Premier Lakes reports algae, reduces aerator sound; planting at Lake E4-A delayed pending Edgewater agreement
Summary
Premier Lakes and district operations staff reported routine algae and higher water levels but no compliance issues in the annual lake maintenance audit; a compressor enclosure reduced sound at Masters Lake from 64 to 52 decibels, though staff said the tone remains a concern and plantings at Lake E4-A are on hold pending agreement with the Edgewater Condo Association.
Bill Kurth of Premier Lakes told the River Ridge CDD on July 23 that lakes, preserves and dry retention areas are generally in good shape but seasonal algae growth has been spotted. He said a cabinet installed around the compressor at Masters Lake reduced noise levels "from 64 to 52 decibels," placing the measurement roughly halfway between the compressor and the screen line, which he called acceptable in his view.
Operations Manager Shane Willis said the issue is not only decibel level but the tone produced by the aerator and that staff will consider relocating the compressor; Mr. Willis will coordinate with Bill and Alex Kurth and report findings at the next meeting. Mr. Willis also presented the Annual Quality Assurance Audit for lake maintenance and dry retention, reporting that water levels were high, audits will be performed earlier next year, and there are currently no compliance issues.
Separately, Mr. Schultz summarized flooding concerns in Edgewater and recommended additional piping, littorals and rip-rap for Lake E-4A. The Board reached consensus that Cana lilies should not be planted, and Mr. Kurth said plantings in Lake E4-A will be delayed until an agreement is reached with the Edgewater Condo Association; staff will resubmit a proposal when ready.
