Barr Lake Spillway <br />Similar to Milton Reservoir, the SEO's spillway evaluation at Barr Lake indicated that <br />its spillway needs to be enlarged to meet State standards. <br />Alternative No. 1- No Action: This alternative was considered unacceptable because by <br />not increasing the capacity of the spillway, the Company would be ignoring the <br />requirements of the SEO and Barr Lake would likely be put under a fill restriction. <br />Alternative No. 2(SELECTED) - Enlarge the Spillway with a Concrete Control <br />Structure and a Downstream Soil Cement Channel: This alternative involved <br />increasing the spillway length.

The approach and hydraulic <br />control section of the spillway will be constructed out of concrete. The concrete slab will <br />
