Overview
Alcova Reservoir sits in central Wyoming, roughly 35 miles southwest of Casper, in a canyon carved by the North Platte River. The reservoir was formed by Alcova Dam, completed in 1938 by the Bureau of Reclamation as part of the Kendrick Project, which brought irrigation water to the region. Today it functions primarily as a recreation area managed jointly by the Bureau of Reclamation and Natrona County.
The landscape here is high-desert Wyoming at its most elemental: red rock cliffs, sagebrush flats, and wide-open skies. The reservoir covers roughly 2,350 surface acres when at or near full pool, offering substantial open water in a county not short on wide spaces. The small unincorporated community of Alcova nearby consists of little more than a scattering of private cabins, a marina, and a few seasonal services.
Visitors come almost exclusively for outdoor recreation — boating, waterskiing, fishing, swimming, and camping. There is no town infrastructure in the conventional sense; plan self-sufficiently and verify which services are operating before you arrive, particularly early or late in the season.
Before You Go
Permits and fees: Natrona County Parks manages the recreation area and charges day-use and camping fees. Verify current fee schedules directly with Natrona County Parks or at the site entrance, as these change periodically.
Season: The reservoir is a warm-weather destination. Full services — marina, boat rentals, campgrounds — typically operate from late spring through Labor Day weekend. Some facilities may be open in shoulder months but verify locally before planning.
Weather: Summers are warm to hot with afternoon thunderstorms possible, particularly July and August. Wind on the reservoir can increase quickly and create hazardous boating conditions; check forecasts before going out on the water. Wyoming weather can shift rapidly even in summer.
What to bring:
- Sunscreen, sunglasses, and a hat — the high-desert sun is intense
- Drinking water in quantity; services are limited
- Fuel in your vehicle before leaving Casper; options near the reservoir are minimal
- Life jackets and appropriate boating safety gear (required by law)
- Cash or card for fees; do not assume ATM availability on site
Getting There
By car: Alcova is most commonly reached by driving south from Casper on Wyoming Highway 220 and then turning onto Wyoming Highway 487 / county roads toward Alcova. The drive from Casper is approximately 35 miles and takes 40–50 minutes. A personal vehicle is effectively required; there is no public transit serving this area.
Nearest commercial airport: Casper/Natrona County International Airport (CPR) is the closest commercial airport. From there, a rental car is the practical option for reaching the reservoir. Verify rental car availability at CPR in advance, particularly for busy summer weekends.
Road conditions: Roads to the reservoir are paved but can be affected by winter weather and spring thaw. If visiting outside the peak summer season, check Wyoming road conditions through the Wyoming Department of Transportation (WYDOT) before departing.
Getting Around
Once at the reservoir, a personal vehicle is your primary means of moving between the marina, campgrounds, and day-use areas. The recreation area spans multiple points around the lake; walking between all of them is not practical.
On the water, boat launches are available at the marina area. If you bring your own watercraft, confirm current launch ramp status and fee requirements with Natrona County Parks. Boat rentals have historically been available through the marina concession — verify availability and timing before your visit.
Walking and exploring on foot is feasible within individual campground and day-use zones, and some informal trails exist along the canyon rim. There are no maintained multi-use trail networks comparable to a state park in larger states.
Things to See & Do
On the Water
Boating and waterskiing are the centerpiece activities when water levels are healthy. The reservoir's relatively wide expanse accommodates motorized boats comfortably. Swimming is popular at designated beach areas — confirm which beaches are open in any given season. Kayaking and paddleboarding are feasible in calmer coves.
Fishing
The North Platte River system in this area is known for fishing, and Alcova Reservoir holds rainbow trout, brown trout, walleye, and yellow perch among other species. A valid Wyoming fishing license is required; purchase one through the Wyoming Game and Fish Department before arriving. Downstream from the dam, the Miracle Mile section of the North Platte is a celebrated blue-ribbon trout fishery worth a visit if you are a dedicated angler.
Camping
Natrona County operates campgrounds around the reservoir. Sites range from basic tent camping to areas accommodating RVs. Reservations and fee structures vary — verify with Natrona County Parks well in advance of busy summer holiday weekends.
Scenic and Geology Interest
The Fremont Canyon just below Alcova Dam is a dramatic narrow canyon with walls dropping steeply to the river. It is a known spot for technical rock climbing. Visitors without climbing experience can view the canyon from above. The red and orange rock formations throughout the area are geologically interesting and photogenic.
Food & Drink
Food and drink options at or immediately near Alcova Reservoir are very limited. The marina has historically operated a concession or small store during the summer season, but hours and availability vary year to year — do not rely on it as your primary food source.
The practical approach is to bring all food, snacks, and beverages you need for your stay from Casper before heading out. Casper has a full range of grocery stores, restaurants, and gas stations. Stock up thoroughly, particularly for multi-day camping visits.
Alcohol regulations on the reservoir and in campgrounds are subject to Natrona County rules; verify what is permitted before your visit.
Practical Information
Emergency services: The reservoir is in a rural area with limited cell coverage. Emergency response times can be lengthy. The Natrona County Sheriff's Office has jurisdiction; in a life-threatening emergency call 911 but be aware coverage can be spotty — identify dead zones early. On the water, the Wyoming Game and Fish Department wardens patrol the reservoir.
Cell service: Coverage is inconsistent at and around Alcova Reservoir. Download offline maps and relevant information before leaving Casper.
Restrooms: Vault toilets are available at campgrounds and day-use areas. Flush restrooms may be available at the marina building during the operating season — verify locally.
Leave No Trace: The high-desert environment is fragile. Pack out all trash; no dedicated waste collection is guaranteed at remote sites. Campfire regulations can change based on fire danger conditions — always check current restrictions with Natrona County or the Bureau of Reclamation before building a fire.
Boating laws: Wyoming Game and Fish and Wyoming State Parks enforce boating safety laws. Life jackets must be carried for each person on board; children's requirements are stricter. Verify current regulations through the Wyoming Game and Fish Department.
Safety
Water safety is the primary concern at any reservoir. Conditions can shift quickly — afternoon winds can generate whitecaps on open water faster than inexperienced boaters expect. Wear life jackets, especially with children. Cold water temperatures early and late in the season increase drowning risk significantly.
Sun and heat: The high desert at elevation (Alcova sits at roughly 5,500 feet) delivers intense UV exposure. Heat exhaustion is a real risk on summer afternoons. Stay hydrated, seek shade during peak heat, and never leave children or pets in parked vehicles.
Wildlife: Rattlesnakes are present in rocky, sagebrush terrain — watch where you step and place your hands when scrambling on rocks. Scorpions are also present. Shake out footwear left outside overnight.
Remote conditions: This is genuinely rural Wyoming. There is no urgent care clinic nearby; Casper is the nearest city with hospital services. Let someone know your itinerary before heading out for multi-day stays.
