The Upper North Platte River watershed headwaters is located in north-central Colorado, close to Walden, CO. The Sierra Madre mountain range is on the west side of the headwaters and the Snowy Range mountain range is on the east side. Snowmelt from both of these mountain ranges together contribute approximately 75 percent of the water flow in the North Platte River. The fires’ effect on water supplies in the coming years will depend on the amount of snow fall and snowpack received in the watershed during the winter and early spring. There may be slightly higher incidences of sediment runoff in isolated areas where there is little or no ground cover due to the fire.
