The TSI calculation for 2007 (which is the only year with all 

four required quarters) is 64, which meets the listing 

requirements to be placed on the verified list. This is due to 

very high chlorophyll-a values typically above 21 ug/L.

 The nutrient concentrations represent the 75th percentiles of data from the Verified Period. The target nutrient concentration used in the subsequent TMDL will be determined during the TMDL process.

* A statewide TMDL for mercury, that will address this waterbody, is scheduled to be completed in 2012.

identified as impaired under the IWR, a priority of “medium” was assigned. Exceptions are waters where the impairment poses a threat to potable water or human health, which have been assigned a “high” priority, 

and fecal coliform impairments, which have been assigned a “low” priority. All other listings as of this cycle are prioritized based on the following: it is the Department's intent that listings with a "High" priority be 

addressed within the next 5 years, listings with a "Medium" priority be addressed within 5-10 years as resources allow, and listings with a "Low" priority be addressed within the next 10 years.
