Blue-green algae wait-before-swimming lake sign

Ready-to-use prompt

Create a blue-green algae wait-before-swimming sign for lakeside campsites, community ponds, triathlon training groups, school water days, and vacation homes. Make it look like a folding shore warning sign, phone-advisory screenshot area, green paint-like water sketch, rinse-station arrow, and small map to a shaded picnic alternative. Include check local swimming and fishing advisories first, stay out if water looks like paint, foam, scum, mats, discoloration, or smells bad, keep children and pets away from shoreline algae, rinse with tap water after suspected contact, contact a professional or local hotline if symptoms appear, and report photos to site managers. Do not teach toxin testing, show graphic illness imagery, or replace local closure notices or medical advice.
