Lake maintenance report: algae spotted, compressor sound lowered but tone remains; Lake E4-A plantings delayed

Bill Kurth of Premier Lakes told the board that the lakes, preserves and dry retention areas are generally in good condition but that seasonal algae growth had been observed. He said a palm tree on the shoreline of Lake E7A was removed as noted in staff reports.

Regarding noise at Masters Lake, Kurth said a cabinet installed around the compressor reduced the measured sound level from roughly 64 decibels to about 52 decibels. "The sound level has been reduced from 64 to 52 decibels," he said, and called the reduction acceptable given the distance to the screen line. Operations Manager Shane Willis, who conducted the lake audit, cautioned that the issue is the tone of the aerator rather than the absolute decibel level and recommended further evaluation.

Staff will coordinate on whether the compressor can be moved; Mr. Willis and Mr. Kurth will report findings at the next meeting. Chair Bob Schultz summarized concerns in the Edgewater area — flooding, piping, littorals and rip‑rap — and recommended a meeting with Tim Wilkin at Edgewater 1 NUR to seek an acceptable solution. The board reached consensus that Canna lilies should not be planted and agreed to delay plantings at Lake E4‑A until an agreement with the Edgewater Association is reached and a resubmitted proposal is provided.

Separately, Mr. Willis presented the annual quality assurance audit for lake maintenance and dry retention, reporting that water levels were high, the audit will be performed earlier next year, and there were no compliance issues. Willis and Mrs. Adams answered questions about bubblers in dry retention areas and a deer sighting.

Next steps: operations staff will evaluate moving the compressor, coordinate with Premier Lakes on plantings once the Edgewater Association agreement is secured, and present findings at the next regular meeting.
