Section 5: Goals for management of aquatic plants
Goal A: Control ______________[Invasive Aquatic Plant species] to reduce interference with use of
the lake.
[Objective A-1: Measurable outcome – Delineated acres of ______________[Invasive Aquatic
Plant species] in spring]
Goal B: Control ______________[Invasive Aquatic Plant species] to increase or protect native aquatic
plants.
[Objective B-1: Measurable outcome – The frequencies of native plants shall ______ (be
maintained or allowed to increase – or, possibly, in the case of Eurasian watermilfoil on
Minnetonka or other cases – may decrease during the year of treatment and then return to, or
exceed, pre-treatment levels in a subsequent year) according to results of P-I surveys in midsummer]
Goal C: Control ______________[Invasive Aquatic Plant species] to __________________ [address
other problems
[Objective C-1: Measurable outcome – Water clarity as indicated by Secchi depth shall not
decrease (basis for identification of a significant decrease?) ]
Section 6: Proposed actions to achieve goals and a map showing the location of the proposed
actions
A. Provide a brief description of the pest management options considered besides the use of pesticides,
keeping in mind the impact to water quality, impact to non-target organisms, feasibility, and cost
effectiveness. Also list any relevant previous Pest Management Measures.

B. Proposed actions: Selective control by application of herbicide to areas with curly-leaf pondweed
in up to ______ acres, which is ______ % of the littoral zone (water depth up to 15 feet).

Section 7: Conditions of APM permits to be issued as part of this plan, including variances
A. Variance: Application of herbicide to _____ acres, which is greater than 15% of the littoral area
and a variance from the provision in M.R. 6280.0450, Subp. 4, A.

County: ____________ Lake: _______________
Date: ____________________
Justification: A variance is justified because control of ______________[Invasive Aquatic Plant
species] in more than 15% of the littoral area has significant potential to increase or protect native
aquatic plants.
B. Waiver: Waiver of requirement for signatures (M.S. 103G.615) [details to be described in an
appendix]
Justification: Obtaining signatures would create an undue burden on the permittee because
_____________________________________________ (complete the sentence with the explanation
provided by the applicant)
C. Condition: Any application for a permit to allow subsequent chemical treatments to control native
submersed plants within the same season shall be subject to inspection and shall be permitted no
more than 50 shoreline feet, or half their lake frontage, whichever is less, by 50 feet lakeward plus a
15 foot channel to open water. Offshore treatment of native submersed plants shall not be permitted.
Should native submersed plants rebound to a large extent causing recreational nuisances, this
limitation will be revisited. Permits to allow treatment to control native submersed plants shall require
a separate permit and shall require annual signatures of approval from all landowners whose
shorelines will be treated.
Section 8: Required monitoring:
a
What?
By whom?
Delineation of curly-leaf
To be determined
pondweed or other invasive
aquatic plants in spring
b
A point-Intercept survey in mid-
To be determined
summer when native
submersed plants are at or near
maximum levels of abundance
c
Observations of Secchi depth at
biweekly intervals, i.e., twice
per month, or more frequently,
from 1 May through 30
September.
