This was the flow out of the culvert at Hubbard Co. 12, about ½ mile south of the Hubbard Co. 83 turnoff. This is upstream of the Little Shingobee Inlet (LSI) flume. Other than during snowmelt, water flows through this culvert only following heavy thunderstorms or prolonged rainfall. |
|
On the left we see that the Little Shingobee Inlet flume is totally submerged - even the wingwalls are not visible. Normally this stream is nearly dry. |
|
This stream is about 25 meter wide, just above where it empties into Little Shingobee Lake. |
|
The stage in this photo is 0.9 foot above the top of the flume. The flume and wingwalls below the outlet to Little Shingobee Lake are totally submerged; all that can be seen are the datalogger shelter and the stage-recorder shelter.Typically, all the flow passes through the 2-foot-wide flume.On the afternoon of April 7, 2001, the channel was about 30 meters wide. |
|
The flume on the mainstem Shingobee River also was overtopped, although some of the wingwall boards still restrecited some of the flow (maximum stage was 0.4 foot above the tope of the flume). |
|
We see that only about 25 cm of clearance existed in the culvert that allows the river to pass beneath Hubbard County 83, just upstream of where it empties into Shingobee Lake. |
