Pot, Fire and Weir lakes, all built in by the Provo Reservoir Company, are indicative of the renewed local interest in reservoir-building sparked by the drought of They are historically significant as among the last examples of private reservoir construction in the Provo River drainage. The smallest of the dams in the Bonneville Unit, the Pot Lake Dam displays typical small-scale earth-fill construction. It stands today essentially unaltered and intact.

UT-41-I (Page 2) HISTORICAL INFORMATION A picturesque body of water with a rocky shoreline dotted by scattered timber, Pot Lake at four acres is the smallest of the fifteen reservoired lakes at the headwater of the Provo River. Late in the Provo Reservoir Company applied for a special use permit to impound water on the lake for irrigation storage. In May the National Forest Service granted the permit. A small dam across the lake's natural outlet was constructed that year. Sixty feet long and only 8 feet high, the Pot Lake Dam consists of a clay core, covered with compacted earth fill and faced with hand-placed rock riprap. The outlet is a 12" diameter corrugated iron pipe with an inclined 10" Hardesty sliding headgate.

It is proposed that the dam be removed entirely to return the lake to its natural level.
