Details:	SUMMARY: Response to algae advisory Blue Lake DETAILS: I relayed to Rob, the 8/26/10 advisory for Blue Lake Park as > 100 000 Aphanizomenon cells / mL of water have been documented recently. Rob was aware of the release through Interlachen W PUD. Rob not concerned about discontinuing use of Well #4, closest to Lake and most shallow well, at this time. He referenced a recent study demonstrating very little surface water influence with their wells. Will keep well on-line and re-evaluate in a week ACTION NEEDED: James to forward any updates for Blue Lake to Rob that might impact Interlachen operational decisions. James to forward any follow up sampling for recent advisory at Fairview Lake to Rob.
