Bear Lake Preservation Advisory Committee April 12, 2004 Introductions were made A discussion of the Committee’s structure and how the organization
should operate followed. It was agreed that the BLPAC meeting was to be held at least annually
and that the following years meeting would be set at the current meeting.
Some factors to consider were the April 10th date for setting the annual
Irrigation Allocation and the general lake level. eg. Later for low lake
levels to get a better forecast or earlier if considering pumping for
possible downstream flooding. The three co-chair format was retained. Co-chairs are: PacifiCorp - Connely Baldwin, Bear Lake group – Claudia Cottle and Irrigators – either Marcus Gibbs or Charles Holmgren were volunteered since neither were present to defend themselves. Dan Davidson represented the Irrigation interests. The responsibility for organizing the meetings will rotate with PacifiCorp (Connely Baldwin) for 2004, the Bear Lake group for 2005 and the Irrigators for 2006. The goals of the Preservation Advisory Committee were read and a discussion
of several goals followed. A change in the methodology used in forecasting stream flows should give us more realistic data. Tom Perkins, NRCS in Portland, works monthly with Randy Julander in Salt Lake using snow pack data to arrive at stream flow forecasts. They had been using naturalized flows at Stewart Dam which did not account for upstream diversions. They will now use observed flows. Water conservation was discussed. Merlin asked if the Committee could have any impact on the conservation of water by the Irrigators. There was a discussion on reductions or savings that could be used in future times of need. What can we (as a group) do to protect some of the water when it gets back into the lake? David Cottle will work with PacifiCorp hydrologists and Jack Barnett to compile comparable data showing how much water the Bear Lake Settlement Agreement has saved and the additional amounts that the Irrigation Companies have voluntarily not used. It was guestimated that enough water was conserved so that last years irrigation season was possible. As a group, we must look ahead to see what conservation efforts are possible. Such things as lining canals to reduce transportation losses, pursuing additional storage, automating flow data and diversions and determining better timing of deliveries are a few of the areas we should pursue as a group. The co-chairs will form a smaller subcommittee to redefine our goals. Exhibit A of the Amended Settlement Agreement was discussed. The Bear Lake capacity table (Column B) appears to have discrepancies in that as lake elevation decreases, each foot of water has a different volume. In an effort to be as accurate as possible and to be dealing with realistic volumes, PacifiCorp hydrologists will check their original lake volume data (capacity curve). It may be desirable to get a more up to date, satellite mapped data. The Est. Annual Allocation (Column E and footnote 5) is derived by using
the Estimated Lake Elevation rounded to the nearest tenth and then interpolate
the Estimated Storage Water Available. This years Irrigation Allocation is 85,000 acre feet. That is about ½ of last years allocation. There will be a press release and letters to the canal companies. Due to the difference in elevation between the lake and the outlet canal,
the Lifton pumps can only pump at 1100 to 1200 cfs when the lake is at
5905.50 ft. This rate may decrease to about 500 cfs as the lake drops.
At 1000 cfs the Irrigators have about 45 days of water. At 500 cfs that
will be spread out over 90 days. PacifiCorp, the Irrigators and Bear Lake Watch will still protest new water applications. Vista Grande application was discussed. PacifiCorp sent them a letter agreeing to one extension. In the past, PacifiCorp has started water releases from Bear Lake based on conditions at Cutler Reservoir. Since the supply is so tight this year, PacifiCorp will hold meetings with the Canal Companies to see how they want to take their water and if a new method can be used to establish when pumping begins. PacifiCorp will send a letter to Will Atkins on how water is to be divided. The Amended Bear Lake Settlement Agreement will be included in the minutes of the Bear River Commission meeting next week. The BLPAC will suggest that the Commission help sponsor a Bear Lake Water Quality Symposium to be held this Fall. A Fall meeting of BLPAC will be determined at a later date by
the co-chairs. |
