Average precipitation for the region encompassing the Lamine River basin is 38.5 inches (Waite et al. 1988). The greatest amount of precipitation falls in May and June (MDNR 1986). Average annual runoff for the region is 10 inches.
USGS Gaging Stations
Currently there is one U.S. Geological Survey (USGS) gaging stations operating in the Lamine River Basin. A stage recorder is located on the Lamine River at State Highway A bridge near Otterville and its period of record is from 1987 to the present. Subsequent to a major fish kill in 1989, a crest station was installed on Muddy Creek at the Highway H bridge north of Georgetown.
While most of the permanent flow in the Lamine River Basin is represented by the mainstem Lamine River, Flat Creek, Richland Creek, Muddy Creek and Heath's Creek, there are 64 third order or larger streams in the basin. Many of these streams have permanently flowing reaches during years of normal precipitation. Due to the complexity of the watershed, stream intermittency is best illustrated by USGS 7.5 minute topographic maps. A listing of 7.5 minute quad maps covering the mainstem and longest reach of each stream of fourth or larger order is provided (Table Hy01) to expedite access to information about flow as well as other stream characteristics.
No major dam or hydropower projects exist in the Lamine River basin at this time. Approximately 20 lakes over two acres in surface area exist in the basin (MDNR 1984). Spring Fork Lake, a water supply reservoir for Sedalia, has a surface area of 178 acres and is the largest lake in the basin. Manito Lake, 77 acres, is the only other large lake in the basin. Manito Lake is located 4.5 miles south of Tipton at the Manito Lake Conservation Area and was built for recreation.
