  • Geneseo Town Board discusses algae on Lake GENESEO — Recent concern over blue-green algae in Conesus Lake became a topic of discussion at the special Geneseo Town Board meeting that was held at Long Point Park on Thursday. Blue-green algae is a naturally occurring part of the Conesus Lake ecosystem, though when found in high concentration, these tiny, floating organisms may pose a risk to lake residents. Cathy Higgins, inspector for the Conesus Lake Watershed, refers to these highly concentrated clouds of algae as "blooms." Blooms usually form in warm, shallow waters and have often been linked with drastic weather patterns. They tend to gather along the shoreline, particularly on the east side of Conesus, though sightings have been reported in areas all over the lake. Due to the sometimes-toxic nature of the blooms, the Conesus Lake Watershed Council strives to increase community awareness about the problem.

It will find paths through manure piles and across chemically enhanced lawns. When it reaches the lake, delivering a nutrient-saturated jolt, it will feed the growths of algae that threaten the lake's health. (February 2, 2006) Democrat and Chronicle
