Possible Changes to MDE Permit #GA1992S009

This note suggests and rationalizes possible changes to Permit GA1992S009 version 08 issued by MDE to Brookfield, Inc. which allows the former to operate the Deep Creek Lake Hydroelectric Project.The principal suggested changes propose to do away with the TER protocol and replace the mandatory water water schedule with a predictive methodology. Also suggested is to include the lake property owners as major stakeholders in the permit.


On April 1, 2019, according to MDE Water Appropriations Permit No. GA1992S009 (08), a new Permit must be signed by Brookfield in order for the latter to continue operating the Deep Creek Hydroelectric Project. The conditions listed in the current Permit, signed on June 11, 2011, are almost exclusively geared towards specifying when water releases from Deep Creek Lake are allowed for white-water rafting and maintaining the flow in the Youghiogheny river such that stocked trout can survive and be available to the fishing community. Nowhere in the permit is there any mention regarding the rights of those that own property around Deep Creek Lake and who pay most of the taxes associated with the Deep Creek Lake area. A weak argument can be made that the lower and upper rule bands protect the lake property owners, but there have been numerous cases in the past that insufficient water is retained in the lake to allow recreational boating activities. The issue is exacerbated by the fact that lake property owners pay more than 50% of the total tax revenue to the county, while the fishing and white-water rafting communities are not able to quantify their contributions, even if they are indirect. Therefore, the current permit needs to be changed significantly to redress such inequalities.


We realize the MDE and DNR, and probably also the County, have no incentive to change the permit conditions because MDE and DNR have said as such in various meetings. They have no interest in revisiting the TER protocol, nor are they supportive of a water budget model. Given these observations, some of the citizenry of Garrett County have taken it upon themselves to provide rational input to the permitting process by backing the suggestions with data and analysis.


WAM is the acronym for “water allocation methodology.” WAM was develop by residents of Garrett County who realize that a ‘forecasting’ approach makes more sense than hard specified conditions, given the variability of the water level in Deep Creek Lake. WAM should be used every day, in an automated fashion, to define a tentative release schedule for the next several days, or perhaps a week, from the day of the forecast. This should be a great boon to all stakeholders, because they can better plan their future recreational activities. WAM has been discussed extensively in several documents.


A better methodology to predict Youghiogheny river temperatures at the Sang Run river bridge has been suggested for a long time because of the high error rate of the current protocol. Taken from the “Introduction” to Ref [1]: “One of the goals of the MDNR is to use cool water releases from the project to enhance the temperature habitat for trout during low flow conditions in the summer months.“ So why is DNR so hesitant about doing this? Secondly, it has recently come to our attention that very few people fish in the Youghiogheny river stretch from the tail race of the hydroelectric facility to the Sand Run River bridge. This is mostly because of nature conservancy practices that make accessibility along this stretch of the river very difficult. Since few fishermen use this stretch of the river begs the question: “Why a TER protocol for this part of the river?” Why could the cost of operating the temperature gages at the Sang Run River bridge by both Brookfield and DNR (separate gages) and the labor involved

Hurdles to Overcome

From Reference [2, p3-54]: “The mainstem Youghiogheny River and its tributaries, including Deep Creek Lake, are classified as Class III, Natural Trout waters by the State of Maryland. …In addition to basic uses of water contact recreation, fish, other aquatic life, wildlife, and water supply, the Class III designation provides further protection to support the existence of natural, reproducing trout populations. In waters that possess an existing water quality that is better than the water quality standards established for them, the State requires that the quality of these waters be maintained. Downgrading is discouraged by the State and only allowed under certain conditions and with notice and opportunity for public hearing.” Comment:

  1. Trout is stocked so it’s not a natural habitat! 2…. protection to support … does not mean “create a artificial environment” From Reference [2, p. 3-62]: “During non-release periods, high temperatures can extend throughout the river for short periods during the day. However, numerous tributaries and an estimated 9 cfs leakage from the Deep Creek hydroelectric facility create small, localized pockets of cold water in the mainstem.” From Reference [3]: “In 1976, a 21 mile long segment of the Youghiogheny was designated as Maryland’s first Wild River. A state protected corridor along the river runs from Miller’s Run just north of Oakland to the town of Friendsville. This corridor is managed by the Maryland Park Service to preserve the wild and natural scenic, geologic, historic, ecologic, recreational, fish, wildlife, and cultural resources. ” Comment: To preserve the wild and scenic aspects, the river has become mostly inaccessible to the casual fisherman. Other Suggestions 1.The permit needs to specify a requirement for Brookfield to make available on their website, monthly, the lake levels, generator status (not just ON/OFF but also partial and/or one or two generators), and bypass flow status as measured every 5 or 10 minutes. 2.The proposed “water allocation methodology (WAM)” should be used daily to provide estimated forecasts of water releases for each day of the next two weeks. These forecasts should be published daily on Deep Creek Hydro’s website, and over time, have associated with them a probability. 3.Permit Condition 14 needs to be clarified as to a connect-the-points model or a stair-step model for the rule band specifications. 4.MDE/DNR should operate at least two, preferably three, independent weather stations around the lake recording real-time weather conditions at least every 15 minutes, including solar radiation. This data is to be made available via the “Underground Weather,” or some other readily available service. 5.Recasting Condition 19 in the Permit to reflect no guaranteed white-water releases except for possibly special annual festivals or races. Any release is subject to the results produced by WAM. 6.Install instrumentation in the tail race to provide better estimates of wicket gate losses and bypass flow amounts as a function of valve setting. 7.Provide a good measurement of the volume flow characteristics of the turbines during the range of normal operations. Is turbine flow affected by the electrical load or is it vice-versa?
