Saturday, April 23rd, 2016 Stream Observations

General Information

• Saturday 4/23/2015
• 1:20 pm

Weather

• Sunny, with clouds
• Temperature of 66 °F
• 2 mph Breeze coming from the North
• No precipitation
• No expectation of precipitation for the remainder of the day

Water Conditions

• Stream was clear with no noticeable turbidity
• There were small items of trash in the stream 

Stream Stage 

• The stream was at 13.5 cm mark on the rod inside of the culvert. The approximate height of the water behind the weir is 34.5 cm (1.13 ft) 
• Estimated flow rate: 6.24 cfs

Other Observations 

• The banks of the stream were wet, likely from the rain and subsequent discharge from the previous day. 
• The discharge is not as high as it was during rain events, nut is higher than it was earlier in the week. This is likely due to the rain events being recent. 
• The ducks were spotted again. The were looking for food downstream of the station. 

LEWAS Data

• Over the course of the day, the flow rate has settled and is not changing as much as it was during the previous day, where precipitation was experienced. 
• Water temperature followed similar patterns to other days without rain. During the Early morning, temperature was lower, and as the sun came out temperature rose and followed the ambient temperature of the are. 
• Turbidity rose slightly over the course of the afternoon.
