Johns Lake 2019 Angler Survey (Creel)

Johns Lake 2019 Angler Survey (Creel)

     Johns Lake is a Fish Orlando BIG WATER BODY that is managed by FWC to keep good fish habitat. The creel is just one way they evaluate their work, along with electrofishing, guide reports, Wednesday night tournament results, hook and line samples, TrophyCatch submissions and angler diaries. FWC creels are set up the same every time they run them, so they can be compared with one another. FWC used to conduct them every five years, but they recently shortened it to every 3 years, in order to evaluate the new bass regulation implemented in July 2016 (5 bass limit of fish < 16 inches of which one may be > 16 inches).

      In 2019 the creel will run from January 6, 2019 to April 19, 2019. The creel is broken into four periods (Jan 1 – Jan 28th; Jan 29th – Feb 25th; Feb 26th – Mar 25th; Mar 26th – April
22nd). The computer randomly picks 6-week days and 4 weekend days from each period. It also randomly picks whether they will be out there in the morning, mid-day or evening. 

     The Wednesday night tournament shuts down when we “fall back” from daylight savings time and then starts again when we “spring forward” into daylight savings. There are two randomly selected creel week days that will fall during the Wednesday night tournament time. However, as mentioned above, they track the information on the Wed night tournaments aside from the creel.

     During similarly constructed creels conducted on Johns Lake in 2011 and 2016, they had largemouth bass catch rates that were around 1 bass/man-hr. For example, if two average bass fishers on Johns lake fished from 6 am – 12 pm, that would be 12 man-hrs (6 hrs fished x 2 fishers). Accordingly based on the last two creels, they would catch an average of 12 bass during their trip. 

     There are very few waters in Florida that can brag of catch rates of one bass/man-hr or higher. In the last two decades, bass catch rates this high have only been recorded in this area on West Lake Tohopekaliga, the Stick Marsh/Farm 13 Reservoir in Palm Bay, Turkey Lake (A Fish Orlando FAB FIVE) in Orlando and the Winter Park Chain (A Fish Orlando BIG WATER BODY) in Winter Park.

     One of the main reasons Johns Lake’s bass fishery is good is because the water levels fluctuate. The low’s allow for growth of terrestrial and transitional wetland plants, that when flooded, provide energy for the system via epiphytic algae (the green algae slime that is on the stems of plants). The aquatic insects and small fishes eat the algae, which are in turn are eaten by bigger predators. The highs allow for flooding and control nuisance plants (cattails, etc.), and flood associated wetlands, which after the waters subside, bring the baitfish produced in these wetlands, back into the lake to provide food and energy. While you may not believe this after the last two years of high water on your docks, the highs don’t get as high for as long as they historically used to before canals and structures were built, which is part of the reason they must spend some time treating cattails, floating mats, etc. on Johns Lake. However, it is nothing compared to the mess that would result if water levels were strictly stabilized!

     An extreme low occurred in 2001, when most of Johns Lake dried up. It stayed down until 2003, and in the process, large stemmed woody plants, etc. grew on the lake bottom. When the lake re-flooded, FWC stocked it with 250,000 fingerling bass. Stocking of bass only works on new waters and those that have dried up and re-flooded. Only a small percentage of the bass stocked survive after the first year, but these become the brood stock (spawners) that repopulate the lake. 

     With all the energy produced from the flooding of the terrestrial vegetation came amazing action for big bass in 2006 – 2012. This was documented in our 2011 creel. Approximately 400 – 600 trophy bass were caught Jan – Apr in the 2011 creel! In the first year of TrophyCatch (2012), Johns Lake was second in the state for submissions.

     All good things do come to an end, and by 2013, most of the woody stemmed vegetation produced from the 2001 drought was gone. While the catch rates for bass were still good in the 2016 creel, accordingly, with this energy source reduced, we saw a drastic reduction in memorable (> 20 inch) and trophy (> 24″) bass. 

     One trophy bass FWC shocked and tagged ($100 prize) on Johns Lake last spring was caught by an angler within one week of tagging. All the fishery biologists in the state insert $100 trophy tags in bass that they electrofish in order for the research division to get a “handle” on how many are kept and how many are released. In the past few years on Johns Lake they have tagged approximately 11 trophy bass and 9 of the 11 tags have been returned. Fortunately, the anglers released all their tagged Johns Lake trophy bass.

     FWC’s Fish Orlando annual report can be found each year on their website. You can also check out FWC’s web page. They also have a Fish Orlando app available for apple phones, but it only covers the FAB FIVE, URBAN PONDS and fish ID. It is currently being updated to IOS12. Good luck fishing!

Johns Lake Water Level Story

Johns Lake Water Level Story

     In the previous article (August 2018 Cattales), it was reported that the lake level was 99.36
NAVD88. This is incorrect due to an error in a survey benchmark used to take the reading. The correct level was 97.33 NAVD88 on September 7, 2018. Since that time, we have discovered that Orange County Survey Department takes lake elevation surveys monthly and records the official levels for all the lakes in the county. During periods of high-water, they take the readings daily. For any of you that have “stream gauges” or lake level markers you can “calibrate” your high water mark this year so far with this corrected level. JLIA is on the distribution list for these readings from now on. Sorry for any confusion.

18th Annual Johns Lake Holiday Boat Parade

18th Annual Johns Lake Holiday Boat Parade

This year is the 18th Annual Johns Lake Boat Parade! The event will be held on Sunday, December 18th at 6:15pm. Come out and decorate your boat with lights and join in the fun! Last year we had 32 boats in the parade, and many spectators at the public boat dock on Lake Winter Garden, as well on the shoreline in many backyards.

     All boats participating should gather by 6:10 PM in the NW corner of Johns Lake. THIS IS A NEW MEETING LOCATION FROM LAST YEAR. The lead boat will start the parade at 6:15 PM by blasting an air-horn several times. All boats should follow in-line and slowly head east. The parade route will follow the northern, eastern, and southern shores of Johns Lake (from Johns Lake Landing in Lake County to Twinwaters in Orange County, where the parade ends). The parade will take about 2 hours to complete. Please see the Parade Route Map.

If this is your first time decorating your boat for a parade, here are a few tips:

  • Christmas lights run on 120v AC and are designed to operate from your home electrical current. To operate lights on your boat, you will need to purchase a DC to AC power inverter. Power inverters are available at most auto parts stores, Wal-Mart, and Harbor Freight. Power inverters convert your boat’s 12v DC power to 120v AC. Inverters do have a limit as to how much power they can generate from your boat’s DC battery. Inverters are rated by watts; the more watts the inverter can handle, the more lights you can put on your boat. Most power inverters above 150 watts will need to be connected directly to your boat’s battery terminals to provide full power as 12v outlet plugs (cigarette lighters) are power limited by a fuse.
  • The use of LED lights provides the ability to power many more lights than incandescent lights. A 300-watt power inverter connected directly to your battery could power over 600 LED lights as opposed to 60 incandescent lights!  Be careful though, as some units will overheat if too much load is placed on them.  Test your lights for a period of time before the parade starts.  Make sure you use UL-approved outdoor lights as the lights on your boat may get wet and you do not want to cause a fire or shock someone on your boat!

Johns Lake Tussock Issues

Johns Lake Tussock Issues

A.K.A. – The Floating Islands

     In April 2017, FWC toured Johns Lake with Habitat and Species personnel to see if associated marshes near the turnpike could be enhanced to increase their fishery value. On May 2, sites in the northeast side of the lake were picked for a vegetation shredding project with funding available in the FWC budget. At the end of May 2018, an FWC habitat biologist out of Eustis (Steve Crawford) contracted a company to open areas that had previously been too dense for fish habitat. The contractor used “barge-like” boats driven by paddle wheels. Attached to the boats were large metal circular “cookie cutter” blades that chopped the vegetation into fine particles that could be quickly broken down by bacteria. That project is now complete.

This project activity coupled with the high-water levels and storm winds, created a situation where some of these areas of vegetation (tussocks or floating islands) had broken free and had been floating around the lake. During the week of 10/8, FWC came back out into the lake with the “cookie cutter machine,” air boats and personnel to round up and get rid of many of these nuisance tussocks. 

     Next year, they hope to open areas on the south shore of the lake that have been “choked out” with the exotic torpedo grass. However, the FWC state budget next year is challenged by several projects in the southern part of the state that will take a large portion of their funding to complete. We will update the plans as more detail is available.
