Honeoye Valley Association

Secchi Disk Program

 

The HVA has launched a volunteer Citizen Secchi Disk Program to collect water quality data at six near shore areas of the lake. This additional water clarity and surface water temperature data will complement the water quality data that is being regularly collected by the Honeoye Lake Watershed Task Force at several deep water locations. This near shore water quality data will assist us in better understanding how the lake conditions can vary due to weather conditions and different locations around the lake.

 

The most recent weeks near shore water clarity and temperature data is shown below:

 The Gronwall's visual BGA Update for Monday October 1st.

 

Monday morning (10/1), Today the blue-green algae bloom that has

been occurring appears to be slowly dissipating. However, we still

could see light blue-green algae in the water column. Also, many of

our monitoring locations still had light surface scum.

 

Fall has arrived with the surface water temperature of 66.4 F. A

drop of

4.8 F over the last week.




The Gronwall's visual BGA Update for Monday September 17th.

 

Monday morning (9/17), Today the blue-green algae bloom that has been

occurring for the last several weeks appeared to be subsiding. The lake had

only very light visible algae in the water column and no surface scum at all

10 of our monitoring sites. However, a few of our sites still had very

green looking water. If we get clear sunny sky conditions with clam winds

we could see the blue-green algae move back up to the surface later this

week.

 

We have had confirmed complete water column mixing events on August 22nd

and September 10th providing nutrients to fuel this BGA bloom.

The Gronwall's visual BGA Update for Monday September 24th.

 

Monday morning (9/24), Today the blue-green algae bloom that has been

occurring for the last several weeks appeared to be more intense again. The

lake was calm at our open water site with visible light surface scum. Then

the wind came up and the rest of our monitoring sites did not have

significant surface scum. Many of our sites still had very green looking

water.

 

We had a strong wind generating whitecaps late Friday afternoon followed

by a thunderstorm. Saturday we went out and took a Temperature & DO profile

and confirmed another complete water column mixing event providing nutrients

to continue to fuel this blue-green algae bloom.



The Gronwall's visual BGA Update for Wednesday September 12th

 

Our report is delayed this week because of the rain last Monday and other

commitments we had on Tuesday.

 

Wednesday morning (9/12), Today the blue-green algae bloom that has

been occurring for the last four weeks appeared to be more intense. We had

calm winds this morning causing a light surface scum over many, but not all

areas of the lake.

 

We have had confirmed complete water column mixing events on August 22nd

and September 10th providing nutrients to fuel this BGA bloom.

Monday morning (9/3), Today the blue-green algae bloom that has been

occurring for the last three weeks appears to be abating. However, the

water column still looked very green. No algae surface scum. With 90 F

temperatures forecasted for later this week, its important for all of us to

stay vigilante.

 

DEC Region 8 Honeoye Lake Fish Kill Report

 

"A significant fish kill on Honeoye Lake was reported on July 29th. Nine

yellow perch and one largemouth bass were collected on July 30th and

submitted to Cornell College of Veterinary Medicine. The final pathology

report suggests that bacterial infection (Aeromonas sobria, Aeromonas

hydrophila, and Plesiomonas shigelloides) was the primary cause of the fish

kill. All three are common in freshwater and often cause infections in

fish. As with all fish kills, there are always more than one factor

involved. Increasing water temperatures, low dissolved oxygen in some

portions of the lake, and algae bloom conditions may have secondarily

contributed to fish mortality."

The Gronwall's visual BGA Update for Monday August 27th

 

Monday morning (8/27), Today the blue-green algae bloom that has been

occurring for the last two weeks is still very visible. Especially along

the north shore of the Lake. The rest of the lake has only very light to

light algae in the water column withy no to light surface scum.

 

We had a thermocline disturbance August 8-10 followed by a complete lake

mixing event last Wednesday August 22nd due to wind and rain storms. This

will fuel our blue-green algae bloom for a while longer.

 

We still do not have a final report from the DEC Region 8 Fisheries

Department and Cornell University on the cause of our YOY perch fish kill.

We will share this information with you just as soon as it becomes

available.

The Gronwall's visual BGA Update for Monday August 20th

 

Monday morning (8/20), There was a noticeable reduction in blue-green

algae from last Monday 8/13. However, several of our blue-green algae

monitoring sites had very green colored water indicating the presence of

blue-green algae. We did not observe any surface algae scum.

 

We have been able to confirm that we had a thermocline disturbance August

8-10. This would have mixed nutrient rich deep water with surface water

fueling the current blue-green algae bloom.

 

We still do not have a final report from the DEC Region 8 Fisheries

Department and Cornell University on the cause of our YOY perch fish kill.

We will share this information with you just as soon as it becomes

The Gronwall's visual BGA Update for Monday August 6th

 

Monday morning (8/6), Today all of our surveillance/monitoring sites had

no to light algae in the water column with no surface scum. However, last

weekend there were a few isolated locations along the NW shore that had

suspicions algae blooms.

 

We do not have a final report from the DEC Region 8 Fisheries Department

and Cornell University on the cause of last week's YOY perch fish kill. We

will share this information with you when it becomes available.

The Gronwall's visual BGA Update for Monday July 30th

 

Monday morning (7/30), We had a complete lake mixing event last Tuesday

July 24th which mixed the nutrient rich deep water with the surface water.

This caused several isolated near shore BGA blooms starting last Thursday.

Today most of our surveillance/monitoring sites had light algae in the water

column with light surface scum. A few near shore locations still had a fair

amount of surface algae scum.

 

We have experienced a lake wide YOY perch fish kill over most of the lake

starting Sunday (7/29). DEC Region 8 Fisheries collected dying perch

samples for testing by Cornell's Fish Pathology Department today. It will

take several weeks before the Cornell test results are available. We will

keep you posted.

The Gronwall's visual BGA Update for Monday July 23rd

 

Monday morning (7/23), The Gleotrichia bloom we reported last Monday

7/16 appears to have run its course. All of our surveillance/monitoring

sites had no visible algae to only very light algae in the water column with

no surface scum. Water clarity has decreased by ~2.3 feet from last Monday

7/16. Water clarity today was 5.6 feet. Surface water temperature was 76.8

The Gronwall's visual BGA Update for Monday July 16th

 

Monday morning (7/16), Many of our surveillance/monitoring sites showed

signs of a Gleotrichia bloom, but a few of our sites were almost completely

algae free. Sandy Bottom Park Swimming beach has been closed due to

concerns about this bloom. Water clarity has decreased by ~4.6 feet from

last Monday 7/9. Water clarity today was 7.9 feet. Surface water

temperature was 81.6 F.

 

This blue-green algae species gets its nutrients directly from the

shallow water bottom sediments. Shallow areas that do not have good water

circulation could collect Gleotrichia in more dense quantities.

The Gronwall's visual BGA Update for Thursday July 12th

 

Thursday afternoon (7/12), The Gleotrichia in the water column became

more dense in some small isolated near shore areas today. Today's very

calm wind and bright sunny sky brought it up to the water surface. This

blue-green algae species gets its nutrients directly from the shallow water

bottom sediment.

 

Other near shore areas had very clear almost algae free conditions.



The Gronwall's visual BGA Update for Monday July 10:

 

 Monday morning (7/10), All of our surveillance/monitoring sites showed

no signs of a BGA bloom.

Only very light to light algae in the water column. Water clarity has

increased by 3.3 feet from last

Monday 7/2. Today it was 12.5 feet. Surface water temperature decreased by

0.6 F to 78.8 F.

 

We are observing light Gleotrichia in the water column. This blue-green

algae species gets its

nutrients directly from the shallow water bottom sediments. Shallow areas

that do not have good

water circulation could collect Gleotrichia in more dense quantities.

 

Always use your own visual assessment before making contact with the lake

water at this time of

year as the blue-green algae situation can change daily if not hourly. The

DEC will report on their

assessment of our blue-green algae bloom situation for this week late Friday

afternoon on their BGA

The Gronwall's visual BGA Update for Monday June 11th:

 

Monday morning (6/11), Water clarity has declined about 3.3 feet over

the last week. Currently 7.9 feet. Most of our surveillance/monitoring

sites showed no signs of a BGA bloom. A few of our sites had very light to

light algae visible in the water column. This was a significant improvement

from last week.

 

Working with Cornell University we determined that we had a very strong

(20-25 MPH) south wind on May 30 & 31. The lake was stratified and anoxic

on May 28th. Cornell's thermistor temperature data every meter from the

surface to the bottom confirmed that we had a thermocline disturbance

(underwater waves/rocking thermocline) on May 30 & 31. We feel that this

was the source of nutrients that fueled last week BGA bloom.

The Gronwall's visual BGA Update for Monday June 4th:

 

Monday morning (6/4), water clarity was still very good at 11.2 feet.

Most of our surveillance/monitoring sites showed no signs of a blue-green

algae bloom yet. However, two sites had sparse small green algae

dots/clumps and one near shore site had a moderate amount of green

filamentous algae visible in the water column.

 

Always use your own visual assessment before making contact with the lake

water at this time of year as the blue-green algae situation can change

daily if not hourly. The DEC will report on their assessment of our

blue-green algae bloom situation for this week late Friday afternoon on

their BGA alert web page.

The Gronwall's visual BGA Update for Monday May 28th:

 

Monday morning (5/28), we saw no visible blue-green algae in the

surface water at all of our monitoring sites. The water clarity was an

exceptional 12.5 feet.

 

We have had a couple reports of blue-green algae blooms in the last few

days that were actually duck weed, a small aquatic plant, that floats on the

 

surface and sort of looks like a blue-green algae bloom.

 

We have started collecting at least 3 water samples a week for blue-green

algae testing by SUNY ESF. If any of these samples test above the NYSDEC

blue-green algae bloom criteria they will report that on Friday.

 

Always use your own visual assessment before making contact with the

lake water at this time of year as the blue-green algae situation can

change daily if not hourly.
