5 August 2020: CBI Mid-Summer Update

Our Courtesy Boat Inspection program is running like a well oiled bicycle this summer, thanks to an energetic and committed volunteer work force. We got a bit of a late start last year, but this year we started boat inspections on Memorial Day weekend and have managed to have volunteers at the State boat launch every weekend from 6 AM until 2 PM ever since. To date we’ve staffed 93 two-hour shifts for a total of 192.1 volunteer hours and have conducted 315 inspections. So far this year we’ve only found one plant on an inbound boat that turned out not to be invasive. State-wide there have been 4,312 shifts (most are two hour shifts but some are longer) and 54,815 inspections conducted and 1,616 plants were found, 67 of which have been identified as invasive plants. I’d say the program is working! You can look at the data directly using the 2020 Maine Courtesy Boat Inspection Dashboard. Select the Clary Lake Association from the “Select Organization” list to see our data. Continue reading

02 August 2020: July Water Level Chart Archived

7 Clary-Lake-Water-Level-July-2020

July 2020

I have archived the July 2020 Water Level Chart (at left). For the third month in a row we’ve managed to maintain a relatively stable water level despite mild drought conditions prevalent at the start of the month. The lake level fluctuated only 1.5 inches from low to high over the course of the month, starting out at -0.50 feet and ending the month with the lake level at -0.41 feet. A number of people have let us know that they think the lake level this summer has been about perfect. We were shy of the monthly average rainfall until two back-to-back squalls on July 30th dumped a little over an inch of rain and pushed our monthly rainfall total to 3.77 inches, a little over the average for July of 3.54 inches. Because of an extra dry June, we’re still 0.28 inches below average for this date.

Tropical storm Isaias is due to pass through Maine this coming Tuesday night into Wednesday, and it has the potential of dropping several inches of rain, if not more. We’ve temporarily increased outflows so as to create a little head space to accommodate the anticipated storm water runoff. We don’t expect any significant flooding or a major change in the water level when it’s all said and done. Continue reading

6 May 2020: Browntail Moth Season Ahead!

Any day now, over-wintered Browntail Moth caterpillars will start to emerge from their tree-top leaf nests and start eating. Last year they did a great job (?) of defoliating Oak trees around Clary Lake and spreading their poisonous hairs all over the place. The south shore of the lake by Hodsdon Lane was particularly hard hit. I haven’t seen near as many Browntail moth nests in the trees around my house this spring, making me think this year the infestation may be less severe than last year, but it still pays to be alert to the risk they pose to our trees and our health. According to the newly published Browntail Moth Risk Map (PDF | 2.44 MB) however, the towns of Whitefield and Jefferson still have a HIGH Browntail Moth Risk Rating. Continue reading
