2015  Flowering Rush Treatment Areas  8/3/15 - 2nd Treatment

Good news!!!!   This year PRWD is starting the transition to operational/management treatments.  The plots that have less than 5% flowering rush biomass will not be treated in 2015. Plots that have 6% to 20% flowering rush biomass will receive one treatment at the beginning of August.  Plots with greater than 20% flowering rush biomass will receive two treatments - early July and early August.  We are still conducting research.  Each plot is sampled for biomass three times - early June, mid July, and late August.  By sampling the biomass, we will be able to document treatment effectiveness and longevity.  This information  will be used to guide us in determining how often treatments will be required to maintain a low flowering rush population.

Mechanical Harvest of Curly-leaf Pondweed to begin in June

Notice is hereby given the Pelican River Watershed District is conducting an aquatic invasive species control project involving mechanical harvesting of Curly-leaf pondweed infestations on Big Detroit Lake.  Mechanical harvesting is restricted to areas infested with Curly-leaf pondweed and conducted between mid-June and mid-July.  Treatment maps will be posted on this web site once they have been received from the MN DNR.

Signatures for lake-wide control of aquatic invasive species are not required for the pelican River Watershed District Curly-leave pondweed control project as the MN DNR has waived the signature requirement as allowed by state statute.  The law requires notification to lakeshore owners on how to opt out of treatments.  According to Minnesota Statutes (103G.615, Sec. 78, Subd 3a,b,c), the District is required to notify landowners of proposed treatments, offering them an opportunity to request that mechanical harvesting not occur on waters adjacent to their property.  (Adjacency is defined as waters within 150 feet of the shore lake-ward between property lines.  It is the landowner's right to to request mechanical harvesting not be done in front of their property, however it should be noted this project aims to reduce Curly-leaf pondweed aquatic invasive species populations which interfere with navigation, impair recreational activities, and cause harm to native plant populations.  Landowner's may exercise this right by immediately notifying the District in writing of their wish to "opt-out" of proposed mechanical harvesting areas for 2015  prior to the start of such action.  Contact Tera Guetter, Administrator, Pelican River Watershed District at 218-846-0436 or Tera.

Flowering Rush Treatment to Begin in June

Notice is hereby given the Pelican River Watershed District is conducting an aquatic invasive species research project involving sampling and herbicide  treatments of Flowering Rush on lakes Big and Little Detroit, Curfman, Sallie and Melissa.  Two types of herbicide research treatment plans will take place:  1.  Diquat used to treat submersed/mostly submersed Flowering rush in mid-June followed by a second treatment in late-July to early-August; and 2. Imazapyr used to treat emergent Flowering rush in less than 2 feet of water depth in mid-June on Curfman Lake.  It is recommended that irrigation using lake water in treated areas cease for five days after treatment.  The research includes assessing the response of Flowering rush to treatments.  Treatment maps will be posted on this website once we receive permits from the MN DNR.

Aquatic Weed Pick Up

Pelican River Watershed District will begin the aquatic weed pick up program following Memorial Day week-end.  Please remember that this is for aquatic vegetation only.  We will not pick up garbage, garden waste, branches and leaves.  DO NOT place your aquatic vegetation on the road.  DO place it on the edge of your lawn or your driveway.

2014 Flowering Rush Report

Mississippi State's Geosystems Research Institute has released the report for the 2014 Flowering Rush study.  The study was a collaborative effort between the Dr. Gray Turnage, Dr. John Madsen, and the Pelican River Watershed District staff. The report is available to download.

Shoreline Planting of Hwy 10 Overlook Complete

Most of the shoreline planting on the Hwy 10 Overlook was completed the week of May 25 under the direction of Marsha Watland of Becker SWCD.  Assisting her were staff from Conservation Corps, City of Detroit Lakes, and Becker Soil and Water.  

On Friday, June 5, another 300 native plants were put in by Becker Soil and Water and Pelican River Watershed staff.

 

Ice Push Damage Repair - Permits are Required

This winter's cold temperatures and lack of snow cover has caused some serious shoreline damage from lake-ice pressures.  While planning your recovery from winter remember that permits are required from the District for any work within the Shore Impact Zone.  This includes repairs from this year's ice-push damage.

Water Management Plan Update

The Pelican River Watershed District Board of Managers is seeking your input to help us with updating the District’s Water Management Plan. The District is involved with environmental education, water quality (monitoring, storm water, shoreline restoration), aquatic invasive species management, etc. All work that watershed districts do during the plan period is controlled by the updated plan. Minnesota Watershed Districts are required to update their Water Management Plan every 10 years.
