GEORGETOWN LAKE UPDATE
Georgetown Lake water surface elevation was at 6428.26 feet to end September. That elevation is about one-tenth of a foot higher than the long-term and short-term average. The lake lost 714 acre feet during September which amounts to an average of 12 cfs. Average September outflow measured at the USGS gaging station was 27.2 cfs, therefore net lake inputs for the month averaged 15.2 cfs, which is 69% of the long-term norm. Outflow is currently set at about 14 cfs, and the lake is rising slightly.
September precipitation measured 1.80 inches at Peterson Meadows, which is 98% of normal, and Water Year 2016 (ending September 30) registered a total of 27.6 inches at Peterson Meadows, which is 105% of normal precip. As we enter the new water year, conditions look quite good at the lake.
The NWS forecast calls for tough weather at the lake this week, with good chances of precipitation including snow and nighttime temperatures below freezing. The NWS has issued a Winter Weather Advisory for the area, which is great news depending on your perspective and planned activities. For the long term, the current CPC forecast shows elevated probability of above-normal precipitation through March, and elevated probability of above-normal air temperatures for much of the winter.
Since last month saw 69% of normal lake inputs, I ran the model using that figure going forward. If the weather forecast pans out, the precipitation this week alone could substantially alter that low (69%) input figure. Also at this time of year, lake evaporation and plant transpiration decrease dramatically. So in the short term, it is likely that inputs will exceed the 69% of normal.
The attached graphic shows model output based on 14 cfs outflow through the winter, and 69% of normal inputs. It’s a good looking scenario. Lake freezeup is typically in late November, and the model shows a water level of 6428.36 feet which is right where it should be heading into winter.
