Thoreson Drain Number 64

Thoreson Drain Number 64 was constructed in 2016-17.

Length: 1.88 miles

This drain outlets into the north branch of the Goose River at a point of about 1,950 feet south of the NE corner of the SW 1/4 of Section 5 of 147-52. This drain was constructed along the west side of the SW 1/4 of Section 5 of 147-52, the west side of Section 8 of 147-52, and the east side of Section 18 of 147-52 for approximately 1,930 feet to the north branch of the Goose River.

The watershed area of this drain is about 3.2 square miles. Soils are predominately Glyndon silt loam, also some Bearden silty clay loam, and Fargo silty clay loam. Using the North Dakota SCS Hydrology Manual the soil complex number for the watershed is 70. The watershed is approximately 97% cropland with the remainder of roads and farmsteads.

This drain has a bottom width of 8 feet with side slopes of 5:1 roadside and 4:1 field side. The channel grade will be 0.07% for the north half-mile and 0.05% for the remainder of the channel. All existing culverts will be removed and replaced with new corrugated metal culverts except the 54-inch by 110-foot CMP between the SW corner of Section 8 and the NE corner of Section 18. The existing 54-inch by 110-foot CMP between Sections 8 and 18 was installed by the Traill County Highway Department in the spring of 2015 and was installed to adequate size and grade.

The channel design uses the 10-year frequency run-off curve from the North Dakota SCS Hydrology Manual to determine the required capacity. The channel is designed to remove 0.044 inches of run-off per hour from a watershed of 2,050 acres. This design will remove the run-off (1.01 inches) from a 24-hour, 10-year frequency rainfall (3.5 inches) in 22.8 hours. The run-off produced from this storm event for this watershed is about 171 acre-feet under antecedent moisture condition II. All hydraulic data for the channel and corrugated metal pipe will be contained on data sheets for this drain.

The past 15 years' crop losses due to flooding have been very severe in this area.

This drain should have minimal impact on any identified wetlands. Identified wetlands are not to be drained by this drain.

Viking-Lindaas Drain Number 44

Viking-Lindaas Number 44 was constructed in 1966.

Length: 2.25 miles

This relatively short drain has worked quite well. It has been cleaned out several times. The outlet was stabilized (paid for by FEMA) in 2006 and cleaned again in 2011. Some culverts are in need of resetting or replacing.
