**Study Horizon:** February 2003 - September 2003 using 50 Historical
Streamflows (1929-1978) and Kuehl-

> Moffitt volume runoff forecasts. January generations taken from a
> study initialized to January 1 which operated to Bonneville flows of
> 125 kcfs for Chum.

**50-Year Treaty Storage Regulation (TSR)**

-   5.1/2.08 Mica/Arrow flood control split, Standard Libby and VARQ
    Horse Flood Controls, No shift at Dworshak, Brownlee and Coulee

-   Initialize Canadian and US project elevations to Dec 20, 2002
    Official TSR

-   All project operating requirements, loads, and resources based on
    the OY03 Detailed Operation Plan (DOP)

**50-Year Actual Energy Regulation (AER)**

-   5.1/2.08 Mica/Arrow flood control split, VARQ Libby and VARQ Horse
    Flood Controls, No shift at Dworshak, Brownlee and Coulee, With
    Adjustment to Coulee for Power Draft

-   Initialize Canadian projects to TSR and US project elevations to Dec
    23, 2002 Official AER

-   Canadian project operation based on the 50-Year TSR

-   All US project operating requirements, loads, and resources based on
    the OY03 Pacific Northwest Coordination Agreement (PNCA) Data
    Submittal

**50-Year Operational Regulation (OPER)**

-   3.6/4 Mica/Arrow flood control split, VARQ Libby and VARQ Horse
    Flood Controls, No shift at Dworshak, Brownlee and Coulee, With
    Adjustment to Coulee for Power Draft

-   Initialize Canadian to TSR, Non-Federal US project elevations to Dec
    23, 2002 Official AER and Federal projects to projected elevation
    from 1-8-2003 D30

-   Arrow initialized to 375 ksfd above the February 1 TSR content
    (includes LCA return, Flow Shaping Agreement and Special Treaty
    Storage)

-   Coulee initialized to 1283.0' for February 1

-   All Non-Federal US project operations and Duncan based on 50-Year
    AER

-   All Federal projects and Mica and Arrow operating assumptions
    described below.

-   Non-treaty storage was modeled as adjustments to Mica' outflow (see
    below)

**Project Operations**:

**[Mica:]{.underline}** TSR operation + NonTreaty Storage

> **[Arrow:]{.underline}** Arrow Total VECC method
>
> Special storage release of 190 ksfd in February
>
> LCA provisional draft (from December) of 28 ksfd returned in March
>
> January Flow Shaping storage of 213 ksfd to release in February and
> March
>
> February 1 initial content = TSR + 190 ksfd - 28 ksfd + 213 ksfd
>
> Draft up to 400 ksfd at Arrow in March to smooth Feb and Mar flows and
> reduce Apr1 outflows
>
> 1 maf Flow Aug stored at Arrow only in years when GCL returns to April
> 10 Flood control
>
> February and March minimum flows = 5 kcfs;
>
> May and Jun Qmin = 15 kcfs \-- Goal to smooth flows for Trout in BC
>
> On TSR April 15 through July 31
>
> No Trout Spawning modeled
>
> **[NTS:]{.underline}** No NTS storage in April
>
> Store in May and June as Arrow's outflows permit (Qmin = 15,000cfs)
