MonitoringLocationDescriptionText Small spring coming out of the ground/gravel. Spring flows out of a small 'island' between Grassy Creek and the spring pool (30 ft X 10 ft). Output of spring flows both directly into Grassy Creek and into short spring branch into Grassy Creek. Water sample take in flowing water near the spring orifice. Discharge was difficult to estimate. The spring output directly into Grassy Creek and into the spring branch must be summed together. Best estimate in the spring with high flow. UTM Easting: 645680 Northing: 4123482
