TASD has been awarded funding from the Great Lakes Sediment and Nutrient Reduction Program to improve water quality of Lake Erie through ditch modification. TASD will be installing a two-stage ditch and riparian buffer strip along Wiregrass Ditch in the Lower Maumee Watershed in 2022.
TASD is a division of the State of Ohio tasked with mosquito control in Lucas County. Mosquito larvae thrive in still water such as abandoned swimming pools, storm sewers, standing floodwater, and unmanaged ditches. Since the 1940s, TASD has been reducing mosquito larval habitat in ditches via water management projects. With GLSNRP’s support, TASD endeavors to improve its water management program to not only reduce mosquitoes, but to reduce sediment and nutrient loads to our Great Lakes.
This event will present project plans, the importance of riparian buffers and two-stage ditches, and provide a platform for discussion between the community and project partners.
Water Management & Source Reduction for Mosquitoes
The Toledo Area Sanitary District practices, promotes, and firmly believes in utilizing integrated mosquito management (IMM) techniques for our operations. Utilizing IMM philosophies means that we approach the task of mosquito control from a holistic perspective: seeking to prevent and control mosquito populations at every possible level of their development. One branch of IMM is Water Management and Source Reduction to prevent standing water needed for mosquito larvae to survive. Large-scale reduction includes creating and maintaining ditches to ensure optimal water flow and has additional benefits for environmental health.
At TASD, we promote two-stages compared to traditional ditches for their ability to amplify efforts and benefits with the use of a secondary level and native riparian plants. Learn about how our ditch service options could be beneficial to you.
Additional Environmental Benefits
- Prevents nutrient excess from reaching waterways and creating harmful algae blooms
- The use of native-riparian plants supports pollinators and creates wildlife habitats
- Helps natural waterways retain normal turbidity
- Functions of two-stage ditches improves over time with vegetation growth
