Premier Lakes reports algae and quieter aerator; board pauses plantings at Lake E4‑A
Summary
Premier Lakes told the River Ridge CDD the lakes are generally in good condition but algae was observed; a cabinet reduced aerator noise at Masters Lake from 64 to 52 decibels but staff said the tone remains a concern and plantings at Lake E4‑A were delayed pending agreement with the Edgewater Association.
Bill Kurth of Premier Lakes reported to the River Ridge Board on July 23 that the lakes, preserves and dry retention areas are in good condition overall, though algae growth was noted. Kurth said a cabinet installed around a compressor at Masters Lake reduced the measured sound level from 64 to 52 decibels, which he described as acceptable.
Operations Manager Shane Willis cautioned that the issue is not only decibel level but the "tone" of the aerator, and the board discussed possibly relocating the compressor. Mr. Willis and Mr. Kurth will coordinate with staff (including Alex Kurth) and report findings at the next meeting.
Mr. Schultz summarized issues in the Edgewater area and recommended meeting with Edgewater management. The board reached consensus not to plant Canna lilies and agreed to delay plantings in Lake E4‑A until an agreement is reached with the Edgewater Association (through Cambridge Management); staff will resubmit a proposal when appropriate.
Kurth left the call before the meeting’s close. The board received an annual quality assurance audit for lake maintenance (presented by Mr. Willis), which reported high water levels, no compliance issues, and improvement in lake conditions under current maintenance.
The board did not take immediate remedial action beyond directing staff to coordinate further study and to report back.
