I was wondering what a catfisher does when the algae bloom hits Utah Lake. I found this on the not-so-dark web:
Utah Lake, Jordan River, Canals Algal Bloom Monitoring 2018
Update May 15, 2018
On April 21, 2018, satellite imagery interpolation suggested cyanobacteria cell counts above the recommended recreational health thresholds. The suspected bloom didn’t appear to be lake-wide and was most pronounced in the northern portion of the lake from Saratoga Springs to Lindon Marina.
Sampling
Division of Water Quality (DWQ) scientists collected samples at five locations on May 3, 2018:
Saratoga Springs Marina
American Fork Marina
Lindon Marina
Jordan River outlet
State Park Harbor
The monitoring crew reported that the water looked moderately clean at the sample collection sites. While satellite imagery and buoy network data showed a spike in cyanobacteria activity earlier in the week, both showed this activity was low when samples were taken.
Test Results
All five samples were shipped to Phycotech for cell counts and genera/species identification and tested in-house for cyanotoxins. Toxin test strips were non-detect for microcystin at all five locations but anatoxin-a results were suspect. Therefore, all five samples were sent to the Utah Department of Agriculture (UDAF) lab for further anatoxin-a analysis.
On May 8, the UDAF Lab confirmed that anatoxin-a was not detected for all samples and PhycoTech reported no detections of cyanobacteria cells.
It appears that a localized cyanobacteria population grew and disappeared quickly. This kind of activity is not surprising since it’s early in the season and cyanobacteria in the lake haven’t established a baseline population yet. DWQ plans to conduct weekly routine HAB monitoring on Utah Lake beginning May 14, 2018.
Sooo, could somebody translate that?
When does the bloom shut down fishing in UL? Where do you go after that? And when does it clear again?
