Niles, and Girard. The water map is the easiest way to compare their positions.
Can the 241–389 meter elevation range be used for surveying?
No. The elevation map is intended for county-scale comparison of western lowlands and eastern ridges. Exact parcel heights, road grades, drainage design, and construction measurements should come from original USGS data or a professional survey.
