GLHA 2016 Summer Barbecue

August 27, (Saturday) 12:00 Noon

Location: Fire Hall Behind 7 Gables

_________________________________________________

Greetings, as of this writing, lake water level is looking good and on track for July. Spring runoff was strong and as predicted by Dave Amman at the DNRC, we saw full pool @6429.5ft in late May. Currently the lake water level is stable at 6429.35ft. Outflows are 31cfs. Recent rains have given us a nice boost in levels. Fishing has been good but it looks like lake weeds could become a problem later this summer for our boat props.

Our Georgetown Lake Fire Dept. has a revised upward rating in a recent Public Protection Classification (PPC) Survey. This should result in lower insurance premiums for lake properties in the range of 10%. You can read the report at our georgetownlakehomeowners.com website. Granite Co. and the Forest Service are working together on a new proposal for work on the Lower Lakeshore Road. 

The work would begin in 2018 with the object of bringing this section of Forest Service dirt road into compliance with county standard and under full county control.

All association members and friends are welcome to our barbecue lunch. The Board thanks you for your participation.

UPDATED August 5, 2016

GEORGETOWN LAKE UPDATE   

Today the lake level sits at 6429.07 feet and outflows are showing 31 cfs. Outflow right at the dam is likely 30 cfs but the creek picks up some minor inflows between the dam and the weir pond. 

The lake level on July 31 was 6429.18 feet, which is almost 3 inches above the average July 31 level since 1999.  Average outflow for July was 30.2 cfs.  Crunching the numbers reveals average July lake inputs of only 19.6 cfs, which is 45% of normal.  March through May saw slightly above-normal precipitation at Peterson Meadows SNOTEL site, followed by very low June precipitation (1.2 inches = 32 percent of normal).  Good storms in July dropped 1.7 inches, 189 percent of normal.  Reservoir operations have been excellent, and Georgetown Lake is faring better than the rest of the state.

Looking forward, the CPC forecasts above-normal air temperatures and below-normal precipitation for August, warm and average precipitation for September, then switching to above-normal precipitation and colder for October through March. The CPC currently forecasts a possible La Nina event beginning this fall and lasting through the winter.  This would typically indicate above-normal precipitation for western Montana. We will see.

If outflow is held at 31 cfs through August, using 45% of normal inputs in the GTL model predicts an August 31 lake level at 6428.73 feet.  If outflow was increased to 47 cfs for August 10 through August 19, then reduced back to 30 cfs for the rest of August, outflow for the month would average 35.8 cfs.  The increased outflow would reduce reservoir contents by an additional 317 acre feet, which translates into about one tenth of a foot (1.2 inches) of additional drop in water surface elevation, finishing August at 6428.63 feet.

The attached model output illustrates end-of-month elevations assuming lake inputs (groundwater, surface water, precipitation) remain at 45 percent of normal; that outflow is increased to 47 cfs for 10 days in August, then returned to 30 cfs. I remind folks to focus in on model predicted lake levels for the next few months only, not next year. The model runs on lake inputs which are currently 45% of normal, but which change constantly with precipitation and air temperatures.

Thanks, Dave
