Georgetown Lake Homeowners Association

  1. WaterWe are on a committee that advise Granite County on lake management.  We cosponsored and participated in a Clean Lake Study to assure our lake is healthy. It Is!

  2. Zoning: Homeowners at the lake wanted a “soft touch” zoning or development rules so we guided that process through meeting and hearings until that was achieved. ( 3 years). 

  3. Wildlife ManagementWe work closely with FWP and other groups to address wildlife issues in our area. This includes public presentations and promoting good management practices such as bear proof garbage cans. 

  4. Volunteer Fire Department: We support the Georgetown Lake Fire Department with equipment donations and funding for equipment for the Emergency Response Unit.

  5. Planning Board: We have had a member sit on the Granite County Planning Board to guide development at the lake.

  6. Meetings: GLHA holds two meetings at the lake every year to keep members informed of current issues. There are usually speakers from various agencies to inform us on topics of interest. 

  7. Watershed: GLHA has a representative sit on the Granite County Watershed Committee. This group is designed to preserve and protect the watershed including Georgetown Lake. They also promote maintaining our rural lifestyle. 

  8. Flow Gauges: GLHA also shares in the cost of maintaining a USGS flow gauge on Flint Creek. This measures the water coming out of Georgetown Lake on a real time basis. This enables us to monitor management of the reservoir by Granite County. 

  9. Membership: We welcome new members to help us with these endeavors. The cost of membership is $25. You can send a check to GLHA, PO Box 643 , Anaconda, Montana 59711. Include your address at the lake and for future mailings, email is appreciated also.

GEORGETOWN LAKE UPDATE – September 8, 2022

Current Lake Elevation    6428.18    (PROVISIONAL DATA from USGS gage 12325000)

The water surface elevation is slightly lower than average for September, based on 80 years’ worth of lake elevation data. 

Elevation and Inputs. Since July 31, 2022 the water surface has fallen from 6428.99 to 6428.18 feet. As is normal for this time of year, outflows exceeded all August inflows into the lake. The lake lost 2,261 acre feet of storage from July 31 to August 31.  Storage loss averages -36.6 cfs.  The lake was gaining less than the average monthly August outflow of 36.8 cfs, with total lake inputs equal to less than 1 cfs. The inflows were only 5% of normal for August. The inflows continue to be significantly less than normal for this time of year. Hotter temperatures in August likely contributed to increased evaporative loss from the lake surface which takes away from inflow.


In August, the Peterson Meadows SNOTEL site received 1.2 inches of precipitation (which is 100% of normal), and the Warm Springs SNOTEL site gained 1.7 inches (142% of normal).

Climate Forecast
The CPC climate forecast (created August 31, 2022) shows a good chance of higher than normal air temperatures and less than normal precipitation for September (which has held true for the first week of the month).  Hotter than average conditions are predicted to persist into October and November.  These forecasts are updated around the 20th of each month.

The current Weather Service forecast from the Missoula forecast office for Philipsburg, MT shows lows below freezing and increasing to the 40’s over the next week. Highs are predicted to be in the 60’s for the rest of the week, increasing to the 70’s and 80’s into next week. There is little to no chance of precipitation in the next 7 days.

Model Forecast
The water surface elevation sits at 6428.18 feet today, and I used a starting elevation of 6428.33 feet from the USGS gage for August 31. For this model run I used variable inflows for each month because it is unlikely that these very low inflows persist over the fall and winter. Based on the inputs calculated for August, I used a very low figure of 5% of normal in the model run for September (see next page). Inflows increased to 20% for November because lower temperatures and more precipitation usually contribute to higher flows. Inflows for the remainder of the model run were set to mimic last year. The inflow percentages for each month are shown at the bottom of the graph. The springs and the NF of Flint Creek were flowing at the end of August but not much (don’t have exact flow rates). So far in 2022, increased rainfall has not translated into increased inflows. For this model run, I included outflows from the agreement between Granite County and FCDAC to decrease flows from 30 to 15 cfs from September 15 to 28. Flows after September 28 return to 30 cfs.

Protecting Montana's Waters
John O'Bannon AIS Area Supervisor for Southwest Montana, with the Montana Fish Wildlife and Parks AIS Bureau, Presented a slide show on protecting Montana's lakes, rivers and streams from invasive mussels, snails and fish at the August Georgetown Lake Homeowners Association meeting and BBQ.  

For more information please contact:
John O'Bannon

To help stop the spread of invasive aquatic species:

1. Help spread the Clean, Drain, Dry message
2. Boats traveling on the Interstate should be inspected prior to launch
3. Aquarium dumping must be STOPPED! Aquariums fish and plants can cause serious damage to our lakes and streams.
