English: Aerial view of Martis Creek Lake and Dam in Nevada and Placer Counties, California, USA. The dam is located in Nevada County, approximately 5.5 miles (9 km) east of Truckee. The lake, when full, extends south along Martis Creek into Placer County. The lake lies next to the Truckee-Tahoe Airport, whose runway can be seen at far right in the picture. This photograph appears to have been taken in the summer when the water level was quite low. California State Route 267, also known as North Shore Road, runs across the picture in the distance at the base of the hills. View is to the south.
