NOTICE - Bozo Pond (7/25/2018)
Due to the growth of blue-green algae in Bozo Pond it is advised that swimming in the pond is to be avoided at this time. Ingesting of pond water may result in sickness to humans and pets.
Blue-green algae are very common in late summer in Iowa ponds, especially those with plentiful nutrients. This is not a critical situation. The big lake appears to have very good water quality with little to no nuisance algae species. There is no problem with fishing in Bozo Pond and the fish can be eaten after being washed thoroughly and cooked properly.
When it comes to enjoying our lake and ponds, safety continues to be the number one priority. When in doubt, stay out.
More detailed summary of investigation of Bozo Pond on July 24,2018
Tim Snyder was here yesterday, July 24, 2018 to treat the big lake and investigate Bozo. I had talked to Tim yesterday after I noticed blue-green algae in the pond, especially the northeast corner. Blue -green( cyanobacteria) "blooms" can be a problem for three reasons: 1) they tend to be on the surface and reduce the sunlight penetration to the more beneficial green algae that are deeper in the water column which results in less photosynthetic oxygen production deeper in the pond, 2) Blue-greens are short-lived and after they die decomposers ( other bacteria and fungi) breakdown the blue-greens and consume DO (dissolved oxygen) resulting in low oxygen levels for fish, 3) the blue-greens sometimes release toxins as they die and the toxins can make humans sick if ingested and can kill other aquatic life.
Tim and his colleague tested Bozo for DO, dissolved oxygen, at various depths. They found DO concentrations of 16 ppm(parts per million) at 1 ft, 13ppm at 2 ft, 8 ppm at depths of 3 to 6 feet, and less than 2 ppm at depths greater than 6 feet. Most warm water fish need at least 6 to 7 ppm to survive. This data indicated the algae (both green and blue-green) are producing lots of oxygen near the surface, but not very deep. Tim said that treating the pond may cause more decomposition and reduce the DO to levels that are dangerous for fish. For that reason and because the dying blue-greens may give off more toxins he advised not to treat Bozo.
Tim and I talked about ways to ensure better water quality in Bozo. He recommended treatment early in the season, like we do on the big lake, as the surest way to not have problems later in the summer. He also said that installing the correct type of aeration system for the pond would help. He emphasized the need to put the proper system in.
The good news is that our situation is not critical and that Bozo and Andy's ponds are doing what they are designed to do, that is , be a buffer for the big lake. Tim said that big lake is in very good shape, especially for an Iowa lake in late July. The water clarity is down from early in the summer, which is normal, but there is an abundant amount of highly beneficial green algae that produce DO and start the food chains.
After discussing with Tim, I think that we should put a sign up telling people to avoid swimming in or ingesting water from Bozo pond and that pets should not drink the pond water. A notice should be posted on the Holiday Lake website as well as mass emailed and notice given to each house with water front to Bozo.

Announcement - 7/6/2018
The Holiday Lake Fish Committee is pleased to report that the June 30th lunch fundraiser was very successful!
Over $1900.00 was raised for the fish fund, which is a large portion of our anticipated fall stocking.
The efforts of Jeff and Cami Milner along with Mike Ehrig and his crew of volunteers was the heart of our success with this fund raiser. Thanks to you all very much!
Of course, none of our efforts, without the support of the Holiday Lake Community, would have led to our success. Once again, Holiday Lake members have shown fantastic community spirit.
The Holiday Lake Fish Committee cannot thank you enough for such great support!
Fish Committee Update - 6/18/2018
With summer nearly upon us, we on the Holiday Lake Fish Committee would like to welcome back our
returning seasonal members as well as our newer residents. We would like to take this opportunity to
inform everyone what we've accomplished recently and our future plans.
First, one of our long-time members, Mike Ehrig has recently left our group. We would like to
thank him for all his time and effort over the years and wish him the best of luck.
Recently concluded our spring stocking with the following:
- 1500 Bluegill @ 6" - 7"
- 1000 Crappie @ 4" - 5"
- 2600 Red ears @ 5" - 6"
- 1500 Catfish @ 8" - 10"
- and a special deal of 750 Crappies in 8" - 10"" range.
Note: We are stocking larger fish in an effort to reduce mortality rates.
Our plans for the fall stocking are tentatively as follows:
- 1000 Walleye
- 1000 Yellow Perch
- 500 Smallmouth Bass
The fish committee has also begun an ambitious program to place permanent (man-made) structures
around the entire lake. These porcupine-looking structures will be placed in at least 17' - 18' of
water and will not interfere with boating/recreational activities nor pose any safety risks. We
will periodically keep you posted of our progress.
In conjunction with the Holiday Lake Board of Directors, committee members will engage in ongoing
monitoring/researching water conditions, aerator feasibility study, plant life, and fish populations
to ensure Holiday Lake waters remain a healthy environment to sustain quality fishing.
Lastly, we are in the preliminary planning stage for our annual Poker Run. We are currently seeking
out people who would like to be one of the 5 stops. If you would like to do this, please contact us at
your earliest convenience.
If anybody has any questions, concerns, suggestions, please feel free to call us up.
Have a GREAT Summer!
