The role of tributary streams in sedimentation of Lions Lake, Warrensburg, Missouri
MetadataShow full item record
Sedimentation of aquatic ecosystems is a natural process which can be detrimental in manmade lakes and restored wetlands. It caused a problematic decrease in water depth in Lions Lake resulting in increased hydrophyte growth and a negative impact on fish populations. Five water overflow and stormwater drainage channels carry sediment into the lake. Planned restoration includes dredging the lake and constructing wetlands to trap sediment, but concerns about the sources of the majority of the sediment prompted further investigation. I examined the amount of sediment contributed by water channels from January 2010 - October 2010 by collecting water samples during rain events and dry periods and filtering out the suspended sediment. Three drainage channels on the east side of the lake carried significantly more sediment than the other two channels. Results can be used to identify the most effective placement of mitigation structures in order to minimize continued sedimentation.
