Lakehead University will be hosting an open house for residents and campers of the Cloud Lake area on Sat., May 30th from 10 am to noon at Blake Hall (71 Blake Hall Rd., Neebing, ON)(map).

Over the summer months, scientists from the university will be examining the effects of nutrient inputs to the lake in terms of the total phosphorous production. They will also be examining the effects of these nutrients on the local aquatic ecosystem.

In recent years, user groups and resource managers have noted declining ecosystem conditions in Cloud Lake. A decline in water quality has been observed as indicated by algal blooms, increased turbidity, and elevated phosphorus concentrations. In addition, aquatic invasive species—rusty crayfish and smelt—have been introduced, and the quality of the fishery has decreased. There are several potential causes for the decline in ecosystem health, but field studies have been limited to single data points without the benefit of a planned and coordinated effort to gather data over multiple seasons. Lakehead University has agreed to collect baseline data this summer to better define the problem and to understand the environmental factors that may be affecting the watershed.

This open house is an opportunity for residents to meet the researchers, ask questions and provide input/observations on the lake conditions. Free refreshments will be provided.

Update on Flows From Lake Superior at Sault Ste. Marie – May 1, 2015

The following information was received from the Lake Superior International Board of Control, a division of the International Joint Commission:

Update regarding the gate setting of the Compensating Works [the structure controlling L. Superior levels at Sault Ste. Marie, Ontario] expected in May.

 Providing ice conditions allow it, the Compensating Works are expected to be set to the equivalent of approximately two gates fully open tomorrow, Friday, May 1st.  This will be achieved by partially opening twelve gates (Gates #3 to #14) a total of 31 cm (12 in.) each.  Anglers should remain cautious of changing flows and water levels and the potential for hazardous ice conditions in the St. Marys Rapids.  Note that conditions will be reassessed and the gate setting may be increased again later in the month, once ice conditions improve.  We will advise of any changes at that time.

 As usual, there will be no change to Gate #1, which supplies water to the channel north of the Fishery Remedial Dike.  Furthermore, Gate #2 will remain closed for the time being in order to provide lower velocities and potential angling opportunities along the northern portion of the main rapids.  This is something that’s been suggested in the past and we’d welcome feedback on this approach.
