Here is the fifth set of UD Citizen Monitoring Reports, covering the period of July 21 to Aug 6, 2010. As it is now Aug 13, the data is more stale than usual, but we will catch up with a fresh report at the end of next week.
- It was very hot and dry during the period, with a few weak spotty thunderstorms.
- Dissolved Oxygen conditions were poor and widespread. Severely low DO (< 2 ppm) was observed in several dead-end canals and in a few upper tributaries.
- Major accumulations of Nuisance Aquatic Vegetation were observed at Diamond Pond, particularly near the spillway. Minor accumulations were observed elsewhere.
- Total Enterococcus bacteria were elevated in many locations including a few streams and ponds in the Broadkill watershed, several tributaries and canals in the Inland Bays and Broadkill watersheds, and at one bay-side site in Fenwick Island.
- Harmful algae blooms were varied and widespread. Prymnesium and Karlodinium have been blooming at the Prime Hook boat ramp. Chattonella and Fibrocapsa have been blooming in some canals and tributaries, and some non-toxic diatoms and dinoflagellates have been blooming in Love Creek. In the ocean, Karenia papilionacea, the relatively less toxic, or non-toxic relative of Karenia brevis (a.k.a. FL Red Tide), was detected at very low cell densities, as was Pseudonitzchia spp..
