Yellow Flag Iris
Contractor selected is Dale Dressel, Owner, Northern Aquatic Services. Dale has treated yellow iris on Lake Minnesuing for 3 years. He reports a 90% reduction in yellow iris growth during that time. Growth continues in boggy, hard to reach areas adjacent to shore. They have tried cut stem and foliar applications of glyphosate, and both work equally well. Fees: $300/trip fee, $100/hour (chemicals included). Although he hasn’t seen a map, he said he can cover a lot of ground in one day and doesn’t expect it to take longer. Steve has worked with Dale before, so coordination of maps and permissions should work well.
Our interns will inventory yellow iris locations and flag them for treatment. They will also request permission to treat from owners identified in previous years. Dale prefers that the intern who worked on ID’ing and mapping yellow iris locations and contacting owners be in the boat with him when he treats. This will make it easier for him to locate plants and know where permission ISN’T granted.
Cheryl talked with Mark Sundeen (WDNR) about the permit. They do not need specific locations of iris and suggested we send in the permit for 1 acre. The landowner permission forms can serve as notification. USFS lands can be included on the LOA permit for yellow iris control. The USFS would just be considered a landowner, and as long as we have their permission, we will be good to go. Permit application will be submitted before the end of June. Mapping and landowner permissions can follow. Permit fee will be $45.
Aquatic Invasive Species Surveys
Early season plant survey underway (looking for curly leaf pondweed )– no AIS found so far Comprehensive point intercept aquatic plant survey to be completed later in the summer (Steve and one intern)
Water Quality Study
Data collection is underway in May and early June and will continue until lake turnover (late October – early November). Steve trained our interns, Zach Clemens and Nile Merton, to collect samples including: Within 24 hours of ice out (when lake is mixed).
Weekly testing: dissolved oxygen, temperature, light penetration, and specific conductance at each meter from surface to bottom, at 5 locations around the lake.
Weekly: outlet flow
Every 2 weeks: nutrients, chlorophyll from surface to just below thermocline Every 2 weeks (alternate to above): zooplankton
Additional tasks completed:
Flow meter installed at the outlet
Rain gauge logger on a WDNR‐owned island
