About this file
This file is a set of drawings related to a federal solicitation for the Yose Canyon Dam Removal project. The solicitation was issued by the Bureau of Land Management under number 140L0623R0019 to solicit proposals for removing the Yose Canyon Dam and restoring the natural waterway. Key details of the project include removing an existing dam structure, restoring the riverbed and banks to a natural state to allow free-flowing water once more, and remediating any environmental impacts from the dam's prior existence. The 26MB file of drawings provides potential offerors with detailed technical specifications and diagrams to inform their responses for this dam removal and environmental remediation work. The response deadline and planned award date are not specified in the available information.

IN 2019, THE BLM COMPLETED A WATERSHED ASSESSMENT AND RESTORATION PLAN FOR THE LABARGE WATERSHED IN SUBLETTE AND LINCOLN COUNTIES IN SOUTHWEST WYOMING. THE STUDY AREA INCLUDED APPROXIMATELY 250 SQUARE MILES IN THE DRY BASIN DRAW, DRY PINEY CREEK AND BIRCH CREEK WATERSHEDS. THE SUBJECT WATERSHEDS ARE LOCATED WITHIN AN EXISTING 100-YEAR OLD OIL AND GAS FIELD WITH MORE THAN 1,800 ACTIVE WELLS OF VARYING AGE AND CONSTRUCTION. SURFACE DISTURBANCE FROM ROAD AND DRILLING PAD DEVELOPMENT HAS CONCENTRATED STORMWATER RUNOFF AND CAUSED ACCELERATED EROSION OF THE HIGHLY SENSITIVE
LANDSCAPE, RESULTING IN EXCESS FINE SEDIMENT DELIVERY TO THE UPPER GREEN RIVER.
THE LABARGE WATERSHED RESTORATION PLAN PRIORITIZED 19 SITES FOR RESTORATION INCLUDING SITE BLM-33 YOSE CANYON DAM. THE PURPOSE OF THIS PROJECT IS TO REMOVE AN EARTHEN IMPOUNDMENT AND RE-GRADE EXISTING INCISED CHANNELS TO RE-ESTABLISH A BROAD EPHEMERAL DRAW WITH NUMEROUS STABLE MICRO CHANNELS. THE PROJECT GOAL IS TO PREVENT FURTHER DEGRADATION AND EROSION WITHIN THE STUDY AREA WATERSHEDS AND RE-ESTABLISH, MAINTAIN AND/OR IMPROVE EPHEMERAL CHANNEL FUNCTIONS. THE FOLLOWING OBJECTIVES WERE DEVELOPED COLLABORATIVELY BY BLM AND THE PROJECT STAKEHOLDERS TO GUIDE RESTORATION ACTIONS:
· ADDRESS THE PROCESSES RESPONSIBLE FOR LANDSCAPE DEGRADATION;
· PROTECT RESOURCES WITHIN THE PROJECT WATERSHEDS INCLUDING INFRASTRUCTURE, ECONOMIC RESOURCES, PRIVATE LAND, WATER RESOURCES AND ECOLOGICAL
RESOURCES;
· MANAGE SEDIMENT DELIVERY TO THE UPPER GREEN RIVER; AND
· IDENTIFY OPPORTUNITIES FOR CONSERVATION AND STEWARDSHIP.

1. THE CONTRACTOR SHALL VERIFY EXISTING CONDITIONS IN THE FIELD PRIOR TO CONSTRUCTION. IF NECESSARY, ADJUSTMENTS TO THE DRAWINGS WILL BE MADE AS DIRECTED BY THE ENGINEER.
2. TOPOGRAPHY SHOWN ON THE DRAWINGS IS BASED ON PHOTOGRAMMETRY AND GROUND SURVEY DATA. GROUND SURVEY WORK WAS PERFORMED IN AUGUST 2020 BY JACKOLA ENGINEERING AND ARCHITECTURE PC USING
SURVEY GRADE GPS. PHOTOGRAMMETRY WAS PERFORMED BY RIVER DESIGN GROUP, INC. IN OCTOBER 2019 USING AN UNMANNED AIRCRAFT SYSTEM.
3. UTILITIES IDENTIFIED ON THE DRAWINGS ARE APPROXIMATE AND DO NOT REPRESENT ABSOLUTE HORIZONTAL AND VERTICAL LOCATIONS. THE CONTRACTOR SHALL COORDINATE WITH THE APPROPRIATE UTILITY LOCATE
SERVICE PRIOR TO CONSTRUCTION TO IDENTIFY UTILITY LOCATIONS.

EXISTING CONDITIONS
YOSE CANYON DAM IS LOCATED ON AN EPHEMERAL DRAW IN THE BIRD DRAW WATERSHED. THE SITE CONSISTS OF AN EARTHEN STOCK POND IMPOUNDMENT THAT HAS BEEN FLANKED BY AN ADVANCING KNICKPOINT. OVER TIME, THE STOCK POND HAS FILLED WITH SEDIMENT DELIVERED BY THE WATERSHED AND BECOME ELEVATED ABOVE THE NATURAL GRADE OF THE SURROUNDING VALLEY FLOOR. DUE TO THE DEPOSITION BEHIND THE STOCK POND, THE DAM FAILED BY ALLOWING FLOW TO FLANK THE NORTHERN EDGE OF THE DAM. THIS CREATED A LARGE KNICKPOINT AND CHANNEL AVULSION THAT MIGRATED
AROUND THE DAM. THE AVULSION CREATED A NEW CHANNEL OVER 1,000 FEET LONG, ERODING
ROUGHLY 19,500 TONS OF SEDIMENT. A NEW KNICKPOINT HAS FORMED FROM A TRIBUTARY DRAW THAT IF UNMITIGATED WILL RESULT IN A SIMILAR SCALE OF SEDIMENT RECRUITMENT. SEDIMENT
DELIVERY WILL BE EXACERBATED BY EROSION OF THE MATERIAL STORED UPSTREAM OF THE
IMPOUNDMENT AND FROM THE MATERIAL IN THE IMPOUNDMENT. UP VALLEY OF THE KNICKPOINT IS AN
EPHEMERAL DRAW WITH NUMEROUS MICROCHANNELS WITH MATURE SAGEBRUSH COMMUNITIES.

RESTORATION STRATEGIES AND ACTIONS
THE PURPOSE OF THIS PROJECT IS TO REMOVE AN EARTHEN IMPOUNDMENT, RE-GRADE EXISTING INCISED CHANNELS TO RE-ESTABLISH A BROAD DRAW WITH NUMEROUS STABLE MICRO CHANNELS AND CONSERVE AN EXISTING DRAW THREATENED BY AN ADVANCING KNICKPOINT. REMOVAL OF THE IMPOUNDMENT AND STORED SEDIMENT WILL REDUCE DOWNSTREAM SEDIMENT DELIVERY. RE-GRADING THE DRAW AND INCISED CHANNELS TO A STABLE REFERENCE SLOPE WILL REDUCE STREAM POWER DURING PEAK FLOWS BY SPREADING OUT FLOW OVER A GREATER AREA. THE ADVANCING KNICKPOINT WILL BE ELIMINATED BY FILLING THE INCISED CHANNELS WITH EXCAVATED MATERIAL. SAGE BRUSH AND ROCK WILL BE SALVAGED DURING EXCAVATION AND USED FOR ROUGHNESS TO TEMPORARILY STABILIZE RE-GRADED SURFACES. PROJECT ELEMENTS
INCLUDE:
· REMOVE THE FAILED EARTHEN DAM;
· ELIMINATE THE ADVANCING KNICKPOINT BY FILLING THE EXISTING INCISED CHANNELS WITH EXCAVATED MATERIAL FROM
THE STOCK POND AND DAM;
· EXCAVATE TO RE-ESTABLISH A BROAD DRAW WITH NUMEROUS DISPERSED MICRO-CHANNELS;
· PERFORM MICROCHANNEL MODIFICATION ON AVULSION CHANNEL TO MINIMIZE RISK OF INTERACTION WITH THE DRAW;
AND,
· USE SALVAGED SAGE BRUSH AND ROCK FOR FLOODPLAIN ROUGHNESS TO TEMPORARILY STABILIZE RE-GRADED
SURFACES.

THE GOAL OF THE RECLAMATION PLAN IS TO CREATE A SELF-SUSTAINING AND DIVERSE NATIVE PLANT COMMUNITY. THIS PLANT COMMUNITY WILL HAVE DENSITY AND COVER SUFFICIENT TO CONTROL EROSION, LIMIT NON-NATIVE PLANT INVASION, AND RE-ESTABLISH WILDLIFE HABITAT AND FORAGE PRODUCTION. THE FOLLOWING SUITE OF TREATMENTS WILL PROMOTE THE SHORT- AND LONG-TERM STABILITY OF THE PROJECT AREA. THE ROUGHNESS TREATMENTS PROVIDE IMMEDIATE EROSION PROTECTION FROM SURFACE WATER FLOW, WHILE THE REVEGETATION PROMOTES LONG-TERM GEOMORPHIC STABILITY AND ECOLOGICAL RECOVERY.
RECLAMATION DESCRIPTION
· SEED MIX MUST BE SUBMITTED FOR REVIEW AND APPROVED BY THE ENGINEER.
· BROADCAST SEEDING SHOULD BE USED TO DISTRIBUTE SEEDS EVENLY THROUGHOUT THE SITE.
· IMPLEMENT SEEDING AFTER ROUGHNESS TREATMENT CONSTRUCTION.
