<br />at the toe of the dam Seepaqe was noted to be emerqinq in two separate locations The location on the riaht was producinq a seepaqe flow
<br />of 5 apm. Approximatelv 20 feet to the left a second location was observed to be aroducina 2 qpm The area below the toe is overqrown
<br />with cattails and willow brush. Releases from the outlet combined with see a e make the toe area wet and bo with considerable wetland
<br />veqetation. (39) Some minor seepaqe into the outlet stillinq basin was noted The seepaqe appears to be abutment seepaqe which enters
<br />the stillinq basin alona a construction ioint. The D/S slope and qroins were firm and drv• however the extensive willow qrowth and constant
<br />pondinq of water at the toe (due to qate leakaqe) make it difficult to adepuatelv assess seepaqe conditions

<br />with the downstream va{ve an undesirable mode of o eration which results in the ressurization of the outlet conduit. The Owners intend to
