The reclaimed ponds should be labeled from west to east on the north side of the river, 1, S, <br />and 4, and nn the south side of the river from west to east, 2 and 3, It is my understanding <br />that there was a Technical Revision some yews back to change the numbering on the original <br />1983 Reclamation Plan. <br />2. Hall Irwin commits to having a representative from Sinclair Pipeline Company present on <br />site during the spillway construction. <br />The 1998 flood inundated most ofthe three ponds on the north side of the river, however the <br />only evidence of significant damage occurred where flow was concentrated between ponds 5 <br />and 4. This damage will he mitigated and controlled in the future by the construction of a <br />spillway. All other Locations where water rnters and exits the ponds seem to be able to <br />withstand the erosional forces of the river and it is not thought that additional spillways are <br />necessary. <br />Please feel free to call i f you have any questions or additional comments.
