<br />Dallas Creek Project: Ridgway Dam Em-
<br />bankment topped out July 23, 1986. Work
<br />on the rivel outlet works and instrumenta-
<br />tion continued. Water started lilllng be-
<br />hind the dam in early 1987. The reservOIr
<br />will11ave a surface area 01 1,030 acres.
<br />
<br />Construction tOlallng $19.6 million was
<br />completed
<br />
<br />Seedskadee Project: Spring runoll into
<br />Fontenelle Reservoir in southwestern
<br />Wyoming was 167 percent of normal. The
<br />dam"s outlets were operating at maxi-
<br />mum capacity but the Inllows still ex-
<br />ceeded the outlet capacity. The high run-
<br />011 swept debris Into the reservoir.
<br />partially clogging the trash racks of the
<br />outlet works. Divers were enlisted to diS-
<br />lodge the debris which was curlaillng Ihe
<br />planned releases flam tile reservoir. The
<br />oullet works were closed during the div-
<br />ing operation
<br />Salety 01 Dams work on the test section
<br />01 Fontenelle Dam started in 1985. The
<br />work is not lunded by tl1e CRSP. The
<br />results ot this contract. currently valued
<br />at $6.7 million, will determine how the
<br />final repair 01 tl1e dam will be accom-
<br />plished. The work was 95 percent com-
<br />plete by the end 01 H1e liscal year. As a
<br />result of the low reselvolr elevation, Ihe
<br />powerplant at Fontenelle is not In use.

<br />Navajo Storage Unit: Investigations,
<br />which were completed In 1984. into seep-
<br />age at Navajo Dam Ilave been underway
<br />Since it first filled. Subsequent investiga-
<br />tive reports recommended that allhough
<br />no damage to the core 01 the dam has
<br />been idenlllled, a construction program
<br />be initiated to conlrol tile seepage. A con-
<br />lract lor the construction 01 a concrete
<br />diaphragm wafl in the lell abutment was
<br />awarded in September 1986 for
<br />$9,756,000. A series 01 pipes, drains and
