Lake County occupies a striking landscape in northwestern Montana, combining the southern part of Flathead Lake with the long Mission Valley and a steep mountain wall along the eastern side. Polson sits at the south end of Flathead Lake, while U.S. 93 continues south through Pablo, Ronan, Kicking Horse, St. Ignatius, Ravalli, and Arlee. The terrain-and-water map adds Flathead River, Mission Creek, Jocko River, Swan River, and several reservoirs, and the elevation map shows how sharply the central valley differs from the eastern mountains. High-resolution JPG versions of the maps are available together in the download ZIP below.
Lake County’s official About Us page identifies Polson as the county seat and highlights Flathead Lake, Mission Valley, and the Mission Mountain Range among the county’s defining geographic features. The supplied maps reflect that same pattern. The main settlements follow the lower valley and highway corridor, while the eastern side rises abruptly into higher terrain cut by narrow river valleys.

U.S. 93 links Polson with the Mission Valley communities
On the general county map, Polson sits at the southern end of Flathead Lake. U.S. 93 heads south from Polson through Pablo, Ronan, Kicking Horse, St. Ignatius, Ravalli, and Arlee, making it the clearest north-south road reference in the county. Route 35 follows the eastern side of Flathead Lake, while Route 28 reaches west toward Big Arm and Rollins.
Finley Point, Big Arm, Lindisfarne, and Rollins provide additional references around the lake. Farther east, Swan Lake sits within a separate mountain corridor served by Route 83. Route 209 appears near the northern edge, while Route 212 helps locate Charlo and the western part of the Mission Valley.
Route 200 meets the U.S. 93 corridor near the southern part of the county. The static road map is useful for regional orientation, but mountain-road conditions, construction, and seasonal restrictions should be checked through current transportation information before travel.
The city map connects Polson with Ronan and St. Ignatius
The city-connections map uses Polson as its hub and links it with Ronan and St. Ignatius. The printed index lists Polson at 5,428, Ronan at 2,001, and St. Ignatius at 977. These are values embedded in the supplied map and should not be treated as guaranteed current population estimates. Current demographic figures should be checked through recent U.S. Census Bureau data.
Ronan is labeled 12 miles from Polson, and St. Ignatius is labeled 26 miles away. Both measurements are straight-line distances, not road mileage. Actual driving distances are longer because the route follows U.S. 93 and local streets rather than the direct connector lines.
The city map makes the shared valley location easy to see. Ronan lies south of Polson, while St. Ignatius is farther down the same Mission Valley corridor. Returning to the general map adds Pablo, Kicking Horse, and Charlo as intermediate local references.
Flathead Lake and Flathead River define the northern water landscape
The terrain-and-water map is dominated by Flathead Lake across the northern part of the county. Polson sits at its southern end, while Table Bay and Canal Bay appear on the western side. Lake Mary Ronan provides a smaller but useful landmark in the northwestern hills.
South of Flathead Lake, Flathead River leaves the lake area and continues through lower country. Pablo Reservoir sits farther south within the Mission Valley. The combination of lake, river, and broad lowland helps explain why the county’s main settlements and highway corridor occupy this central part of the map.
The terrain-and-water map is intended for geographic reference. It does not establish flood zones, water depth, parcel boundaries, water rights, navigation conditions, or safe crossing locations. Current boating, access, and water-condition information should be checked through the appropriate agencies.
Mission Creek, Jocko River, and reservoirs divide the southern valley
The Mission Valley contains several prominent reservoirs south of Polson. Pablo Reservoir lies in the central-northern valley, with Lower Crow Reservoir, Kicking Horse Reservoir, and Ninepipe Reservoir farther south. These water bodies provide clear reference points away from the highway corridor.
Mission Creek runs near the St. Ignatius side of the valley and gathers tributaries from the surrounding foothills. Farther south, Jocko River follows a lower corridor toward the Arlee area. Lagoon Lake appears along the eastern mountain side and helps mark the transition from valley floor to higher terrain.
In the northeast, Swan River follows a long mountain valley. Its narrow corridor contrasts sharply with the broad surface of Flathead Lake and the open Mission Valley, showing how varied Lake County’s water settings are within a relatively compact area.
Elevation rises from about 766 meters to 2,955 meters
The elevation map reports an actual Lake County range of about 766 to 2,955 meters, with a mean elevation near 1,213 meters. Flathead Lake, Polson, Ronan, St. Ignatius, and much of the central Mission Valley appear in dark and medium green, indicating lower terrain.
The highest relief is concentrated along the eastern and southeastern side. Yellow, orange, and brown ridges rise abruptly above the valley, and Swan River follows a lower route between mountain slopes. The elevation transition is especially sharp because high terrain stands immediately beside the broad central valley.
The western side contains hills and mountain terrain of its own but is generally less continuously high than the eastern wall. Arlee occupies another lower corridor in the south, with higher terrain rising again around it. The elevation map is intended for county-wide comparison only and should not be used as survey-grade or engineering-grade data for a specific property.
Polson, Mission Valley, and the eastern mountains form a simple map framework
A practical way to read Lake County is to start at Polson and Flathead Lake, then follow U.S. 93 south through Ronan, St. Ignatius, and Arlee. Route 35 and Route 28 help with the east and west sides of Flathead Lake, while Route 83 provides a separate reference in the Swan River mountain corridor.
Water features add the next layer. Flathead River and Pablo Reservoir help with the central valley, Lower Crow, Kicking Horse, and Ninepipe reservoirs distinguish the southern Mission Valley, and Mission Creek with Jocko River provide lower drainage references farther south.
The WebP images embedded in the article are convenient for quick browsing. The high-resolution JPG files in the ZIP are better for printing or enlarging small road, creek, and reservoir labels. Because these are static reference maps, current road access, water conditions, and seasonal restrictions should be checked through current official information.
Frequently Asked Questions
Are the Polson-to-Ronan and St. Ignatius distances driving distances?
No. The city map shows Ronan at 12 miles and St. Ignatius at 26 miles from Polson as straight-line distances. Actual driving distances are longer because U.S. 93 and local roads do not follow the direct connector lines.
Where is the highest terrain in Lake County?
The highest terrain is concentrated along the eastern and southeastern mountain side. The central Mission Valley around Polson, Ronan, and St. Ignatius is much lower.
Can the 766–2,955 meter elevation range be used for a property or engineering project?
No. The range is a county-wide reference for comparing the lower Mission Valley with surrounding mountain terrain. Precise site elevations should come from an authoritative source such as the USGS 3D Elevation Program and, when necessary, a professional survey.
