Hydraulic Analysis: Phase II contains these 3 items: a) Lake refill study will calculate potential refill times based on the last 35 years of precipitaiton records. Probability plots of refill times will be prepared to assess variability. b) Downstream impact study will include analysis of downstream floodplain impacts, analysis of potential downstream river bed scour and analysis of potential impacts to Lower Phantom Lake. c) A groundwater model will be developed by USGS for Eagle Spring and Lulu Lakes. The project deliverables will be an electronic version and paper copy of project report containing the following elements: 1) lake refill study; 2) analysis of downstream impacts due to proposed lake drawdown; and 3) analysis of impacts to local wells. Scope change amendment #2 in May 2005 was to add a specific line item for a sediment and coring dating study for $2000. Scope change amendment #3 in July 2005 was to add a specific line item for development of a marl budget for Eagle Spring Lake for $4,080 The "downstream impact" line item was adjusted down $6080 on September 27, 2005 to account for this.
