  • The Salt River at the Clarence Cannon Dam, the Monroe City Lake and old Bowling Green Lake are three of 56 new additions to the state of Missouri’s biennial draft list of impaired waters.
    According to the draft list, which includes 387 listings on 227 separate waters throughout the state, the Salt River has been added because of the amount of oxygen dissolved at the dam in Ralls County. The Monroe City Lake has been identified because mercury was found in fish tissue at the late. The old Bowling Green Lake has been included because of the level of chlorophyll-a found in the water.
    This is not the first time the old Bowling Green Lake has made the list. In 2012, the lake was identified because of its phosphorus and nitrogen totals.
    The Salt River in Pike/Ralls counties has made the list before, too. In 2012, a section of the river in Ralls County was noted when mercury was found in fish tissue. In 2008, the amount of oxygen dissolved at Mark Twain Lake’s re-regulation dam earned the river a spot on the list.
    Black Creek and Hunnewell Lake in Shelby County are on the list, dating back to 2012. Black Creek was included because of the amount of oxygen dissolved and its escherichia coli level. The source of the escherichia coli was listed as Shelbyville’s wastewater treatment facility.
    As for Hunnewell Lake, it was added because mercury was found in the tissue of fish caught in the lake.
    Escherichia coli is also the reason that a section of the South Fabius River in Knox/Marion counties is on the list. The source could not be identified.
    Mark Twain Lake was added to the list in 2002 when mercury was identified in the tissue of fish.
     
    Impaired waters list
     
    According to the Missouri Department of Natural Resources (DNR), the list helps state and federal agencies keep track of impaired waters not addressed by normal water pollution control programs.
    Under Section 303(d) of the federal Clean Water Act each state is required to identify waters not meeting water quality standards and for which adequate water pollution controls have not been required.
    A copy of the proposed 2014 303(d) list can be seen at www.dnr.mo.gov/env/wpp/waterquality/303d.htm.
    The DNR will host public availability sessions on this issue from 10 a.m. to 3 p.m. on Nov. 13 and Dec. 11 at the Lewis and Clark State Office Building, 1101 Riverside Drive, in Jefferson City. Department representatives will be available at these sessions to answer questions.
    A public hearing is scheduled at 9 a.m. on Jan. 22 at the same location. The DNR will accept written comments through Jan. 31. Comments should be sent to the Department of Natural Resources, Water Protection Program, P.O. Box 176, Jefferson City, MO 65102-0176. E-mail comments may be sent to trish.rielly@dnr.mo.gov. E-mails should include the contact information of the sender, including name, mailing address and phone number.
