Mary Park Beach may be added to state list

Two of the three products Wisconsin is required to submit to the federal government assessing the condition of its lakes and rivers are available for public comment through Feb. 20, 2012.

The products -- Wisconsin's proposed list of waters that do not meet water quality standards and a group of plans for maintaining or improving water quality in 24 of 330 watersheds across the state -- also are the subject of a Jan.5 webcast set to begin at 1:30 p.m. More information on the webcast and submitting public comments is found below.

The 1972 Clean Water Act requires states every two years to assess whether their waters meet the national goals of supporting healthy aquatic communities, habitat for wildlife and opportunities for fishing and swimming. States are to publish a statewide water quality report, develop an "Impaired Waters List" of lakes and rivers that do not meet state water quality standards, and submit plans for maintaining and improving water quality in a certain number of watersheds every cycle.

Impaired waters

Wisconsin Department of Natural Resources is proposing to remove 25 lakes, beaches and rivers from the 2012 draft impaired waters list, often referred to as the 303 (d) list, because their water quality has improved and now meets federal standards. The proposed removals, or "de-listings," reflect recent improved stream habitat and recent bacteria concentrations at those beaches, according to Aaron Larson, the DNR water resources management specialist who coordinates the impaired waters list.

At the same time, 32 waters are proposed to be added to the impaired waters list for the first time because of documentation that they exceeded numeric standards for phosphorus, mercury, bacterial contamination and recoverable zinc and copper, he says.

Among those proposed to be added to the list is the Mary Park Beach, which has suffered E.coli contamination for several summers. Other area lakes proposed to be added are in Polk County: Wapogasset Lake, Loveless Lake, Apple River Flowage, White Ash Lake, Long Trade Lake and Big Butternut Lake.

Waters where phosphorus was the problem pollutant also had to be showing signs of biological impairment such as excessive algal growth or lack of insects sensitive to pollution to be listed as impaired.

And additional pollutants are added for 19 waters already on the impaired waters list; in 18 of those cases, those waters are found to exceed standards for total phosphorus. The impaired waters list includes more than 700 lakes, rivers, impoundments or streams.

Tim Asplund, acting chief of DNR's water evaluation section, says the new listings don't mean that water quality has suddenly decreased in these waters since the 2010 impaired waters list was submitted, but likely reflect a combination of factors: new data submitted for consideration, new phosphorus standards that for the first time set numeric criteria for how much of this nutrient can be in lakes and rivers, and new methodologies for weighing whether to add or remove a water from the list, he says.

"The process of listing waters as impaired is a constantly evolving, changing process because the science and assessment methods are constantly evolving," Asplund says. "Some of these waters may have been impaired for a long time but we now have more clear parameters to make listing decisions, and in many cases, more information."
