Goals

What we know
•NMCWD presented vegetation and water quality data – will be
shared on website
•The watershed:lake ratio is large and includes Southdale Mall
•Lake Cornelia was dominated by invasive curly-leaf pondweed
in 2015 and 2016
•Lake Cornelia is not meeting clean water goals
(phosphorus and algae are high, clarity is low)
•The watershed is the major source of phosphorus pollution
(2010, UAA report)

Vegetation strategy for 2017
•City to apply for Invasive Aquatic Plant Management permit this winter for
North and South Basins
•City to apply for MN DNR grant to manage invasive aquatic plants
•City to coordinate and fund targeted CLP treatment in early spring (about
April) per DNR rules/permit for N and S basins
•City to coordinate and fund lake study of vegetation before and after
treatment to measure effectiveness
•City to coordinate and fund algae treatments in N and S basins per DNR
permit
•City to resolve service provider issue for 2017 – feedback welcomed

What we’ve learned
•The Lake and Pond Management Policy is limited to addressing
vegetation requests, which is only part of the problem
•The policy will be under revision in 2017 - feedback is welcomed
•We don’t have a policy/plan for prioritizing and implementing clean
water improvements
•NMCWD monitoring program and City algae treatments are not
coordinated

What’s next?
•City to conduct targeted CLP treatment in 2017
•The City’s 10-year Comprehensive Water Resource
Management Plan (CWRMP) is being updated. The Lake and
Pond Management Policy is a component of that plan.
•Feedback welcomed
•Clean water improvements will be incorporated into the
CWRMP update – how to prioritize, plan, fund?
•Feedback welcomed
•Summary to City Council on Lake Cornelia in December
