City staff says lake turnover caused sewer smell; dredging plans proceed with bond financing
Summary
Public-works staff told council the odor detected near Legacy Bridge was caused by lake turnover; staff said they are applying hydrogen peroxide and calcium nitrate and plan dredging timed for cooler weather, funded by a bond.
Public-works staff told the Midway City Council that residents' reports of a sewer-like smell near Legacy Bridge were caused by seasonal turnover in the lake and described short- and long-term remediation steps.
A staff member said the city has increased dosing of hydrogen peroxide and calcium nitrate to alter water chemistry and reduce odors, and that turnover periods associated with temperature changes typically last about a week. For longer-term work, staff said dredging remains planned but will likely be scheduled for fall when cooler weather is expected.
Staff said the city will pursue a bond to pay for dredging and related long-term work, and that the dredging will be timed to avoid warm-season turnover conditions. A councilor reported noticing the smell near Legacy Bridge and urged the city to proceed with planned improvements.
The report was informational; no formal action was recorded at the meeting regarding dredging timing or bond issuance beyond staff updates and the statement that the city intends to move forward with the long-term fixes.
