The Lake Edward Conservation Club May 2017 Newsletter.

The Lake Edward Conservation Club annual meeting will be held at the Lake Edward Town Hall from 10:00 a.m. to noon on Saturday, June 24th. The meeting is open to all. Anyone with agenda items contact Herb Nelson 651-239-4860. Our treasurer will be on site for those of you still waiting to renew your 2017 membership to the LECC. The Lake Edward Town Hall is located on County Road 3, and County Road 13.

Above average precipitation continues, so lake levels are about 7-9 inches above the long-term average elevation.In 2016, the County opened their Ditch 13 at the beach line by removing sand and plants as wide and deep as their DNR permit allows.

April 6, 2017 was out Ice Out date this year.

Treating Curly Leaf Pondweed Spring 2017 – Donations Requested

Lake Edward Conservation Club (LECC) Intends to Treat Curly Leaf Pondweed Spring 2017
Your Donations Are Needed to Fund the Project

The Problem: Curly leaf pondweed (CLP), an invasive species, has been spreading in parts of Lake Edward since at least 2004, according to the DNR. The enclosed map shows CLP is spreading, particularly in the southwest and north bays, but CLP is located in a number of places in the lake. Lake-bottom conditions vary throughout the lake, so some areas are better for thicker CLP growth. The survey for CLP needs to be more thorough using better equipment. If ignored, CLP can continue to spread and might begin to interfere with boating, swimming and fishing. Thicker CLP plant growth has been washing up more on our beaches, particularly the past few years. More CLP can also feed more dense algae growth, decreasing water clarity.

Chemically Treat CLP: Experts at the University of MN Aquatic Invasive Species Research Center and others say the best way to control CLP is with a non-toxic chemical application in the spring, when the water temperature is between 50 and 60 F, so only CLP is growing actively. It will cost less to treat smaller areas of CLP now rather than wait to treat larger areas later. So LECC intends to try chemical treatment of 15 acres of CLP in the two bays in spring 2017. We’ve been told to expect this treatment will be needed for at least the next three springs. Experts say we can also plan for future additional series of spring treatments, if and when unpredictable natural and climatic conditions cause a reappearance of thicker CLP. A lot of sun through the ice and just after ice-out is ideal for thicker CLP growth to overtake native plants.

How to Pay for It: Our primary hurdle is how to pay for the chemical treatments over three years, and likely more years in the future. One spring treatment for 15 acres is estimated to cost at least $5,000 depending on how much of the treated area exceeds 5 feet deep. Much of the area to be treated may be closer to 10 feet deep, increasing the cost estimate. The lion’s share of future treatment costs must come from donations from property owners. Please encourage your guests and neighbors to consider helping. Any amount helps. LECC’s normal funding comes from $20 members’ dues that typically total $1,400 to $1,800 annually. Your annual dues are not enough to fund the CLP treatment and dues are also needed for newsletters and other important expenses. We have already received landowner donations for CLP treatment, but we could use at least $6,000 by April 2017. Any remaining donations would be used in 2018. We appreciate a one-time grant of $1,000 from Thirty Lakes Watershed District. Each year that we treat, we’ll also apply to the MN DNR for a similar grant amount. Also, the DNR permit is free because we are treating CLP, an invasive species. That saves hundreds of dollars.
Lake Improvement District (LID)? Not Yet! – We want to try requesting your donations at first to see if that is sustainable enough so we don’t need a LID. If treatment shows enough results, but donations don’t cover the cost, we may need to consider working with County staff and Commissioners to form a Lake Improvement District (LID) that would be funded from property taxes of lakeshore property owners.

LECC Curly Leaf Pondweed (CLP) Monitoring Project

Lake Edward Conservation Club (LECC) – November 2014 

2014 Curly Leaf Pondweed (CLP) Monitoring Project

 

Long-Term Project Objective:  To monitor year-to-year changes in CLP growth in Lake Edward. CLP is an aquatic invasive species (AIS) at nuisance levels in other Brainerd area lakes where it is expensive to treat.  To help prevent similar large treatment costs for LECC, we’d like to catch CLP growth in small nuisance areas, before it might potentially become a widespread nuisance in Lake Edward. The LECC Board conducted the project in 2014 in response to specific recommendations of AW Research, the DNR, ciBioBase and Dick Osgood at a CLP conference in Brainerd in April 2012. CLP is an exotic species that the DNR identified in Lake Edward during their lake plant surveys in 2004 and 2005. The experiences of experts at the 2012 CLP conference is that some natural event, or series of events, might cause our current low population of CLP to grow to a much larger nuisance level.  If that happens, it would likely be a permanent situation. We should monitor CLP growth year-to-year with vigilance.  Heavy CLP growth in other lakes has been known to release a lot of phosphorus just at the time that algae begins to grow. In that way, CLP can also substantially reduce water clarity.

 

Conclusions & Recommendations:  CLP should be monitored every year from ice out to mid-June with visual and rake surveys. Snorkeling surveys may also be needed.  CLP should be removed by hand wherever feasible, particularly in the SW corner.  If CLP growth reaches nuisance levels, the LECC Board should consider developing a chemical treatment plan with DNR assistance. In years of very dense growth, the LECC Board should consider additional plant mapping to help direct other efforts.  CLP and native plant growth was delayed and appeared reduced in 2014. So CLP and native plant information from 2014 should provide useful baseline conditions for comparison to future years of likely greater CLP and native plant growth.

 

Project Technology:  ciBioBase has software that converts sonar log records to maps of plant growth density, lake-bottom hardness (composition) and depth.  LECC volunteers recorded sonar logs of the entire lake bottom several times using Lowrance depth finders with SD-type memory chips.

 

Budget:  The LECC Board approved expenditure of up to $3,120 of club funding in 2014.

ci BioBase annual software subscription                 $1,850

Lowrance Elite 7 HDI depth finder                            $670

GIS map to help guide volunteers where to log         $100

Fuel for volunteer’s boats                                           $500

 

Observations in 2014:

Winter/Spring:  The ice was snow covered for most of the winter, resulting in poor under-ice growing conditions for CLP.   Spring was cloudy, further limiting light availability for CLP and native plants. June was unusually wet, setting records in much of MN.  For the first time since July2011, there are no drought conditions anywhere in MN.

 

May:  We tested the sonar logging process at the end of May.  The resulting map showed sparse new growth, but dense areas of previous year’s growth particularly along shorelines.  We used a rake head on a rope to look for CLP particularly in the NW bay where the DNR found CLP in 2004 & 2005.  We found no CLP with the rake head and observed no new plants in the water column.  Water clarity was reduced beginning in May.

 

Mid-June: The plant map showed more dense growth out to about 15 feet deep.  We saw plants in the water column that the DNR identified as clasping-leaf and white stem pondweeds which are native species. I counted 72 visible plants on line 5 and 104 plants on line 4.  Dan Swanson from the MDNR accompanied LECC to look for CLP on June 20, a calm sunny day.  We used a rake head on a rope and found no CLP in the NW bay, Jolly Rogers harbor and the bar just north of Cozy Bay Resort.  We found some CLP near the Cozy Bay boat ramp. Water clarity was reduced all summer.

 

June 21:  We made a Power Point presentation about the project to members at the annual meeting.

 

July:  Just after July 4th, we snorkeled off Cozy Bay Resort’s dock to hand pull over 100 CLP plants. Each of these plants likely rooted from a turion from growth in a previous year. We also counted 65 turions on new plant tips plus a dozen or so turions that came up attached to plant roots.  A turion is a wintering bud that becomes detached and remains dormant at the bottom of the water until conditions become right to start a new CLP plant. Turions are known to remain viable for 7 or more years.

 

Mid-August:  Surface water temperature was 74 F during the sonar logging process.  The resulting map shows plant growth is denser than it was in June, but still largely medium density except for areas along the shoreline in the SW bay. We searched for visible CLP plants and with the rake head in the NW bay, the large bar in the SW and off the Cozy Bay Resort dock. There were more visible pondweed plants than in June, but no CLP plants were found except by the Cozy Bay dock. The bottom composition map shows more areas of harder bottom than the June and May maps.
