Notes: Sand Creek is the largest tributary to Coon Creek. It drains suburban residential, commercial and retail areas throughout northeastern Coon Rapids and western Blaine. The stream is about 20 feet wide and 2.5-3 feet deep at the monitoring site during baseflow. Sand Creek water levels fluctuated 2.06 feet in 2006, which is similar to 2005. The lowest water occurred during the moderate drought conditions of late summer when water levels were about 0.5 feet lower than earlier in the year. The highest water levels occurred after a 2.23-inch storm on June 16. Water levels rose 1.64 feet within the first four hours but receded to within 0.5 feet of pre-storm levels within the next four hours. It was typical for Sand Creek to rise and fall very quickly following rainfall. In 2005 water levels fluctuated 2.15 feet. Unusually, the highest water did not occur in spring, but rather during the fall in response to three rainfalls of >3 inches on 9/4, 9/21, and 10/5/2005 . The response to each of these rains was brief, with water levels rising from baseflow to a peak in four hours during two storms and 12 hours in the other. After peaking water levels immediately begin to fall, and are not sustained at high levels. The increase in water level ranged from 13 to 21 inches for the September and October 3inch-plus storms.
