UPPER TURTLE LAKE ASSOCIATION: 2018-19 Upper Turtle Lake CLP Planning Project

Purpose

The Upper Turtle Lake Association is sponsoring a curly-leaf pondweed monitoring and planning project. Specific project activities include: 1) CBCW watercraft inspection; 2) Volunteer AIS monitoring; 3) AIS outreach & education; 4) Spring and summer whole lake point intercept plant surveys; 5) Pre-post treatment monitoring; 6) CLP bed mapping; 7) CLP turion monitoring; 8) Dye study in north bay of the lake; 9) Lake water quality monitoring. Project deliverables include GIS data & maps of areas monitored, CBCW, AIS, and water quality monitoring data in SWIMS, education materials developed, dye study report, and CLP and turion monitoring reports. Special Conditions: 1) Sponsor shall contact DNR immediately if a new AIS is found; 2) Water quality, WAV, and AIS monitoring personnel shall be trained and follow DNR approved protocols; 3) Water quality, WAV, and AIS monitoring data shall be entered in SWIMS; 4) Education materials shall be consistent with the Department\2019s statewide education strategy for preventing and controlling AIS; 5) WDNR\2019s Aquatic Plant Management in Wisconsin guidance shall be followed for point-intercept surveys and pre-post aquatic plant monitoring. This scope is intended to summarize the detailed project scope provided in the application and does not supersede those application tasks/deliverables. Data, records, reports, and education materials, including GIS-based maps and digital images, must be submitted to the Department in a format specified by the regional lake coordinator.

CLP Turion Survey data from Upper Turtle Lake
Following several years of high CLP density on the lake that resulted in severe navigation impairment for many residents, mats of rotting vegetation, and poor summer water quality (UTLA board, pers. comm), the UTLA decided to authorized follow-up plant surveys in 2017 so they could update their APMP in 2018 and revisit active management.

Pretreatment survey for Upper Turtle Lake in May 2018.
As a prerequisite to updating their plan in 2018 and to compare how the lake’s vegetation had changed since the last point-intercept surveys, the UTLA and the Wisconsin Department of Natural Resources authorized CLP density and bed mapping surveys on June 20-21, and a full point-intercept survey for all aquatic macrophytes on July 17, 2017. During the initial 2010 early-season survey, we found CLP at 52 sites (8.7% coverage with a mean rake fullness of 1.87) of which 35 had a rake fullness of 2 or 3 suggesting 5.9% of the lake had a significant infestation. In 2017, we found CLP at 216 points (36.3% coverage with a mean rake fullness of 1.97) with 140 of these having a rake fullness of 2 or 3 (23.5% of the lake had a significant infestation). This represented a 315% increase in total CLP coverage as well as a 300% increase in areas with significant CLP.
