Travel Directions

Traveling to Jameson Lake is straight-forward and does not require any special consideration. The main routes follow Interstates, state highways and paved county roads all the way to the site.

Use the Jameson Lake Turnoff access which is located on Hwy 2 between Orondo/Waterville and Coulee City.

If you are using I-90 Westbound, use Exit 151 at George for Hwy 283 to Ephrata; this transitions to Hwy 28 and leads into Ephrata.
If you are using I-90 Eastbound, use Exit 179 at Moses Lake for Hwy 17 to Ephrata; Hwy 17 will split east of Ephrata, stay left onto Hwy 282 which heads into Ephrata. Turn right at the intersection of Hwy 28 and Hwy 282 in Ephrata.

From northbound Hwy 28 in Ephrata, turn left at 1st Avenue NW; this will become Sagebrush Flats Road. Stay on this road - it changes names several times to become Moses Coulee Road - until it intersects with Hwy 2 and turn right onto Hwy 2; the Jameson Lake Cutoff is approximately 1/4 mile further on the left and posted.

Please note that there is a posted "DIP" not long after you turn onto Jameson Lake Road from Hwy 2 - THEY ARE SERIOUS ABOUT IT!

Follow Jameson Lake Road past Jack's Resort, approximately 6 miles, and take the first paved cutoff on the right to enter the site. We will have this posted so be looking for the signs.
