THE WATERSHED-LODI SPRING CREEK

Spring Creek located on border of Columbia

County/Dane County

Flows northwest through Lodi Marsh to City of

Lodi and then to Lake Wisconsin (303d)

Class II brown trout stream

Impacts from NPS (sediment/nutrient/loading)

SETTINGTHE STAGE FOR ADAPTIVE

MANAGEMENT DISCUSSION

NR 102 Water Quality Standards/Targets

Streams .075 mg/L

Rivers .10mg/L Reservoirs/lakes .005 to .007mg/L

Lodi Spring Creek at .08-.076mg/L so limit

would be .075mg/L

Currently at .8mg/l

WISCONSINS NEWPHOSPHORUS RULE

Water Quality Based Limits

Why?

Water quality suffering under

historic ruleschanges

deemed necessary

Maintain or restore aquatic

environment, recreational

uses, tourism

Prevention of algal blooms,

toxic algae, algal mats, odor,

low dissolved oxygen


6/22

New water-quality based limits for point sources are

often more than ten-times lower than historic limits

To achieve limits at treatment facilities, costlyupgrades would be needed.

NR217 contains provisions for compliance using

watershed-based approaches instead of upgrades Adaptive Management

Water Quality Trading

NEW WPDES PERMIT CHALLENGES FOR

CITYOF LODI

WHATWOULD UPGRADECOST

MSA completed preliminary review 2012

Estimated about 4.2 million plant upgrade

Estimated Adaptive Management costs $2.7

million not including outside funding

WHAT WE FOUND VIAINVENTORY

69 livestock operations in total

42 livestock operations have runoff issues (1500 to

2480 lbs P)

55 operations not aware of having a NMP 590 plan

(Meeting T?) 60 operations did not have manure storage\

Lots of opportunity for conservation BMPs

NEXT STEPS FOR OUR PROJECT

Commitment by Dane and Columbia County

LWCD to begin more detailed site inventory work

in 2014

Public awareness kickoff outreach meeting July

2013 local fair/mailings/etc

Data collected will be used for large scale TRM

grant applications for 2015

Final Adaptive Management Plan developed and

submitted Fall of 2015 by MSA/City of Lodi
