Jess Dam and Lost Creek Reservoir

William L. Jess Dam is situated on the main stem of the Rogue River, about 28 miles northeast of Medford, Ore., in a timbered canyon on the Rogue River. The Lost Creek Reservoir and features public access areas, parks, boat ramps and 30 miles of scenic trails.

Jess Dam at Lost Creek is a 327-foot-high rockfill embankment structure with a gated spillway. Jess Dam was the first of three multi-purpose storage projects finished in the Rogue River Basin project. 

Authorized primary purposes include flood risk management, water supply, water quality improvement, fish and wildlife habitat enhancement and recreation.

In 1996, Congress renamed Lost Creek Dam in honor of William L. Jess, a strong advocate for multiple uses of impounded waters and one of the founders of the Rogue Basin Association, established in 1955.

Jess Dam Operations

Lost Creek / William L. Jess Dam and Reservoir

The William L. Jess Dam and intake structure is a 327-foot-high rockfill embankment structure. Construction began in 1967 and the lake began filling in February 1977. Runoff from a drainage area of 674 square miles pools into Lost Creek Lake. The lake provides 465,000 acre-feet of total storage and has an area of 3,430 acres when full.

A regulating outlet tunnel, power penstock, and intake tower with multi-level intakes are located in the dam's right abutment; a gate-controlled concrete chute spillway is located in the left abutment. The powerhouse's generating capacity of 49,200 kilowatts comes from two 24.6-megawatt generators.

Environmental concerns prompted the Corps to construct an innovative multi-port intake tower, allowing operators regulate the temperatures of water released from the lake. Lost Creek’s intake structure combines lake water from different depths in a mixing chamber before releasing it downstream, regulating the water temperature and improving conditions for fish migration and survival in the Applegate and Rogue rivers. 

The returning fish are collected just below the dam and transported to the Cole M. Rivers Fish Hatchery, located just downstream of William L. Jess Dam on the Rogue River, for spawning. Later, juveniles are released into the Applegate River to maintain the runs.

SUBJECT: Commander’s Policy Letter #19, Geocaching Within Portland District Boundaries



1. Purpose. Geocaching may be allowed on public lands managed by the U.S. Army Corps of Engineers in accordance with the Code of Federal Regulations Title 36 (CFR 36) and any applicable state or local rules and regulations, provided the activity is conducted in an unobtrusive manner. Geocaching can be an appropriate and compatible recreational activity on public land and water, as long as common sense guidelines are followed. Some Corps projects have used the popularity of the sport as an innovative tool to distribute information, such as water safety, in geocaches on Corps-managed lands.



2. Definition of Geocaching. Geocaching is an outdoor adventure activity for users of global positioning systems (GPS). Individuals and organizations set up geocaches (caches) all over the world and share their locations, often through the Internet. Numerous web sites are available, with one of the most popular being http://www.geocaching.com/. GPS users can then find the caches through published coordinates and site descriptions. Most commonly, a geocache is an object or container holding small objects for exchange. The finder may remove the enclosed "prize" and leave another, sign a logbook, or utilize a number of variations. Some "caches" are simply locations with unusual vegetation or unique land features the cache owner wants the cache hunter to experience (virtual caches). There is also a derivative form of the sport that searches for published coordinates of an existing historical monument, plaque, or benchmark.

While geocaching has become the standard name for the sport, other terms include Navicaching, GPS Orienteering, GPS Stash Hunt, and Benchmarking.



3. Policy. In accordance with 36 CFR 327.19 or 327.21, District Engineers, or their designees, may develop permit systems or policies to track and/or control placement of geocaches on project lands, provided this use does not conflict with project missions or security. Simplicity and ease of compliance should be emphasized. Information needed from the proposed geocache owner will include the cache coordinates (location), his/her name, and his/her address and phone number. The intent of collecting this information is to keep track of the location and number of caches on the project and to contact the owner if the cache needs to be removed. During application, the project should ask the proposed cache owner to provide a current picture form of identification with an address to confirm the applicant's identity. This information is voluntary; however, the applicant’s request can be denied for failure to comply with the information request. The project is required to store this information in a secure manner. Geocache objects or containers should be clearly identified as such when placed on public lands. Transparent containers are required, due to homeland security issues. Caches should not contain alcohol, illicit, or other inappropriate materials. It is the due diligence responsibility of the Project Operations Manager to work with the cache owners and jointly conduct periodic cache inspections to insure they are not being used for illicit and/or inappropriate purposes.

a. Individuals or groups that participate in geocaching activities on Corps property must be responsible for coordinating these activities with the Portland District, to help prevent potential conflicts with management activities (i.e., controlled burns, timber sales, planting, etc.)



4. Restrictions. It is the due diligence responsibility of the Project Operations Manager to establish designated areas where geocaching will be allowed and other areas where it will be restricted. Geocaching activities will not be allowed to occur in restricted areas where there could be conflicts with project missions, project security, or the safety of the general public.

Examples where geocaching would not be allowed include but are not limited to:

a. In designated restricted areas.

b. lf the cache, directly or indirectly, would negatively affect ecologically, environmentally, or socially sensitive areas (i.e., threatened or endangered species, critical habitats, cultural resources, tribal lands without consent, etc.).

c. In areas with potential safety risks, such as unstable banks, cliffs, or other hazards.

d. Where geocaching activities may interfere with established public uses, such as boat launching, picnicking, swimming, etc.

f. Where geocaching activities may interfere with the operation or security of the project.



5. Management Considerations. Management considerations at individual projects may require other permanent or temporary measures to ensure that geocaching activities are compatible with other project uses. For example, a project may need to prohibit geocaching during active management in an area for timber harvest, prescribed burning, hunting, or other wildlife management activities. Some projects may want to encourage and actively participate in geocaching activities to promote the Corps message in a positive way.

a. In certain instances, it may be necessary to issue a Special Event Permit in compliance with Title 36, 327.21. Conditions that may warrant the need for a Special Event Permit may include one-time activities that are publicly advertised, commercial in nature, involve large numbers of participants, provide cash prizes or other significant awards, or may potentially conflict with other uses of an area, etc.

b. If a cache must be removed from public lands for operational, safety, environmental, cultural, or other reason, a reasonable effort should be made to contact the cache owner and request removal. If the owner cannot be found, or the cache is not removed within a reasonable time, the cache may be removed and impounded as abandoned property, under 36 CFR 327.15.



6. Summary. In general, geocaching can be a fun and appropriate recreational activity at Corps projects, provided the security or missions of the project are not compromised. It provides an opportunity for positive interactions and partnerships with local groups involved in this activity.

Monitoring of web sites, communication and participation with these groups can form healthy relationships with benefits to all involved. Working with these groups can prevent problems and promote the Corps as a willing partner. Regulation should be based on common-sense needs of specific projects or areas, with a minimal permitting burden on the recreating public.

These five steps will help you to anchor safely:

  1. Use anchor lines that are 5-7 times the depth of the water.
    1. Use a float for the anchor line to serve as a buffer and to reduce the risk of getting the anchor line tangled in the propeller.

    2. Lower, do not throw, the anchor to avoid tangles in the line.

    3. Anchor only off the point of the bow. Anchoring off the stern or the side will capsize your boat.

  2. Power upstream of anchor before retrieving it. Maintain position in line with the flow of the current while retrieving anchor. Turning cross-wise to the current increases the risk of capsizing.

  3. Rivers can become turbulent with little or no warning. You are advised to wear a Coast Guard-approved Personal Flotation Device at all times. Also, take precautions against hypothermia. River temperatures can range from 70 degrees in the summer to near freezing during the winter.

  4. River users are reminded that although it is legal to anchor in the channel, it is illegal to block the right-of-way of a vessel that is restricted to using the channel.

  5. Five blasts of the horn signify danger, and you must take action to avoid that danger.

Day-use fees, including boat ramp and dump station fees, will be collected while parks are available for camping. No fees are collected during park closure dates. Some boat ramps outside fee campgrounds will charge a $3 launch fee per day, which is valid at any Corps-managed recreation site for day it was purchased.

Some designated swim beaches outside fee campgrounds may charge a use fee of $1 per person over the age of 12 or in a vehicle up to $4. However, if a vehicle has more than 8 passengers over the age of 12, there will be a fee of $1 for each additional individual over the age of 12.

All fees have been set to maintain comparable fee schedules with other federal, state, county and private campgrounds. All fees meet the requirements set in Engineering Publication 1130-2-550. Fee comparability within the same state and district is outlined in Paragraph 9 of EP 1130-2-550.

Seaplanes may be operated seven days a week between sunrise and sunset at all Portland District lakes with the exception of Big Cliff, Applegate and Willow Creek lakes. Once on the water seaplanes shall be considered powerboats and must be operated in accordance with marine rules of the road. Seaplanes in the water may taxi to any area of the lake subject to the powerboating restrictions for those lakes. For more information, see: Seaplane operations at Corps of Engineers lakes.
