From Cortez to McPhee Reservoir: Roads and River Valleys on a Montezuma County Map

Download the high-resolution JPG originals for this Montezuma County Map together in the ZIP below. The maps cover Colorado’s far southwestern corner around Cortez, Dolores, and Mancos, where McPhee Reservoir, the Dolores and Mancos river systems, broad uplands, and much higher eastern terrain create very different landscapes across the county. They also make it easy to compare the road network around Cortez, straight-line city connections, and an elevation range of roughly 1,403 to 4,014 meters.

Cortez is the easiest reference point for getting oriented. US 491 passes through the central part of the county near Cortez, while US 160 runs east toward Mancos and continues beyond the county. The official Montezuma County emergency plan identifies Cortez as the county seat and largest city, with Dolores and Mancos as the other incorporated municipalities. That same relationship is clear on the supplied maps.

Cortez anchors the main road network across the central county

The county map places Cortez near the center of the most visible road network. US 491 runs through the area and continues north past Lewis, while US 160 extends east toward Mancos and the La Plata County side of the region. Several numbered state and local roads branch away from these routes, giving the northern and eastern half of the county a denser road pattern than the broad areas farther south and west.

Towaoc appears southwest of Cortez, while Lewis lies to the north. Durango is labeled outside the county on the east side, which helps place Montezuma County within southwestern Colorado. The map is most useful when you need roads, place names, streams, and the county boundary together rather than a simplified city-only view.

The county map uses Cortez as the main reference point for US 160, US 491, Lewis, Towaoc, and the wider Montezuma County road network.

Road labels such as 184, 145, 27, and 28 appear in the northern and eastern part of the map, with additional numbered routes in the south and southwest. They are useful visual references, but the map is not a live road-condition product. For driving, closures, seasonal access, or construction, current information from the responsible road agency should be checked separately.

The city map shows how Cortez, Dolores, and Mancos relate to one another

The city-connections map uses Cortez as the hub and highlights Dolores and Mancos as the other major city points. The map reports straight-line distances of about 9 miles from Cortez to Dolores and about 15 miles from Cortez to Mancos. These are not driving distances, so the actual mileage on local roads will be longer and will depend on the route.

Dolores lies northeast of Cortez, while Mancos is farther east. Their placement makes the different parts of the county easier to understand before looking at the larger road map. Cortez functions as the central road reference, Dolores sits close to the Dolores River and McPhee Reservoir area, and Mancos provides a useful reference for the eastern valleys and the US 160 corridor.

Cortez is the hub on the city map, with Dolores about 9 miles away and Mancos about 15 miles away by straight-line distance.

The simplified city view does not show every community. Places such as Towaoc and Lewis are better located on the full county map. Using the two maps together avoids treating the city-connections layer as a complete settlement map and makes it easier to move from a quick city comparison to the detailed road network.

McPhee Reservoir and the Dolores–Mancos waterways divide the northern and eastern valleys

McPhee Reservoir is the most prominent body of water on the terrain-and-water map. U.S. Bureau of Reclamation information explains that McPhee Reservoir was created by McPhee Dam on the Dolores River and serves as the principal storage feature of the Dolores Project. The supplied map shows the reservoir in the northern part of Montezuma County with the Dolores River continuing nearby.

Narraguinnep Reservoir and Campbell Reservoir are also labeled in the northern half. Farther east, the West Mancos River and East Mancos River occupy separate mountain valleys, with Summit Reservoir and Bauer Lake nearby. Mc Elmo Creek crosses the western and central part of the county, while Lost Canyon Creek and other smaller tributaries fill in the drainage network between the larger named rivers.

McPhee Reservoir, the Dolores River, East and West Mancos rivers, Mc Elmo Creek, and several smaller reservoirs are shown with the surrounding terrain.

This water map is a location reference for rivers, creeks, lakes, and reservoirs. It is not a flood-hazard map and does not show water depth, water quality, legal water rights, property ownership, or navigation conditions. Those questions require current information from the appropriate agencies.

Elevation rises sharply from the western uplands to the eastern mountain country

The elevation map lists an actual county range of about 1,403 to 4,014 meters, with a mean near 2,084 meters. That is a difference of more than 2,600 meters between the lowest and highest mapped terrain. Broad green areas dominate much of the west and southwest, while yellow, orange, and brown terrain becomes much more common toward the east and northeast.

The eastern county edge is cut by tightly spaced ridges and valleys, and the north-central area also rises around the Dolores drainage. A long belt of higher, dissected terrain appears south of the central county as well. Cortez and the Mc Elmo Creek area sit in comparatively lower terrain, making the contrast with the eastern high country easy to see on a single map.

The elevation map compares Montezuma County’s lower western uplands and valleys with much higher terrain along the eastern and northeastern side.

The elevation layer is intended for county-scale comparison. It should not be used as a survey, engineering surface, building-site elevation, or precise road-design reference. For those uses, consult USGS source data or professional survey information.

Choose the map based on whether you need roads, city spacing, water, or terrain

Use the full county map for Cortez, Lewis, Towaoc, US 160, US 491, and the broader road network. Use the city map for a quick comparison of Cortez, Dolores, and Mancos and the straight-line distances from the hub. The terrain-and-water map is the clearest choice for McPhee Reservoir, the Dolores River, Mancos River branches, Mc Elmo Creek, and the smaller lakes and reservoirs. The elevation map is best for comparing the lower western country with the much higher eastern mountains.

Frequently Asked Questions

How far are Dolores and Mancos from Cortez on the city map?

The supplied city-connections map shows a straight-line distance of about 9 miles from Cortez to Dolores and about 15 miles from Cortez to Mancos. These are reference distances between city points, not driving mileage, so road travel will be longer.

Which map is best for McPhee Reservoir and the Dolores River?

The terrain-and-water map is the best choice. It shows McPhee Reservoir and the Dolores River together with Narraguinnep Reservoir, Campbell Reservoir, the Mancos River branches, Mc Elmo Creek, and other named water features across the county.

Can the 1,403–4,014 meter elevation range be used for surveying?

No. The elevation map is designed to compare broad terrain differences across Montezuma County. Surveying, construction, parcel work, and engineering require more precise source data or professional measurements.
